Thread: RIFLE PRIMERS

Yes but the anvil is designed to be captured and sits against the back surface of the primer pocket so the priming compound is crushed against it once struck by the firing pin. The 209 cups are deeper than a primer pocket in a brass cartridge so the anvil is not against the end of the pocket. firing pin is likely going to just hammer the LRP deeper into the 209 cup or push the primer compound and anvil out the front of the primer into the void and not ignite.
