Fort Scott Munitions Tumble Upon Impact (TUI) 223 Rem 55 gr Solid Copper Spun - Box or Case

The Fort Scott Munitions Tumble Upon Impact (TUI) line is built around a patented, multi-purpose projectile that delivers match-grade accuracy alongside devastating terminal performance. This 223 Rem loading drives a 55 gr Solid Copper Spun (SCS) bullet out of the muzzle at 3211 fps, generating 1259 ft lbs of energy, with flat trajectories and deep penetration from a monolithic copper bullet that is lead-free and compliant for use where traditional lead-core projectiles are restricted.

What separates TUI from conventional rifle ammunition is the way the bullet behaves after it strikes soft tissue. The solid copper projectile is engineered to tumble upon impact, creating a permanent wound channel that is far larger than the bullet's caliber would suggest while still maintaining the structural integrity needed for consistent penetration. Because the bullet is solid copper with no jacket to separate, weight retention stays consistent shot after shot, and the same load works equally well for defensive rifle applications and hunting.

Each round is loaded in a boxer-primed brass case for reliable ignition and reloadability for handloaders. The tight dimensional tolerances and premium components give this load the kind of group sizes Fort Scott Munitions is known for. The 55 gr TUI is a natural fit for rifles chambered in 223 Rem, pairing high velocity with the flat-shooting characteristics that have made the cartridge a staple of American rifle shooting.
