Fort Scott Munitions Tumble Upon Impact Features The Fort Scott Munitions Tumble Upon Impact round is built around a solid copper lead free 70 grain projectile engineered to tumble dramatically upon striking a target transferring energy quickly for effective terminal performance. This solid copper construction eliminates the fragmentation and lead exposure concerns associated with traditional jacketed bullets making it a popular choice for shooters who want environmentally conscious ammunition without sacrificing performance. At a muzzle velocity of 2874 feet per second the 70 grain projectile maintains a flat trajectory that helps with accurate shot placement at various distances. This combination of velocity and tumbling design gives the TUI line a distinct terminal performance profile compared to standard FMJ or soft point rifle ammunition. Each round is loaded in reliable brass casing which supports smooth feeding and extraction across a wide range of 5.56mm chambered rifles. Packaged 20 rounds to a box this ammunition is well suited for range training duty use or situations where lead free ammunition is specifically required or preferred. The solid copper bullet construction also means less barrel fouling from lead residue compared to traditional lead core projectiles. Fort Scott Munitions has built a reputation on producing dependable lead free rifle ammunition and the Tumble Upon Impact line continues that tradition with consistent velocity and terminal performance shot after shot.
