The Sig Sauer Elite Performance .308 Winchester 168-grain Open Tip Match (OTM) Brass 20-round box is competition-grade centerfire rifle ammunition engineered specifically for long-range target shooting, tactical marksmanship, and match competition. A primary operational limitation in precision rifle disciplines is point-of-impact shift and horizontal dispersion caused by subtle variations in bullet meplat, jacket concentricity, and velocity spreads. Sig Sauer resolves these precision bottlenecks through its Elite Performance Match line, pairing Sierra's legendary 168-grain MatchKing OTM projectile with match-grade brass and temperature-stable propellants to deliver sub-MOA accuracy and extreme shot-to-shot repeatability.
The core technical advantage relies on the projectile's 168-grain Sierra MatchKing Open Tip Match (OTM) architecture. Engineered with a swaged lead-alloy core enclosed in a precision-drawn copper jacket, the bullet features a tiny meplat opening and an aerodynamic boat-tail base. This structural configuration optimizes the bullet's center of gravity and yields a high ballistic coefficient of 0.462 (G1). By minimizing in-flight aerodynamic drag and crosswind deflection, the MatchKing OTM preserves velocity stability and flat downrange trajectories required for precise target engagement.
Propelling its 168-grain MatchKing bullet at a factory-rated 2,700 FPS muzzle velocity (generating 2,719 ft-lbs of muzzle energy), this Elite Performance loading provides consistent barrel harmonics and clean powder burn. Assembled in Sig Sauer’s precision-drawn reloadable virgin brass cases paired with clean-burning propellants and non-corrosive match Boxer primers, the cartridge guarantees tight velocity standard deviations, uniform chamber pressure, and silky-smooth extraction in bolt-action match rifles and semi-automatic precision platforms.
Key Benefits
- Sierra MatchKing OTM Bullet: Proven 168-grain match projectile delivers extreme concentricity for sub-MOA groupings.
- 0.462 G1 Ballistic Coefficient: Aerodynamic boat-tail profile lowers flight drag and mitigates crosswind drift.
- Tight Velocity Consistency: Premium propellants and primers yield uniform muzzle velocities and flat trajectories.
- Match-Grade Virgin Brass: Precision-drawn reloadable brass cases ensure smooth chambering and consistent neck tension.
