Rookie primer question: berdan or boxer
A friend of mine asked me what the difference between Berden primers and boxer and I do not know. Anyone care to enlighten a fellow gun nut :)

Here's a link Collecting and Shooting the Military Surplus Rifle (2005) -

Excellent and detailed link Dunner. It explains the two in greater detail and has pictures too, ChuckD. :)

Simple explanation:

"Boxer" primers are the most commonly used commercial priming system. The primers itself has a cup and "anvil" and the primer pocket in the case has one flash hole in the center of the pocket. This makes it easy to punch out the old primer with a simple pin punch.

"Berdan" primers do not use the "anvil", it is formed into the case head and thus there are two flash holes on either side of the anvil. This makes the Berdan much harder to reload.

And, in a strange twist of fate, the Boxer primer, used throughout the US, was invented in Europe. The Berdan system, used throughout Europe, was invented in the US.
