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.
