Fort ScottA(R) TUIA(R) (Tumble Upon Impact) Ammo features a solid copper bullet that penetrates like a standard FMJ projectile-but tumbles end-over-end when it comes into contact with tissue, creating a devastating wound channel. And unlike hollow points that can bounce off of tough hide, this Solid Copper Spun bullet cuts right through tough hide to cause maximum damage. So you get all of the benefits of a hollow point AND a full metal jacket round, in one. Fort Scott Ammo is made in America in small batches to deliver a finished product of the highest quality. Every bullet is machined from solid copper on a CNC lathe to extremely tight tolerances, and each case is coated in Black-TPDA(R). Black-TPD combines the reloadability and lubricity of nickel with unsurpassed corrosion resistance-so it's basically impervious to moisture, and it feeds as smooth as silk. We don't find many new ammo manufacturers that impress us, but Fort Scott TUI is impressive stuff that does exactly what it says. Muzzle velocity is tested in a 4" barrel with 1:10" twist.
