I have around 450 rounds of 7.63 Tokarev I've had laying around for the better part of 45 years that I'd like to shoot in my old Mauser broomhandle but have always been afraid to (well, after the first 50 shots). I used the "hammer" the other day to pull the bullet out of one of these to get the measurements and just see what was in there. Thought I was going to break my plastic hammer before that crimped in bullet came out. From that it was pretty obvious that I'd use up a case or so of inertial bullet pulling hammers to disassemble all 450 rounds.
Found a tip over on "Cast Boolits" for an easy way to decap berdan primed cases that I'll repeat: First drill a hole a bit larger than the primer in a wood block. Put the case with the primer centered over the hole. Fill the case with water from an eyedroper. Put a bullet sized brass rod in the case mouth and tap smartly with a small hammer. The primer will pop right out from the hydraulic pressure. Slick!! Drill out the built in anvil and it's ready to reload (after it's dry again).
Again, Many Thanks.
