Default Tell me about de-priming Milsurp Brass

All I know is that everybody says it's a PITA. Is it really? What tool/s do I need to do it and is it worth it?

I'm not working right now, so it may be worth it. Let me know guys.

The only thing that I have heard about military surplus brass is that it is definitely not crap, it's mostly Lake City, correct me if I'm wrong. I have heard that depriming it is exactly the same as all others, except for the Berdan primed crap, but putting the new primers in is where the problem lies. Milsurp ammo should have all of the primer pockets crimped, so you have to ream those out before you can put in a new primer.

So it's not necessarily the removal, it's reconfiguring the primer pocket that's the problem?

I believe it's just another step that you have to do when loading this stuff up. My father came across alot of this 5.56 milsurp LC brass, and he just chucked up a small ream in a drill press and went to work. Think he has about 500 pieces of it, and has ranted and raved about it's quality once you go through the extra p.i.t.a. step.

[quote=CA357;377075]There are a few different tools available to either cut out the crimp, or swage it back into the primer pocket.

A simple case neck chamfering tool can be used, hand reamers (manual or power driven) or my favorite - a Dillon Super Swage 600. The good news is you only have to do it ONCE.

If you are cutting out the crimp, you should just to try to remove as little brass from the primer pocket as possible so that you don't get it oversize and/or leave the rear of the primer unsupported.

Good to know. Now, what tools do I need? I don't have a drillpress.

Does the swaging press remove the spent primer as well?

No. Your resizing die (or decapping die) removes the old primer.
The swage tool only removes the crimp that is left over in the primer pocket.

Here is an example of a simple hand operated primer pocket reamer. It would work just fine if you don't have bucket loads of brass to de-crimp...

if you try to deprime miltary brass (primers are crimped) with your decapping dies, it will bend the decapping pin.

you need to get a manual miltary brass decapper and primer pocket reamer or swager (to remove the crimp) from lee or rcbs.

they are very inexpensive.
