brass is soft and malleable, resistant to heat and stress.... steel is not.... well mainly the flexible part. a shell must be re-sized before you can reload it.

also... some manufacturers make rounds with a "boxer Primer" and some make them with "berdan primers".... its a little inaccurate because the primer is the same but one case has 2 holes, where the primers is and some have only one in the middle. the berdan primer i believe is the one with 2 holes....


funny thing is, is that one was a European design and one was an American design. we, in America use the European design, and vice versa.


when you remove a spent primer from a case, you use a die with a punch in the center to knock out the primer..... you cant do that with 2 holes that are offset.

There is aluminum cases.
