The Sig Sauer Match Supersonic .300 Blackout 125gr OTM ammunition in a 500-round case delivers high-volume precision performance for serious shooters, competitive marksmen, and tactical enthusiasts who run .300 BLK platforms extensively. This bulk case—typically comprising 25 boxes of 20 rounds each—provides the same elite match-grade consistency as individual boxes, featuring a 125-grain Open Tip Match bullet optimized for superior accuracy, tight groupings, and minimal dispersion even when using suppressors. With supersonic velocities around 2,200 fps, it offers a flatter trajectory than subsonic loads, excellent energy retention for distances out to 300 yards, and reliable cycling in AR-15 style rifles without the need for magazine modifications.
Built with premium brass casings, high-quality primers, and clean-burning propellants under Sig Sauer's rigorous standards, this ammunition ensures shot-to-shot uniformity, reduced fouling, and flawless function during prolonged range sessions or multi-stage competitions. The OTM design emphasizes aerodynamic stability and low recoil for faster follow-ups and enhanced control, making it a preferred choice for PRS-style events in .300 Blackout, precision training, varmint hunting, or building suppressor-optimized setups where accuracy and consistency are non-negotiable. Bulk packaging streamlines stocking for high-round-count days, allowing shooters to focus on performance rather than frequent re-supply.
This 500-round case is ideal for dedicated .300 BLK users preparing for competitions, honing long-range skills, or conducting tactical drills where match-level precision in a versatile caliber makes all the difference. American-made and engineered for demanding applications, it combines supersonic speed with the reliability and accuracy that SIG shooters trust across platforms.
