This video conducts a ballistic gel test of various 300 Blackout subsonic ammunition loads fired from a 7.5-inch barrel with a 1:5 twist rate. The presenter, Justin from Cerebral Farms, evaluates penetration, expansion, and cavity formation for rounds from Phantom Defense (110gr Rowdy Boy, 85gr Spicy Boy, 220gr Big Brother), Hornady, Nautilus, and Veo. The testing aims to determine the most effective subsonic round for home defense, with a surprising conclusion favoring lighter, faster projectiles.
