Sig Sauer Elite Performance Match Grade 300 AAC Blackout Subsonic 220 Grain OTM Ammunition

Sig Sauer Elite Performance Match Grade 300 AAC Blackout subsonic ammunition is built for shooters who demand precision from a suppressed rifle. Loaded to subsonic velocities with a 220-grain Sierra MatchKing open-tip match (OTM) bullet, this is serious ammunition for accuracy-focused shooters running 300 Blackout suppressed builds. Whether you're shooting an integrally suppressed rifle, a can-equipped AR, or testing a precision subsonic load, these rounds are engineered for minimal velocity spread and tight shot groups.

Sig Sauer's Elite Match line uses precision electromechanical loading processes to ensure geometric consistency round after round—no guesswork, no wide velocity windows. The Sierra MatchKing bullet is a proven design in match-grade ammunition, known for clean flight characteristics and predictable expansion at subsonic speeds. Brass cases and OTM construction keep things consistent for reloaders, too.

This is the ammunition choice when you're zeroing a suppressed subsonic rifle, loading for a PRS match, or simply refusing to settle for mediocre ammo. At 300 Blackout subsonic speeds, every variable matters, and Sig Sauer has engineered this load to control the ones it can. Each box contains 20 rounds, ready to load and shoot.

Frequently Asked Questions

Is this ammunition subsonic, and will it work with my suppressor?

Yes. This load is specifically loaded to subsonic velocities, making it ideal for use with a suppressed rifle. Subsonic ammunition produces minimal supersonic crack, letting your suppressor do its job effectively.

What is OTM ammunition, and is it reloadable?

OTM stands for open-tip match—the bullet has a hollow tip instead of a closed point, designed for precision and consistency. These rounds use brass cases, making them suitable for reloading if you reload ammunition.

Will this work in my 300 Blackout AR rifle?

This ammunition is loaded for a 16-inch test barrel. Compatibility depends on your specific rifle's chamber and overall setup. We recommend checking your rifle's manual or consulting with a gunsmith if you have questions about chamber specifications.
