Fort Scott Munitions Tumble Upon Impact (TUI) Features The Fort Scott Munitions TUI load in .308 Win is built around a solid copper 165 grain projectile specifically engineered to tumble upon striking water-based tissue. This tumbling behavior ensures damage is distributed internally along the wound channel rather than concentrated at the point of impact a departure from how a standard expanding bullet performs. Because the bullet contains no lead the load is a cleaner-burning option for hunters and shooters concerned about lead fragmentation. A muzzle velocity of 2607 fps keeps trajectories flat and delivers consistent downrange energy for medium and big game hunting. Each round is assembled on a brass case supporting smooth feeding and reliable extraction across bolt action and semi-automatic .308 Win rifles alike. The 20-round box is a practical size for range sessions load testing or filling out a hunting trip s ammunition supply. Fort Scott Munitions monolithic bullet construction reflects a commitment to terminal performance without relying on lead-based projectiles. Hunters and shooters looking for a dependable lead free rifle round will find the Fort Scott Munitions TUI .308 Win a strong choice.
