Maybe the 45 Colt.
30-06, 308, 223, 50 BMG.....
Maybe they are American, but they are common everywhere.
The most American Cartridge needs to be popular, but only
in America.
Don’t change the GIST of the thread. NO one said ONLY in USA.
The Mausers are known .....
The mmmS are known......
Most American Cartridge does NOT matter WHERE it’s used.
