The Discreet Ballistics 300 Blackout 190gr Subsonic Target Load is intended for use in semi-automatic and bolt action firearms chambered in 300 AAC Blackout. This round has been thoroughly tested to function in both pistol and carbine length gas systems. Discreet Ballistics gives its customers the option of choosing these loads for use in 16″ barrels or 7-11” barrels.
300 AAC Blackout is typically chambered in platforms with barrel lengths ranging from 7” to 16”. Until recently, any commercially available ammunition had only been available in one load for each extreme in barrel length. What this means is that 300 Blackout ammunition that is designed to have a muzzle velocity of 1050FPS out of a standard 16” rifle barrel will often have a 900fps or less out of a 7” pistol/SBR barrel. At 100 yards this can result in as much as a 200fps drop making it more difficult for the shooter to get on target. Discreet Ballistics offers its 300 AAC Blackout ammunition in either pistol/SBR (7-11”) or rifle (16”) barrel loads so that velocity is consistently in the 1000fps range no matter which platform the shooter is using.
