The 300 Blackout cartridge was designed for suppressed use at a target shooting range. While some 300 BLK ammunition is supersonic and capable of hunting, this caliber is best used with subsonic projectiles. The Sellier and Bellot .300 Blackout ammo utilizes a heavy 200 grain bullet to keep it from breaking the sound barrier when shot to keep it as quiet as possible out of a suppressed rifle or 300 BLK pistol. The long subsonic 300 AAC Blackout FMJ projectile offers reliable performance out of short to long barrels and either semi-automatic or bolt action platforms. The reloadable brass cases and affordable price allow you to shoot all weekend while saving money on your next trip to the range. If you are looking for the quietest subsonic ammo without sacrificing reliability, the Sellier & Bellot 200gr 30 caliber target ammunition is for you.
