The Browning BXS .308 Winchester 150-grain Solid Expansion Polymer Tip 20-round box is a high-performance centerfire rifle cartridge engineered specifically for big game hunting where extreme weight retention, deep straight-line penetration, and lead-free compliance are paramount. A standard frustration point with traditional lead-core big game bullets is jacket-core separation or fragment breakup when striking heavy bone, drastically reducing penetration depth and compromising terminal effectiveness. Browning completely overcomes this vulnerability by using a monolithic solid copper projectile that maintains structural integrity, resists shedding mass, and drives straight through dense muscle tissue and thick bone.
The core mechanical advantage focuses on high structural integrity combined with rapid, positive expansion. Featuring a 0.415 G1 ballistic coefficient, the 150-grain solid copper projectile maintains velocity, resists wind drift, and flattens trajectory over extended distances for precise shot execution. Upon target impact, the polymer tip acts as a hydraulic wedge, forcing energy backward into the engineered hollow cavity to initiate rapid, mushrooming expansion. Because the body is constructed entirely of high-strength copper, the bullet avoids fragmentation, holding nearly 100% of its initial mass to deliver massive hydrostatic shock and deep penetration through tough vitals.
Exiting the muzzle at 2,820 FPS, this specialized .308 Winchester cartridge delivers predictable downrange speed and flat trajectories across varied environmental conditions. The load is built with nickel-plated brass casings that drastically reduce chamber friction, preventing binding, sticky extraction, or feed-ramp hangups in bolt-action and semi-automatic rifles. Complete with clean-burning, progressive propellants and non-corrosive Boxer primers, the Browning BXS series delivers repeatable ballistic precision and corrosion resistance for demanding big game hunts.
Key Benefits
