The Fort Scott Munitions .300 Blackout 150gr TUI load is a box of 20 rounds of non-lead solid copper spun SCS ammunition. Fort Scott builds this load around a CNC-machined bullet with its patented Tumble Upon Impact design. Rather than relying on expansion, the bullet is designed to tumble end over end when it meets water-based tissue. The listed velocity is 1728 fps through a 16-inch test barrel. Fort Scott markets it for hunting, match shooting and self-defense.

Frequently Asked Questions

Does this load contain lead? No. Fort Scott lists the bullet as non-lead solid copper.

How many rounds are in the box? The box holds 20 rounds.

Does Fort Scott give any prep or handling guidance for this ammunition? Fort Scott recommends cleaning your barrel thoroughly before shooting solid copper or brass if you have been shooting other ammunition, since a clean barrel improves accuracy and performance with solid monolithic ammunition. It also notes that repeatedly cycling an unfired cartridge can cause the projectile crimp to fail and the bullet to loosen, more often with larger monolithic projectiles. For AR10 platforms that are not mil-spec, Fort Scott recommends polishing the feed ramp before use and checking the headspace of your firearm.
