I have a bunch of 8mm Label machine gun ammo, on strippers.
I'm hoping to turn the brass from berdan to boxer primers.
Never had so much trouble taking out the old primers.
RCBS bedan remover tool.
Mangled a few brass trying.
After looking more closely at one of the primers, I saw that it had two cups.
An outer cup of brass, inner cup of copper, them the priming material.
Don't do many berdan primers, but I've not seen another like it.
