Today I choose to become reacquainted with my Armalite AR180b. It's a sweety, with an Eotech 512 mounted on it. All this has been covered before here.
I took two brands of ammunition with me, and decided to compare. Yes, I can shoot for shear enjoyment! But, I also enjoy discovery just as much.
I have mentioned the Privy Partisan .223 on this blog before, and decided to compare it with the Wolf brand of the same ammunition.
Both function well, and accuracy is not so far different that further testing would not be needed to be sure which is better. My impression is the brass cased Privy is the more accurate of the two, but I'm not certain of that without testing. Today was more about fun, and I wasn't really bearing down on the technique.
One thing noticed at once, as it's glaring, is the difference in impact point. The Privy struck about six inches lower than the Wolf from my rifle.
On this target, the Privy brass cased .223:
And on this one, the Wolf steel cased .223:
I think the difference is in velocity. Not having my chronograph set up today, I can only guess. But the recoil pulse was quite different between the two different rounds, ejection was very different, time back on target was different, and slide velocity seemed quite different.
The Privy Partisan seemed to be stepping along much faster, and thus was out of the barrel before it could begin rising much from recoil. This is called 'bullet time in barrel'. The slower a bullet travels in the barrel, the more time it has to be acted on by recoil before it leaves the firearm. This is why a .38 special fired in a .357 pistol will impact much higher than the .357 does. It's not because the .357 magnum shoots flatter (it does, but that matters little at 25 yards). It's because the weapon begins rising from recoil before the bullet leaves the barrel, raising the impact spot on target.
Perhaps these videos will help show the comparison better. In one, the empties are ejected rearward and the recoil pulse is clearly lighter. This was the Wolf ammunition. In the other, the empties eject forward and the recoil is quite sharper.
As I said.... it's mostly subjective. On the other hand, I made a pile of empties and had a ball. The range was recently upgraded, the weather was perfect, I had the place to myself, and life was just really good for a little while.

Welcome back. . You know I have a Wilson Combat Tactial AR15 with a Eotech site that would just LOVE to come out and play.
The nearest place to me to shoot anything sizeable is 50 miles away, unless I want to use the LEO range.
Now that was fun!
Better still, I can access your blog!
One thing we have out here is long range opps. You should try it some time.
Welcome back! Looking forward to more!
"life was just really good for a little while."
Isn't that the real reason why we shoot? :)
Glad to see you are back posting again. I hope things worked out for the better as far as what ever caused you to take an extended hiatus from your loyal readers.
I am not as meticulous as you are when it comes to testing different ammo. I have had much better luck and much better accuracy with the Prvi Partisan than I have had with Wolf ammo.
I generally shoot 7.5x55 Swiss from a K31, 6.5 Swedish from what is commonly known as the Swedish Mauser (I'm told it's not really a Mauser), 7.62x39 from a Yugo SKS and 7.62x54R from a Mosin M38 or M44.
In all of the above calibers, I have found that Prvi out performs Wolf. It could be because the Wolf is the steel cased ammo and the Prvi is brass cased. I'm not sure the casing makes that much of a difference.
I'll wait for your more scientific method of testing to see what your results are.
One of the private ranges I am a member of just came up with a new rule. We are not allowed to shoot SKS nor any AK-47 type rifle on the range and we are not allowed to use steel-cased ammo of any kind.
I asked them to clarify because I thought they meant steel-cored ammo instead of steel-cased ammo. They said they mean both and that neither is allowed. Punishment on first offense is loss of range privileges for 90 days. If they catch you twice you are banned from the range for life. No refund of membership dues will be coming your way should you be banned.
I can see their point to some extent because they are a semi-private range. They allow the general public to shoot there on the weekends if they are willing to pay the exorbitant, hourly range fees and almost 3 times what a member pays for a round of skeet, trap or sporting clays, etc.
We get some idiots that want to shoot up everything and can't even hit the 30' high berm many times. I just leave when the riff-raff shows up. I wish they would just go completely private and let the paying members that went through a safety class and test before we were allowed to become members shoot what we want within reason.
I don't want to shoot a cannon, howitzer or any such ordnance that one has no idea where it will stop but I do have a large collection of old military guns and surplus ammo. I think that $600 a year for dues should get me a little more consideration than the average baggy pants, gold tooth nimrod from the barrio.
Molon Labe,

Were they both 55-grain loads?
I recently bought a mess of Privi Match 75-grainers that did well enough to keep me at just over 400 during our last match...
