Guide activated cartridges/Piston guide cartridges make use of a guide in the type of a blank to include the propellant within the cartridge, or as a piston to unlock the bolt as well as cycle the weapons operation.

For that factor, Berdan cases have two flash holes on either side of the anvil. The primer itself has no internal anvil, so the compound is pushed against the anvil part of the instance to create ignition. Both kinds are practically reloadable, yet Berdan is an imperial discomfort in the butt.

Those are easy to eliminate from fired situations. As the flash opening remains in the facility, a pin in the resizing die just pushes the invested primer out the base of the situation. Easy peasy.
