Depriming Military brass!
I need to deprime a 1000 or more .223 military brass. Does anyone have a thought as to what I might use to remove the military crimp. Thanks, in advance, for any and all replys.

Military crimp remover, RCBS and a few others make dies for this, check with midway or brownells.

I prefer Lyman's crimp removing reamer, with the cutter chucked in a battery drill. It's a low cost tool, does an excellant job, very simple to use and doesn't remove too much metal.
Lee's Universal Decap die is inexpensive and has the strongest decapper stem in the business. Last edited by wncchester; May 17, 2012 at 04:21 PM. |

Standard FL resizing will deprime them. If you want to remove the crimp from the primer pocket as was said the Lyman Small Primer Pocket Reamer works just fine. If you plan on also trimming I would suggest doing a hundred or so at a time. I burn out trimming if I do more than a couple of hundred at a time.

Dillon makes an nice crimp remover that swages the primer pocket rather than cut it, but its not cheap. It's worth the cost if you will be doing a lot of GI brass (223, 308, 9mm, 45 ACP) in the future.

The RCBS bench tool works well. Same principle as the Dillon, but about $25 less.

I'm cheap, I use a countersink bit chucked into a drill. Not exactly "precision" like the tools mentioned above, but it works and hasn't given me any reason to question the accuracy of the ammo produced.

"I use a countersink bit...hasn't given me any reason to question the accuracy of the ammo produced."
It won't affect the accuracy at all but the angle of a countersink reqires removing a lot of case support for the primers in order to cut deep enough to remove all of the crimp; some of us are uncomfortable with that. The Lyman reamer leaves a very small radius at the mouth of the pocket. |

I used a large phillips bit chucked in the drill press. Works great and set me back about $0.26.

RCBS also makes one.

Dillon 600
I have the Dillon deprimer and it works like a dream. There is a bunch of mods that you can do to it to more 'automate' it on YouTube.

Deprime the same way you do any other boxer brass.
I remove the crimp with a Hornady pocket reamer. If I have a lot to de-crimp I chuck the reamer in a drill that's clamped into my bench vise. Next time, i'll use the new drill press and see how than works.
