7X57R Ammo

The 7x57R is the rimmed variant of the 7×57mm Mauser cartridge – ballistically speaking, the two rounds perform identically. The 7x57R was once very popular in Europe, and still remains in production there for use in various double-barrel and single-shot rifles. It’s nearly as powerful as America’s preferred 270 Win, and offers a slight energy advantage over most of the 6.5mm rounds.
