Fort Scott Munitions Tumble Upon Impact (TUI) .40 S&W ammunition (brand part no. 400125SCV) fires a 125-grain solid copper spun bullet designed to tumble and fragment through soft tissue on impact. Fort Scott Munitions engineered the TUI line as a monolithic, lead-free alternative to traditional expanding bullets, machined entirely from solid copper rather than jacketed lead. The solid-copper construction favors shooters who want deep, consistent penetration without bullet fragmentation into lead components. In handgun ammunition, this .40 S&W load is built around Fort Scott’s tumble-on-impact terminal design.
