Berdan and Boxer cartridge primers are both considered "centerfire" and are not interchangeable at the primer level; however, the same weapon can fire either Berdan- or Boxer-primed cartridges if the overall dimensions are the same. An early form of centerfire ammunition, without a percussion cap, was invented between 1808 and 1812 by Jean Samuel Pauly. This was also the first fully integrated cartridge and used a form of obturation employing the cartridge itself. This system worked well, allowing the option of installing a cap just before use of the propellant-loaded cartridge, as well as permitting reloading the cartridge for reuse. In the end of the cartridge beneath the primer cap was a small vent-hole, as well as a small teat-like projection or point (this was to be known as an anvil later on) fashioned from the case, such that the firing pin could crush the primer against the anvil and ignite the propellant.

Place them in small container. Rubber conducts heat well and retains heat, so the tires have a very small amount of rubber on them to avoid heat build-up.
