Sellier & Bellot 300 Blackout 200gr FMJ Subsonic – 20 Rounds

Sellier & Bellot's 300 Blackout subsonic load delivers reliable cycling in suppressed and unsuppressed rifles with a 200-grain full metal jacket bullet optimized for quiet operation. Engineered to remain below the sound barrier, this load minimizes sonic crack while maintaining effective terminal performance at close to medium ranges — ideal for suppressed carbines, training, and hog hunting where reduced noise signature matters.

Loaded with reloadable brass cases and non-corrosive Boxer primers, this ammunition functions reliably in AR-15 platforms chambered in 300 Blackout with pistol-length to carbine-length gas systems. Available in 20-round boxes or 1,000-round cases for range work and extended shooting sessions.
