Description
The Fort Scott Munitions Tumble Upon Impact (TUI) line is built around the patented Solid Copper Spun (SCS) bullet – a monolithic copper projectile engineered to tumble upon impact, creating a devastating wound channel without relying on expansion. This 243 Win loading drives an 80 gr solid copper bullet at a scorching 3479 fps, generating 2150 ft lbs of muzzle energy for flat trajectory and hard-hitting terminal performance.
Marketed for home defense, this round is equally at home in the varmint or predator fields thanks to match-grade accuracy, repeatable loaded ballistics, and lead-free monolithic copper construction that’s safe to shoot in areas with traditional bullet restrictions. The brass case delivers reliable feeding and extraction and is fully reloadable, while the precision-spun SCS projectile produces consistent downrange results round after round.
Whether you reach for it as a defensive rifle load or a high-performance hunting cartridge, this 243 Win TUI offering brings the same multi-patented tumbling technology trusted by Fort Scott Munitions hunters, competitors, and defenders.
