A 300 AAC Blackout SBR with a suppressor is one of the most useful tools you could keep handy for home defense. If you say the same thing – and you practice what you preach – then you’ll love Hornady’s Subsonic series 300 BLK ammunition.

Naturally, this is a subsonic load. Its heavy 190 grain bullet exits Hornady’s 16” test barrel at a rate of 1,050 fps, so you won’t have to worry about getting deafened by a sharp, cracking report when you fire within the confines of your own home.

This round’s Sub-X bullet is specially engineered to deliver reliable terminal expansion following subsonic impact. Like Hornady’s XTP projectile, the Sub-X features a polymer Flex Tip that facilitates expansion at lower velocities. Its notched jacket and flat nose profile do even more to facilitate clockwork expansion. More damage to the target, accompanied by less risk of overpenetration. Spot on terminal ballistics for defensive applications, and not unsuitable for hunting, either.

This ammo’s new reloadable brass cases contain low-flash propellant. It’s formulated to emit less muzzle flash upon ignition, so you’ll be able to continue seeing in the dark after firing your initial shot. Ask any self-defense expert: being able to see the threat is important during any self-defense situation.
