Black Hills produces factory new rifle ammunition equal to some of the best handloads. It is quickly becoming one of most popular manufacturers of ammunition. Used primarily by all branches of the United State military, this ammunition is also used by competitive shooters and hunters. Loaded with Triple-Shocks, these revolutionary bullets from Barnes are made of 100% copper and contain no lead. When the bullet expands, four razor-sharp cutting petals are created, allowing the bullet to penetrate farther through tough bone and tissue. Triple-Shock bullets usually retain 100% of their original weight, making them a superb choice for hunting. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
