Primer Pocket Fixing........ the Lyman tool

.

Today, hitting the loading bench and cranking out some fodder for a few match rifles.  Going through the motions in my head over coffee, and planning the time to be used wisely, this widget came to mind.

Yes, I do mentally plan my reloading time, and yes.... I do use this Lyman tool thingie......

I hope to finish this batch of .223 today, and move on to a more interesting loading project.  That would be.... finding the load my Lovely Garand likes more than any other. I plan to use Liberty in next months match, and wish for something just a bit better than Greek Surplus to do it with.



Faced with a large mixed batch of 5.56 brass, in which about 80% have crimped primer pockets, the Fat Man had to make a choice. The crimp has to go..... but how to go about it?

In the past I have used my RCBS primer pocket swaging tool to good effect.... except I managed to bend the small case rod and never got around to getting a new one.

Also in the past, I have used a case deburring tool to cut away the crimp, and that worked quite well. On the other hand, when faced with a pile of little 5.56 cases about a thousand deep, my fingers begin aching at the very thought of using the small tool for all those.

Enter the Lyman Case Prep Multi Tool, recently acquired for just such an occasion.

I was attracted by the large knurled aluminum handle. It just looks comfortable to use. The design allowing the tool heads to be switched at will..... that's pretty cool as well. Now, make the whole doohickey hollow, and make the inside a storage compartment for a good assortment of case prep tool heads.... that sold me. No more digging around inside my loading bench for a handful of case preparation tools.

The gadget comes with tool heads designed for inside and outside case chamfering, primer pocket reaming/decrimping, and primer pocket cleaning. Both large and small primer pockets.

In use, I installed the primer pocket reaming and cleaning tool heads. This allowed me to simply flip the tool over and do both operations as needed on each case.

The results? Well, clicken to embiggen the image below to see for yourself. The reamer doesn't really fell like it's doing much, but looking at each case we see the crimp is gone and a very nice bevel in it's place. Priming the cases now is not only possible, but smooth and easy.


For the price, it's a pretty darn good tool. I've used Lyman case prep tools for ages, but they continue to develop new ones all the time, and the skull sweat that went into this one makes it worth owning.

Carteach: Two (not worn out) thumbs up!

Don't be hating on the HXP Greek ammo. It's actually better consistency-wise than Lake City.

And for primer pocket crimp removal, I loves me my Dillon swager. I was so reluctant for so long because of the price, but once I got one and started using it, I can't imagine processing brass without it.

+1 on the Dillon primer pocket swager.

Wilson makes a shorter version of the Lyman tool which, I discovered, fits nicely in my drill press chuck. Set on slowest speed, it does a very fast and terrific job on chamfering case mouths, inside and out.

Amazon has the RCBS version ("RCBS - Deburring Tool") which looks exactly like the Wilson tool.
