Fort Scott Munitions Tumble Upon Impact (TUI) 300 AAC Blackout 150gr Solid Copper Spun

The Fort Scott Munitions Tumble Upon Impact (TUI) in 300 AAC Blackout is a match grade rifle cartridge built around a 150 grain Solid Copper Spun (SCS) projectile. Engineered around Fort Scott's patented Tumble Upon Impact design, the solid copper bullet yaws and tumbles upon striking soft tissue, creating wound channels that exceed the bullet's straight-line diameter.

Loaded in a brass case for reliable feeding and corrosion resistance, this lead-free round is well suited for hunters and defensive shooters seeking consistent terminal performance from their 300 BLK rifles. The all-copper construction promotes uniform expansion and high weight retention across a wide velocity range.

Performance out of the muzzle is impressive, with a 1,728 fps velocity producing 995 ft-lbs of energy. Combined with the TUI design, this round delivers rapid, reliable knockdown performance on game and dependable stopping power for defensive applications.

Sold as a 20-round box. Case configuration is 25 boxes per case (500 rounds total).
