The numbers make it obvious it’s flatter shooting than the subsonic load. Lack of wind drift alone is a decided advantage, along with a flatter trajectory. Planes that increase their velocity until it reaches and exceeds that mark generates a sonic boom. Results are in inches/foot-pounds of energy and based on a 100-yard zero with the scope 1.5 inches above the bore.

If downrange energy is a critical consideration, the last yardage that still carries at least 400-foot-pounds is italicized. Suppressors minimize the chances of a sniper being located by sound, but they simply reduce audible emissions from their firearm’s muzzle end, not a projectile’s characteristic “crack.” To avoid it from giving a shooter’s position, subsonic .300 BLK loads use heavier bullets and adjusted powder charges—often tailored for a complete burn in a short barrel.
