Decrimping military brass
 
I found a decent price on 5.56 brass polished with spent primer still in, what do you guys use to remove the primer crimp without cutting too deep into the pocket?

I ise a dillon super swage. Unfortunately ive needed to use it on federal and winchester brass. It does an amazing job making primer holes uniform without tearing them up.

I use the RCBS case prep center.

I use the RCBS primer pocket swager. Fits in standard press and does a very good job of pressing the metal back to its original place. You can adjust it from just removing the crimp to giving a slight flare to ease reinsertion of the new primer.

Do you have any trouble with it deforming the case rims? I have heard this to be an issue with the press mounted swagers. That Dillon looks like the ticket but I wanna try to avoid layin down another 100 bucks on a piece of equipment.

No problem at all. The case is supported by a rod that goes inside the case to the base. Rim never has any contact.

try lee's military brass decapper and primer pocket reamer

I personally like using the the Hornady pocket reamer in my Lyman case trimmer to remove the crimp. I tried swaging the crimp out with the RCBS kit, but I never could get it to work well enough. The good news is that the crimp only needs to be removed one time.

The way the reamer is built it stops you from going too deep and removing too much material from the primer pocket edge.

Years ago I guess we poor boyed it, but all this new stuff probably wasn't out yet. My Dad show me how to use a small punch and set the case over a hole in a heavy piece of metal, that has a hole in it big enough for the primer to fall thru, and we just punched out the primers. We did a lot of live primers because a primer will not go off if punched backward.Then we took a drill bit the size we needed and beveled the primer pocket so the new primers would fit right in the case.

PS Besure if you are doing live primers they are over the hole because if not they will go off if hit backward on a hard surface, like right beside hole.

I beg to differ with you. A primer WILL go off if hit from the wrong end, especially if a crimped primer. You can drive the anvil into the cup and set it off just as it would if you drove the cup into the anvil.

Trust me, I have the scars to prove it.
