LC Brass and Decapping / Depriming

[ExtremeX]

Is it recommended I use the Lee (or other brand) universal depriming and decapping die to remove the LC primers in a separate step since they are crimped?

I was thinking of just using my RCBS FL Die set, Die 1 is decapping / resizing before going to swaging and trimming.

My RCBS seems to work just fine. Also, if you don't have a swagging tool, you can cut out the crimp using a drill and an 82 degree countersink; just don't go too deep.

Yes, I always use the Lee full length resizing die for decapping spent primers in all the LC brass I reload. The primer crimp is not an issue when decapping. It matters when you're trying to put a new primer in the primer pocket. You'll need to swag the pocket. Visit youtube on the many ways to prime crimped primer pockets.

I've used both the Lee and RCBS full length dies to size and pop primers out of LC brass. Both do pretty well, although you really have to crank down on the pin for the Lee die to keep it from sliding out of the die. FWIW, the Lee die seemed to do a better job of sizing the LC brass for use in a semi auto (LR-308 using a DPMS SASS barrel, super tight headspace). I had lots of issues when I started using the RCBS die, rounds wouldn't chamber fully. I had to trim .007" off the base of the die to get it to bump the shoulder down far enough to chamber.

For removing the crimp from military brass, I've found the easiest way for me is the Lee chamfer tool, normally used for the case necks after trimming. I just do 2 or 3 turns by hand in the primer pocket, it doesn't take much to remove the crimped edge.

I use a Lee universal decap die so I can decap dirty brass before tumbling with stainless steel media as it helps clean out the primer pockets. I remove the primer crimp with a chamfer/debur tool

I use the lee punch and base tool with a hammer or a seperate decap die. Then I use the Dillon Super Swager or my new Lyman Case Prep Center to remove the crimp. I have tools RCBS(swager and a cutter),lee cutter,Lyman hand cutter and maybe a few others I have tried but the Dillon Super Swager or the case prep center(whatever brand you prefer work the best for me.

Yep, agreed. I just got through with decapping 500 cases of LC 7.62, and I had to tighten that collet pretty well (I have Lee's universal decapper, too). But the tool does a fine job of it.

A buddy of mine used the RCBS Primer Pocket Swager, and while it's great at putting the pocket dimensions back to spec, unfortunately it doesn't get quite all of the crimp out of there. There was just enough on it to still grab the side of the primer's cup and make it go in diagonally, thus crushing it. He had to do just like FMJBT did and chamfer the primer pocket just a little bit. That solved the problem.
