Fund raiser to benefit the Wounded Warrior Project (Now with MORE Update!... and custom leather even!) (Over now)





. (Make SURE to check the prize list again, as more are added all the time!)


We are going to have us a little fund raiser here, and Carteach will be shipping out some pretty neat stuff when it's over. The object of the funds raised will be..... The Wounded Warrior Project, and it's tough to think of anyone more deserving of our help.

Here's how it's going to work: I have some goodies to give away, and will be drawing names of the lucky winners (on video here at Carteach0) sometime the end of September. The names get into the hat in one way, and only one way. Anyone who makes a donation to The Wounded Warrior Project and forwards me a copy of the email receipt is in.

For every five dollars donated, the donors name will be entered in the drawing. In other words, a $40 donation gets you 8 entries. Not only that, but the donor specifies which giveaway item they want to be entered for, and can split their entries up on different prizes.
Once the donation is made, forward a copy of the receipt to me at ArtWelling1@gmail.com, specifying which items you want to be entered for. As more prizes come to light and show up here, you may let me know if you want your entries changed to a different item, although it would better to just make another donation and get another entry (g).

What is in the prize bag? Keep checking back, as I expect this list to grow... and that's being worked on by the lovely and resourceful person of Ashley Burgess, of Laura Burgess marketing, a firm that specializes in representing companies we shooters know and love. This family operation is an American success story, and they are good folks indeed.


From Dennis Badurina, proprietor of Dragon Leather Works, comes a hand made holster for the 1911 pattern pistols. Dennis's work has been reviewed by Gun Blogs everywhere, and I needn't expand on the artistic quality of his work.. This holster is currently on it's way to be photographed by Oleg Volk, one of the best people in the business, and might be seen on his site in the future. After that, Carteach gets to look it over for an upcoming article, and then it becomes yet another great prize in this fund raiser. Whoever wins it will be getting a unique holster desired by many, many people indeed, with the added mystique of being a well known piece seen widely on the blog-o-sphere.




Holster only... pistol not included. Image by Oleg Volk.


From Laserlyte, several offerings for the cause....

One of their new units designed for the Ruger LCP, and reviewed here before. I own one of these myself now, and rely on it for daily pocket carry.


And.... another unit designed for the KelTec PF-9. This one replaces the rear sight, meaning the owner does not have to buy a new holster or modify one to fit. It's neat technology, and works.

And from BLACKHAWK!, a sweet leather pancake holster fitted for the 1911 pattern.


From Sentry Solutions, TWO
Armorer's kits. Yes, TWO... so twice the chance of winning!

And, Sentry Solutions sweetened the pot by adding TWO Gear Care Kits, along with enough extra Tuf-Cloth's to make all four kits bulge! I envy the winners on these kits... I'll have to buy one for myself.



And now..... something from 'Ol Carteach himself. Some of the folks here know I craft jewelry, amongst my other sins. Well, here is an example of such silliness. It's a moonstone heart, mounted on a hammered silver bracelet. It's hand made, and I consider it once of the nicest and most graceful pieces I've been fortunate to make.



NASCAR fans.... Here are a pair of collectable die cast metal cars. Todd Jarret's #88, and here is a link to the exact item on Amazon so folks can see what they are. I have decided there is no way I'll un-box them for photos as these are in their original box and untouched.
1 of 2000, from the Brookfield Collectors Guild. They will come with a bonus Ford Model-A die cast collectors car that is gorgeous, and also untouched in it's original box . This set is worth in excess of $300, and has been donated to the cause by someone who wishes to remain anonymous.
LinkFrom John Rost, fellow blogger and all round good guy, comes two brand-new-in-the-wrapper AR-15 magazines. Made by C-Products, these top of the line 30 round magazines have the highly desirable grey anti-tilt followers. To sweeten the package, Carteach is adding enough ammunition from his own cache to fill the magazines.


From Patrick, reader, supporter of the cause, and fellow blogger, comes a new copy of the latest edition of Boston's Gun Bible. It's about 2" thick, and chock full of shooty goodness.


From JC Jewelers in Sebring, Florida, a Morgan silver dollar, dated 1878 and bearing an 'S' code. I am no coin expert... but to my eye this coin looks.... well.... startlingly good for being struck 130 years ago.

From JT, who donated the coin: "
1878 was of course the first year for the Morgan, the San Francisco mintage is emblematic of American adventure and prosperity at the time, and not least in my mind, it was the year that 23 year old John Browning began work on his first gun, the beautiful single-shot rifle that later became the iconic Winchester 1885. Anyway, holding a coin like that gives me a sense of connection that I hope your raffle participants will also enjoy, and this one is nearly untouched and still mint-frosty after all these years. "


And.... one last prize, given by North, with a blog by the same name. A magnificent set of new books, all geared towards shooters of the gentler sex (Yes... I can almost say that with a straight face). Five books, each centered around shooting and self defense for women. I could not have picked a better set myself, and lucky is the person who wins these in the drawings. North did a fine job choosing these!

Armed and Female, by Paxton Quigley
The Cornered Cat, by Kathy Jackson
Thank God I had a Gun, by Chris Bird
The Concealed Handgun Manual, by Chris Bird
and Personal Defense for Woman, by Gila Hayes


Now.... how did all this get started?
Friends and readers, Carteach had an idea.

Now, I don't want you to get that look again. There is no reason to run away this time. Really, this is actually a good idea, and the chance of disaster is reasonably small.

There came notice that a gift would be arriving in the mail very soon. A magnificent gift, really... a laser from Laserlyte. Their products are pretty good stuff, and I've reviewed some of them here in the past.

Well, it turns out the unit being sent is one I already have, and use on a daily basis. Discovering that, the 'ol brain turned to finding fun, useful, and mostly legal things to do with a spare laser designed to fit the Ruger LCP. The very first idea was to run a contest here on the blog and give the device away to a worthy reader. After all... where would this site be without our loyal readers?

Then.... another idea occurred. Not simply give away the loot, but give it away with a purpose... and a very good purpose indeed.



A few notes:
  • This fund raiser is being run solely by Carteach0, and is not affiliated with anyone else. That means it ain't their fault, just mine.
  • Prizes have been donated without conditions, and all will be shipped within a week of the drawing. All shipping and extraneous costs will be covered by Carteach0. Time for the fat guy to scrape the penny jar clean.
  • Carteach will respond to every single email entry that comes in, so if you don't get a response within a day, holler, scream, and shout in any particular order you choose.
  • Fellow GunBloggers.... you know what to do!




Blog Roll Fix'uns

The blog roll here just got updated in a major way.... as in I created one. If I have missed yours, or a worthy blog you care to see there, please let me know!

Thanks!

Each time a reader clicks on one of those ads over there, 'Ol Carteach can put one round of ammo in the range bag! Click away my friends.... and thanks for putting a dent in the fat man's ammo budget!

An interesting question of chamber pressure.....

.
This question popped up in my in-box, and I thought it worth sharing:


Hi,

Someone on another blog suggested you might be able to answer this question.

I was at the range recently and I ran into an old timer who had an M1
and reloads his rounds (I have only a little over half a century under
my belt so far :-)

He claimed, I seem to recall, that chamber pressures on his M1 were of
the order of 48,000 PSI rather than the usual 60,000+ on a bolt-action
30-06.

Today, it seemed to me that this should not be the case, since the
bolt on the M1 does not unlock until the combustion gases bleed down
the gas port and operate the piston. So, there should be little
difference between the pressure that develops in an M1 compared with a
bolt-action 30-06 with a comparable length barrel. At least that is my
first thought.

Can you comment?

Perhaps he uses less powder in his hand-loads.


An interesting question. The SAAMI specification for chamber pressure in the venerable 30-06 round is roughly 50,000 Copper Units of Pressure, which does not exactly relate to PSI (which is much higher). It's taken by measuring the deformation of a pure copper pellet which is contained in a pressure vessel attached to a tap port on the chamber of a very special pressure measuring 'gun'.

The question itself has some flaws, chief of which is this: One cannot measure chamber pressure without such a rig. One can only guess at the pressure, and no matter how good the guess the factors involved are myriad. Bore diameter, bullet diameter, chamber dimensions, bullet weight, bullet jacket composition, powder load, powder type, cartridge casing thickness, primer type, free-bore ahead of the chamber, temperature at firing.... each adds to the mix, and any single one can make huge changes in chamber pressure.

The reasonable answer is to plan on staying well under the maximum chamber pressure, leaving a wide margin for error in the interest of safety. Most firearms are engineered with such a wide margin, being capable of significantly more pressure than the cartridge would normally have. This is the thinking behind 'proof' loads, which have been used since the inception of firearms as a means of proving the integrity of the barrel. Typically a double powder loading back in the day when the charge was poured into the muzzle, a bullet rammed home and some intrepid soul pulling a string tied to the trigger.

As for the M1 Vs. Bolt Action question, I would have to disagree with the gentleman who thinks them inherently different. I can't see why pressure would be any different, given all other factors being a match. Right up until the bullet passes the gas port, and then all bets are off as pressure is bled away to operate the action of the wonderful M1 design.

IF all other factors were equal.... and that is the point. There are so many factors, each vitally important, that the rifle action itself is of little consequence by comparison right up until the op-rod shoves the bolt back and cycles the action.

More to the point when considering the difference between the M1 Garand and a Bolt action rifle of the same caliber is the Pressure Curve of the load. In other words, given a safe and reasonable chamber pressure... what is the pressure in the bore when the bullet finally passes the gas tap port? That is the pressure which will operate the action, and given a load which has too high a pressure at that point the action may be damaged.

I hope this answers the question.... and I have written it out as best I know how. I am certain there are folks more expert than I amongst the readers here, and I would welcome thoughts and opinions on the matter.

Lord knows how I became the expert..... I'm just a fat old school teacher from Pennsylvania (laughing to and at myself).

Sure, there's an App for that..... a free shot timer!


Here's a glimpse into the way Carteach's head works:

We are sitting in a good friends kitchen, enjoying morning coffee and stunningly good bacon and egg sandwiches. Amongst the many things discussed is her son's ability to solve a Rubik's cube. In fact, the young man (A 22 year old EMT and medical student!), is quite quick at the mental task. In more point of fact, his mother mentions he has a special App on his phone just to time the feat.

Carteach's head goes 'BING!', and this train of thought takes place:

Rubik's cube timer....

Timer?.....

Shot Timer?.......

SHOT TIMER?.....

FREE shot timer?.....

FREE SHOT TIMER APP !?!

Of course... Naturally... Carteach whipped out his Android phone and did an immediate search for a shot timer application. Lo and Behold... there is one. 'Shot Timer', by 'Futurewise Technologies'. About 90 seconds later, the shot timer App is downloaded and I am gleefully clapping my hands at the kitchen table, testing the application.

Later that day, arriving home just at last light, I had enough time to load up and run one ten shot string over the new shot timer application on my phone. It worked like a charm.

Now, it's not fancy... and it demands access to things on the android phone that I can't see related to the functions of the shot timer. It won't record results to a database, and doesn't provide an instant text feature so you can gloat to your friends with screen captures of your incredible shooting prowess.

What it does do is work. It records your string time and split times. Using an ISSC M-22 pistol fitted with a Laserlyte FSL-3 laser, I loaded up two magazines with five rounds each. Setting the timer for a five second delay til the 'BEEP' which begins the string, I holstered the pistol and hit the go button. Five eternally long seconds later, the beep came and I drew to fire five. Running the pistol dry, I reloaded and sent another five into the target.

With that, the sun winked out over the bamboo forest and darkness fell with swift abandon.

Looking at the screen on my phone, I saw the timer caught every shot faithfully, with total time on the string and split times as well. 3.2 seconds to draw and get on target, split times on shots of about .3 seconds, and a three second reload. Not too shabby for a fat old school teacher, shooting from a concealed carry holster.

8.09 seconds to put ten rounds onto the target, with a draw and a reload in there someplace. I'm satisfied with that for a start, even with being a mild mannered and easy to shoot .22 rimfire.

I have wanted a shot timer for years now, but just could not bring myself to spend the money. Now this comes along, and it's free..... you hear that? FREE!! (Cackling like that old guy who lives alone in a trailer far out in the Arizona desert).

It's probably not something I'd rely on if I was a competition shooter, but for fat 'ol Carteach who just piddles along trying to get a little better each time..... it's exactly what I wanted.

Making a long story short.... restocking a home defense shotgun

.



Some time ago I wrote a piece describing the evolution of an old Remington 870 scattergun into the quintessential 'household home defense' gun. It was fairly simple affair, involving nothing more complicated than replacing the barrel and adding a buttstock shell holder. In reality, nothing more is required for a home defense shotgun. More toys, gadgets, and add-on widgets can actually cause more harm than help, as simple is always better.

That said... I have taken a leap and added a feature to my Remington home defense shotgun. A folding stock, and a very special one indeed.

The Knoxx recoil reduction stock is indeed a gadget, but unlike so many... this one actually works. On top of that, it has passed the 'Carteach0 Gorilla of Doom Destruction Testing'. In plainer words, I attempted to break the stock in some very unreasonable ways. By simply pulling it apart with my bear hands (pun intended), and even beating it against a range bench (shotgun won, bench lost).

The Knoxx stock uses fairly massive internal springs to absorb and spread out the recoil pulse of the heavy hitting shotgun. The kick is still there, but instead of a
painful jab it's reduced to a long 'shove'. This technology shines in two areas; Letting recoil sensitive people shoot the thumper without fear, and aiding in shear controllability of the shotgun. It's hard to argue that heavy recoil reduces ones ability to control a weapon, and mitigating the recoil helps the shooter stay on target. This is the point behind every rifle muzzle brake and ported competition pistol.

Replacing the Remington wood with the tough Knoxx polymer and steel buttstock is a five minute job requiring only one special tool, which is included with the stock. That tool is nothing more complicated than a long allen key that makes the job easier. Replacing the forearm is a slightly longer job, and it does require a special tool not supplied by Blackhawk with the Knoxx stock. It's a type of spanner wrench designed for the Remington forearm nut, and can be found for about $25 at most gunsmith tool suppliers.

I'll save the detailed story of swapping over the stock and forearm for another post, and stick to the range report with this account.

Why move to a folding stock, aside from the 'totally cool' factor? Well.... my thinking is this: I reserve this shotgun for home defense, and in working through the home with it I find it can be awkward, even in it's short barrel form. One almost has to do a 'Gun-Kata' to make it work smoothly and efficiently.

The problem is... even with the shorter barrel, the whole weapon is about as long as the hallways are wide. Doors are another problem entirely, especially entering a room while 'slicing the pie' with a long gun. Shouldering the weapon means sticking it out in front you about three feet, and that's pretty tough to maneuver in tight spaces.

The answer, of course, is a shorter weapon. Making the barrel shorter than 18.5 inches costs $200 in taxes and a bucket load of paperwork to do legally. Do it illegally, and the missing few inches of pipe could literally cost you your life (as has happened before).

So, the stock must grow shorter. There are three basic options when it comes to shortening a shotgun buttstock.
  • Lose it entirely, and go with only a pistol grip. This makes it as short as possible, without paying the federal taxes on a short barreled shotgun. It is a popular choice, but gives up the choice of shouldering the weapon.
  • An adjustable length stock (AKA: M-4 type stock). These too are popular, and work well within their limits. They still leave the weapon fairly long, but are shorter than a full stock version. The fun part is... just squeeze a lever and the stock can grow to full length.
  • A folding buttstock... presenting the best part of having a pistol grip stock, and the option of easily going full length when desired.
I chose the folding stock route, but only after having been introduced to the Knoxx recoil reduction stock by the folks at Blackhawk, and their spokesman Todd Jarret. Having met the stocks designer and seen it in action, I was satisfied enough to plunk down my plasti-cash and buy the tactical folding unit for myself.

I'll admit, it was the range time that caught my interest, but what really sold me on the stock? I tried to tear it apart with all my strength.... and I couldn't budge it. I like that kind of engineering and quality. It's as idiot proof as possible, and I need that in a product.

In shooting with the unit installed, it feels a little different at first. The shotgun's recoil pulse is spread out over time, instead of whacking the shooter like a punch. Return time on target is much faster, and shooting with the pistol-grip-only caused me no pain at all.

The one worry I had with shooting a pistol grip shotgun... accuracy. Yes, a shotgun must be aimed, and not just pointed. This notion is magnified at defensive shooting distances, often measured in feet instead of yards, because the shot column does not spread at short range. Shooting a full stocked shotgun from the shoulder makes the job of aiming the weapon far easier. Shooting from a low position with the pistol grip certainly makes the task of hitting the target harder. The question is... does it make it too difficult? Enough to negate the usefulness of the shorter weapon?

My theory was it would be harder to use accurately, but like most forms of shooting, practice would make it work. There is not a shred of doubt in my mind.... it's far easier to control the weapon and shoot accurately with the stock extended and the weapon shouldered. That said, with the stock folded and shooting from the low position, reasonable defensive accuracy can be attained... with practice.

In the following video, I describe some of the features of the Knoxx folding stock, and then put it through it's paces. Shooting longer distances, it's far more easier to shoot well with the stock extended. Moving to the 'up-close and personal' range of about ten feet, it was possible to lay down impressive and accurate fire, again.... with practice.

Please note the very first time I shot pistol grip only, from low position, at short range. Only three of the five rounds registered solid hits, with the last shot merely digging dirt under the target. It took some serious consideration on my part to leave this embarrassing video un-cut, but it so perfectly illustrates the point. A shotgun needs to be aimed, not pointed, and only practice will make that happen. By the second run I was better, and after five runs I had no problem hitting center mass with every shot while moving at a fair pace.

I should note... I burned through over one hundred rounds of twelve gauge shooting with the pistol grip, and my wrist feels just fine. The recoil reduction feature works.



My final thoughts? I like the Knoxx stock a great deal, and it will remain on my home defense shotgun. The folding option is simple, strong, and intuitively easy to use. For a defensive shotgun, it's a winner.

As for the recoil reduction feature, I like it enough that I expect I'll order a full length version for another of my shotguns that see's time on the trap range. I like the idea of not being mule-kicked one hundred times in a row while shooting trap, and my shoulder agrees.

PHHTttttttt........ a very quiet .22 round.

.


At last count I had nineteen different types of .22 rim fire ammunition. This morning, I have to make that an even twenty. Once again I have fallen to the curiosity of an offering previously unknown to me.

This time it is, perhaps, the most unusual .22 rim fire round I have seen. Aguila, a company not afraid to offer something different, brings us it's 'Sniper Subsonic' round with a 60 grain solid lead bullet. Yes.... 60 grains.

The heaviest .22 rim fire normally encountered is 40 grains. Higher velocity rounds usually drop that to 36 grains, or even 30 grains.

Aguila managed to squeeze that huge slug into a long rifle sized package by taking a unique route. They used a .22 short case, with a reduced powder charge, and loaded a very long lead bullet into it, bringing the whole cartridge out to .22 long rifle length. The SSS round looks the part too, with half the cartridge length being lead bullet. That's more than unusual, it's down right strange looking.

The idea is fascinating, with the heavy bullet retaining substantial energy while the low velocity and charge give greatly reduced noise. The problem with this approach is one of bullet stability.

Heavier low velocity bullets require a rapid twist rate to stabilize the bullet in flight. Lighter high velocity bullets can use a slower twist rate to accomplish the same stability. Bullet design also comes into play in the equation. Even the type of rifling can have an effect.

Typical .22 rim fire firearms shooting a 35 to 40 grain bullet at 1000 fps work well with a 1 in 16" twist rate, and this is standard for these weapons. A .223 center fire shooting a 60 grain bullet at 3200 fps usually works well with a 1 in 9" twist.

A .22 rim fire shooting a 60 grain bullet at subsonic velocities? A rapid twist would be in order, and its doubtful that 1 in 16" will do it. The test is simple. Load an accurate .22 rifle with the new ammunition, sight on a reasonable target, and note the results. That is exactly what I did, and the results are shown here.

The rifle chosen was a CZ452 Trainer, and is exceptionally accurate. It has shown a tolerance for various cartridges, without being overly picky about what it will shoot well. The long barrel and deep rifling may have something to do with that, as well as the tight bore. This rifle, even with open sights, constantly surprises shooters with it's consistent ability to group tightly.

Setting simple 4"x6" card stock targets at 50 feet, several rounds were fired. Only a few were needed to answer the basic question. The very first round was a classic keyhole, as was every round after. The Aguila 60 grain bullets simply would not stabilize in the 1 in 16" twist CZ barrel.

Fired at both a paper target and a block of pine, the imprints are clear sideways impacts of a bullet tumbling in flight.

Perhaps this ammunition would be better suited to a .22 wearing a custom rapid twist barrel, as many folks have fitted to Ruger 10/22s. Also, it might be a perfect round for an AR equipped with a rim fire conversion, especially if it has a suppressor can installed. For my .22's, all of which have 1 in 16" twist barrels, I'm afraid this Aguila offering is useless.

A note of thanks!

Some folks have written and asked about the Google Adsense ads I've allowed on the blog. The general consensus is..... "Whassup?"

The answer is simple, and times are hard all round. For every click of an ad on the sidebar, Adsense is tossing a few pennies in our direction. It breaks down to about one round of regular ammo for every click, and you can bet that is exactly how it will be spent.

So click away! Or, as I like to think about ... Click (Bang!), Click (Bang!).

That time of year again... choosing safety glasses

.


It's time again... when I pick out the safety gear to keep my students alive and healthy. That means another round of testing, as I take the job seriously. The other day another instructor asked about safety glasses, and I explained the ones I had chosen for my kids. He asked how I knew they were good enough... and I replied they had been tested with a 12 gauge shotgun at 20 feet, and survived. That seemed to settle the discussion. (Smile).




Shooters can usually be found with ear protection and eye protection. Earpro and Eyepro by the slang words. Smart shooters.... are seldom without both.

This post is about eye protection, and what we can expect from it.

In choosing good eye protection, we are faced with an awful lot of choices. So many factors come into play. Price, style, price, quality, price, price, and price. This opinion is based on a decade of buying eye protection for my students. Yes, price has always been a factor, but not the most important. Keeping my students eyes in place and operating is the main goal. After that, price becomes the deciding factor.

In studying the available choices, the single biggest pointer towards protec
tion is clearly the rating of the lens. There, we are faced with three levels. The first is no rating at all. Such 'safety glasses' are little more than cheap plastic glasses... possibly worse than having nothing at all. No-rating glasses offer little in the way of protection. Under impact, they tend to shatter into sharp chunks, rather than deflect and absorb the blow. The resulting fragments can be driven into the eyes, causing worse damage than an unprotected impact might have.

No-rating 'safety glasses' may be the lowest of the low, but that doesn't mean they are the cheapest of the cheap. In fact, price is really not a reflection on the safety rating of the lenses. The highest rated lens may be found in a $5 pair of glasses, and typically is. On the flip side, some quite expensive shooters glasses may not be all that highly rated, trading safety for style.

How does one check lens rating? With a sharp eye and good light... that's how. One must look for some specific figures on the lens itself, or if the lens is part of the glasses, the rating may by on the arm instead. What we want to see is the letter 'Z', followed by the number 87. Put a '+' sign after the Z87, and you have the highest rated regular safety glasses you will typically find.

Z-87+ is what Carteach0 buys for his students every year.... and he pays no more than $5 a pair for them, even in the stylish and effective wrap-around type.

Once we have a Z87 (or higher) rated lens, what kind of protection can we expect? Here, things get pretty impressive.

The no-rating glasses shown above, with the amber lenses, were the first victim of the Cart
each0 testing apparatus.... otherwise known as a sheet of thick metal plate and a S&W K-22. The plate was set up and angled just so, and when fired on with the accurate .22 pistol a swath of bullet fragments would dependably spray to one side of the plate.

As the test board to the left shows, a round or two fired into the test plate would leave nothing alongside it unscathed.

The amber no-rating glasses didn't stand up to a single fragment storm, shattering on the first hit. Both lens and frame came apart, littering the area with testimony of the 'safety glasses' ineffectiveness.

Low budget Z-87 safety glasses bought from the hardware store fared much, much better. Hit with no less than four blasts of shrapnel from the .22 bullets hitting the aluminum plate, they showed not a scratch on either lens. In fact, a paper had to be placed behind the glasses to verify the spray pattern, as this tester couldn't believe they were being hit at all. The frame did show some impacts, but the lenses came away unscathed.

Having demonstrated the difference between Z-87 rated lenses and unrated lenses, Carteach decided to move right up to the big guns.... and testing that was much more fun. Full frontal with 12 gauge shotgun and #8 bird shot. A serious test of any lenses effectiveness.

Leaving the disgraced un-rated lenses behind, the shotgun tests were done with low budget Z-87 EOS safety glasses from the hardware store, and some lenses donated to the cause by a reader, made by ESS and Wiley-X. Surprisingly, all survived shotgun blasts that tore apart the Styrofoam mannequin heads used to support the lenses.

As the following images show, at distances as far as 50 feet, and as close as 15 feet the lenses easily survived multiple hits with #8 bird shot fired from a 12 gauge shotgun.
























Clearly, typical Z87 and Z87+ rated lenses hold up to impressive damage. Direct impact from a 12 gauge shotgun at 15 feet... amazing. The lenses, at closer ranges, were driven deep into the foam target, but the lenses themselves were never penetrated by the #8 shot.

Testing was done at this point. A full load of bird shot at 15 feet... If anything more damaging than that happens to a shooter, all bets are off anyway.

The failure point was not the lenses, but the frames. No matter the brand tested for this post, they all gave up pretty quickly. Perhaps that would be a reason to spend significant cash on safety glasses... for frames that would hold up to the same as the lenses.

Carteach's choice? Inexpensive Z87+ wrap around glasses. The same one bought by the gross for his students. In fact, shaded versions of the same glasses can be found in every Carteach0 vehicle, used as driving sunglasses. This makes sense, as the dangers from flying glass and debris in a car accident easily rival that of the shooting range.

Now.... to finish off the test lenses in a way that leaves no doubt. OO buckshot at 15 feet, launched by a full choke 12 gauge tube.

Armed response video training....


Guess what's in my DVD machine right now?

In fact... I've got about 8 hours of this material to work through.

Would Carteach like to be at... say.... Rob Pincus's upcoming class on defensive shooting? You bet! But... time, money, travel... all are simply beyond reach at this moment. Instead, fortune favors us and we get an opportunity to work through some training video material from Armed Response.

Is it a replacement for actual hands on training with live fire? In no way... and happily that's the very first thing they say on the very first video. From there, they launch into basic safety procedures and concepts, and then into gun handling techniques. In fact, it's very much like a live training course should be... only on video in my living room.

Look for (probably several) full blown reviews as I proceed through the training videos at my own pace.
