How do you remove the primer from a bullet?
The term is cartridge- that is a cartridge case, powder, primer,
and bullet (that's the part that comes out of the barrel) It is
extremely dangerous to attempt to remove a live primer from a
loaded cartridge. Once the primer has been fired, reloaders use a
tool called a deprimer to push the old primer out from the inside-
but pushing on a LIVE primer will almost certainly make it fire.
Very unsafe, please do not fool with that.
