300 AAC Blackout Subsonic Practice loads use heavier bullets, typically 190–220 grains, at velocities below the speed of sound to eliminate the supersonic crack. These loads are commonly used with suppressors, for quiet range training, and for shooters who want to practice with the recoil profile of subsonic ammunition. Pricing typically runs higher than supersonic practice loads due to heavier projectiles and smaller production volumes. The products listed above include dedicated subsonic lines from major manufacturers, so daily price movement reflects the niche subsonic retail market.
