The Fort Scott Munitions 450BM-250-SCV product utilizes TUI (Tumble Upon Impact) ammo, a match-grade bullet consisting entirely of solid copper. This design enables it to offer incredible stopping power by tumbling upon impact, hence the name.While this product is primarily designed to cater to the needs of precision-oriented rifle hunters, its multiplicity of proprietary TUI technology patents allows it to function brilliantly in a variety of other scenarios. The firm stopping ability of these rounds makes them equally applicable for use in personal and home defense situations as well as law enforcement fields.
