Discreet Ballistics offers its 300 AAC Blackout ammunition in either pistol/SBR (5-11”) or rifle (16”) barrel loads so that velocity is consistently in the 1000fps range no matter which platform the shooter is using.ĭiscreet Ballistics designed this target round as part of a premium two load system that complements the Discreet Ballistics 300 AAC Blackout Hunting/SD system which utilizes a machined copper projectile (Selous bullet).

At 100 yards this can result in as much as a 200fps drop making it more difficult for the shooter to get on target. 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 5” pistol/SBR barrel. Until recently, any commercially available ammunition had only been available in one load for each extreme in barrel length. Typically, subsonic loads feature heavy bullets-200 grains and heavier-loaded to velocities below 1,080 fps. In short a good expanding supersonic 300BLK is always ballistically superior to a good expanding subsonic 300BLK. Discreet Ballistics gives its customers the option of choosing these loads for use in 16″ barrels or 5-11” barrels.ģ00 AAC Blackout is typically chambered in platforms with barrel lengths ranging from 5” to 16”. This round has been thoroughly tested to function in both pistol and carbine length gas systems.

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.
