Buffalo Bore Ammunition 55B20 Buffalo-Barnes Strickly Business 300 Win Mag 180 gr Barnes Tipped TSX Lead Free 20 Per Box/ 12 Cs

Buffalo Bore Ammunition's Strictly Business line in 300 Win Mag delivers lead-free performance built for hunters and long-range shooters who demand ethical, environmentally responsible ammunition without compromise. This 55B20 load pairs a 180-grain Barnes Tipped TSX bullet—a monolithic copper projectile engineered for controlled expansion and deep penetration—with a carefully developed powder charge optimized for the 300 Win Mag's magnum case. If you're hunting big game at distance or testing precision loads at the range, this ammunition bridges the gap between ballistic performance and lead-free compliance, whether you're in a state mandate area or simply choosing non-toxic rounds.

The 180-grain bullet weight is the sweet spot for 300 Win Mag—heavy enough to carry velocity and energy downrange, light enough to keep recoil and barrel wear in check compared to heavier magnums. The Barnes Tipped TSX design uses a copper body that fragments predictably on impact while the polycarbonate tip ensures reliable expansion from point-blank to extended distances. Because Buffalo Bore hand-loads each round to exacting standards, you get consistency from box to box—critical for hunters who zero once and expect the same point of impact every season.

Each box contains 20 rounds, and this listing is for a full case of 12 boxes (240 rounds total). Buffalo Bore's reputation rests on quality control and accuracy that matches custom handloading at factory price points. If you shoot a 300 Win Mag for hunting, precision rifle competition, or long-range field work and want ammunition that performs while respecting lead-free regulations, Strictly Business is a serious choice.
