Buffalo Bore 39B20 Supercharged 308 Win 150gr Barnes Tipped TSX Lead-Free Ammo - 20 Rounds/Box

Buffalo Bore's 39B20 Supercharged 308 Win ammunition pairs serious velocity with a proven lead-free projectile designed for hunters who demand both performance and environmental responsibility. Loaded with a 150-grain Barnes Tipped TSX bullet, this round delivers the speed and energy needed for effective hunting at distance while using a copper-alloy construction that leaves no lead downrange—an advantage whether you're hunting in lead-free zones or simply prefer non-toxic ammunition for your rifle.

The "Supercharged" designation means Buffalo Bore has engineered this load to extract more velocity than standard commercial offerings, pushing the lighter 150-grain bullet to speeds that enhance energy transfer and extend your effective range. The Barnes Tipped TSX design combines the reliability of the all-copper TSX with an aerodynamic polymer tip that improves ballistics and on-game expansion. For 308 Winchester shooters, this is a round that bridges hunting versatility with serious velocity.

Each box contains 20 rounds, making it convenient for range days or hunting trips. Buffalo Bore's commitment to quality control and component selection means you're not just buying ammunition—you're buying rounds engineered for consistent, repeatable performance. Whether you're working up loads for a new rifle, restocking for the season, or testing an ethical, lead-free option, this ammunition represents thoughtful ammunition engineering for the modern rifle hunter.
