This subsonic 300 Blackout ammo by S&B is a great price point for can-ready ammo! The 200 grain weight combined with a carefully calculated charge of clean-burning powder produces a subsonic muzzle velocity of 1,060 fps from a 16" test barrel for perfect synergy with a suppressor.
The FMJ bullet used possesses a boat tail rear for improved drag resistance as well as a toothed cannelure at its crimp point for stable seating and consistent accuracy. S&B loads the bullets into cases that are brass-cased, Boxer-primed, and reloadable. Sellier & Bellot, a Czech outfit, has been around for almost 200 years and uses their experience to preserve obscure calibers while also keeping up with the latest in manufacturing technology for the benefit of shooters everywhere.
