Well I have done wet decapping and the rcbs tool method too.
Wet decapping, I made up a threaded die out of a chamber stubb.
Fill case with water, insert into press, position piston above die, wack with mallet.
I found that some military glued in and staked primers won't budge using the wet method.
Rcbs tool method.
The tool pries out the primer.
I made up a bunch of pins using those hard concrete nails because you will break the rcbs pins.
Either way I used tula berdan primers.
Bought a whole case of the size for x39 and 762x54.
Also used them for crap fn 7x57 which I salvaged the bullet and case but primers were bad.
Too lazy to do any now that the panic is over and nearly any brass can be purchased.
Do not try reloading Albainian brass x54r.
Stuff is too brittle.
Yugo x39 brass is great stuff though.
I have not tried the new method posted.
It should work though.
