.300 AAC Blackout Ammo Prices

Built in 2011 to feed relatively low-velocity .30-caliber bullets through a standard AR-15 with nothing changed but the barrel. The caliber lives a double life: light supersonic loads around 110 to 125 grain for general work, and heavy 190 to 220 grain subsonics that make it the suppressor world's darling.

The .300 Blackout reaches its maximum velocity in shorter barrel lengths than 5.56. This gives the .300 its maximum performance in a suppressor-friendly pistol or SBR platform. As usual, 1000 round case buys save money.
