Wilson Combat 300 Blackout ammunition delivers reliable subsonic performance built for shooters who demand precision and consistency. This 220-grain Sierra HPBT load is specifically tailored for 16-inch barrels, achieving 1025 feet per second while staying below the sound barrier—ideal for suppressed rifles, tactical training, and hunting applications where subsonic velocity matters. Every round is manufactured and hand-inspected at Wilson Combat's Berryville, Arkansas facility, giving you the quality control and attention to detail that factory ammo often lacks.
What sets Wilson Combat apart is their commitment to the details that matter downrange. They use clean-burning, low-flash powders that preserve your night vision during evening shooting and reduce fouling in your rifle. Rigid taper crimping and post-manufacture tumble polishing ensure consistent feeding and extraction across different firearms. The result is ammunition that performs reliably whether you're running it through an AR platform, bolt gun, or other 300 Blackout chamber.
Sierra's HPBT bullet is a proven performer, engineered for controlled expansion and deep penetration when it matters. Wilson Combat's loading practices account for barrel length variability—this subsonic load is optimized for 16-inch barrels specifically, so you get the velocity and pressure curve the round was designed for. Whether you're zeroing a new suppressor setup, running precision drills at the range, or hunting with a quiet, flat-shooting platform, this ammunition bridges reliability and performance without compromise.
