Description
The Fort Scott Munitions TUI (Tumble Upon Impact) line is a match-grade .357 Magnum self-defense load built around a patented Solid Copper Spun (SCS) projectile engineered to tumble upon impact and produce a dynamic, deeply penetrating wound cavity. This 125 gr solid copper bullet is lead-free and topped with a small flat point for consistent expansion and accuracy across a range of defensive platforms.
Loaded in brass cases, this 357 Mag round produces a muzzle velocity of 1424 fps and muzzle energy of 562 ft lbs, giving defensive shooters a hard-hitting, barrier-friendly option for home defense. The solid copper spun construction delivers excellent penetration with devastating internal disruption and is purpose-built for personal protection applications where reliable terminal performance matters.
