Buffalo Bore’s Outdoorsman Strictly Business ammunition in 10mm Auto (brand part no. 21C20) loads a heavy 220-grain hard cast flat nose bullet built for backcountry carry, not the range. Buffalo Bore builds this loading around maximum firepower for hikers, hunters, and guides who need a sidearm capable of stopping something considerably larger than a human attacker. The hard cast flat nose does not expand; instead it drives straight through muscle and heavy bone in a flat, unyielding line, the exact penetration profile wilderness-defense handgunners want when a hollow point’s shallower path is a liability rather than an asset. For 10mm owners who carry in bear or hog country, this handgun ammunition is built for the worst-case encounter.
