The Buffalo Bore Ammunition 37B20 Heavy Strictly Business .327 Federal Magnum 130gr Hard Cast load is built for shooters who need serious penetration from a compact revolver cartridge. Using a 130-grain hard cast Keith-style bullet over flash-suppressed powder, this Heavy 327 Federal round delivers full-power performance while remaining safe in all-steel revolvers and standard pistols.

This ammunition is tailored for demanding outdoor use where deep, straight-line penetration is preferred over expansion, making it well suited for hunting, predator defense, and backcountry carry. The reduced muzzle flash helps maintain visibility in low-light conditions, and brass, boxer-primed cases offer reliable function and the option to reload. Buffalo Bore’s attention to detail and commitment to powerful, dependable handgun loads is evident in every round.
