The Sig Sauer Marksman Hunter .308 Winchester 165-grain Hollow Point Boat-Tail (HPBT) load is designed for hunters who refuse to choose between pinpoint accuracy and devastating terminal power. The classic compromise with standard hunting rounds is that you often have to sacrifice aerodynamic precision to get a bullet that expands reliably at longer distances. Sig Sauer eliminates this performance bottleneck by loading the legendary Sierra GameKing HPBT projectile, giving you a match-grade flight profile that delivers hard-hitting, predictable expansion exactly where you aim.
The technical advantage centers on a perfectly balanced external and terminal ballistic design. The Sierra GameKing features a specialized skived jacket with internal scoring around the hollow-point nose, which forces the bullet to peel back into a uniform, devastating mushroom upon impact. This rapid expansion occurs reliably across an incredibly broad velocity window without breaking apart. At the rear, a precision-engineered boat-tail base slices through air resistance, preserving your downrange velocity and significantly flattening your trajectory.
Launching its 165-grain payload at a crisp 2,700 FPS, this round utilizes a high-performance 0.363 G1 ballistic coefficient to shrug off crosswinds and reduce vertical drop. Sig Sauer packs these cartridges with temperature-stable propellants to ensure identical chamber pressures and tight velocity standard deviations, whether you are hunting in freezing mountain ranges or humid bottomlands. Loaded into premium, uniform brass cases, this load delivers the laser-like shot placement and deep, crushing penetration required for clean, ethical harvests on deer, pronghorn, and elk.
