I hate it when the entire bullet flies out of my barrel.
Time to bore our barrels to case size and ream our primer pockets so loose that when we fire the primer flies out and pressure is vented from the flash hole....sounds feasible lol :P
Not only feasible, something like that has been done already.
Check out what the 13mm Gyro Jet cartridges did. They had holes in the back around the primer, so the primer stayed in place.
FYI, the hammer on the gun actually hit the front of the cartridge, driving it back into the firing pin which started the ignition process with the primer. The cartridge then fired off and pushed the hammer back down, re-cocking it as it went by on the way out.
Got to love non gun people who try to make money in the gun market.
