I got my hands on a big bag full of brass 7.62x39 berdan primed cases. As I also have primers I thought I'd get busy and decap some for this coming weekend's shooting trip.
I used to use a sharp chisel like tool to pierce and pry the old primers out. Geez, what a pain. So after seeing some other ideas for decapping with water and a punch I came up with this simple tool using things I had on-hand:
Basically it's a short piece of 1/2" copper pipe (1-1/8" to 1-1/4" long) and a 5/16" hex nut.
Drive the nut into one end of the copper tube.
Fill your case with water and place upright in the tool. Insert a very close fitting round punch in the top and whack it with a hammer. Out comes the primer. The nut in the bottom holds the case steady and allows the primer to fall out. Nice and easy. You can also use a 5/16" rod or clevis pin etc. For other calibers you would need to find a snug fitting tool of that size.
This process worked great on cases where the primer was not sealed into the case. On those I still have to use the chisel method to remove the primer.
