Fort Scott Munitions Tumble Upon Impact Features The Fort Scott Munitions TUI load uses a multi-patented Tumble Upon Impact design where the solid copper spun bullet begins tumbling immediately after striking its target. This tumbling action creates a wound channel far more damaging than a bullet that simply expands or stays on a straight path giving the 80 grain projectile devastating internal effect. Because the bullet is a solid copper design rather than a jacketed lead core it holds together through barriers and heavy clothing without fragmenting or losing mass. At 1564 fps out of the muzzle this 9mm +P load delivers the added velocity a +P round is meant to provide for defensive applications. Each bullet is machined from premium copper on precision CNC lathes giving Fort Scott Munitions tight manufacturing tolerances and consistent bullet weight from round to round. Being completely lead free this ammunition is well suited to ranges and hunting areas with lead restrictions while still delivering serious terminal performance. The brass cased boxer primed construction keeps this load compatible with standard 9mm firearms without any special modification. For shooters and hunters who want a non-lead defensive round with proven penetration and tumbling terminal performance this Fort Scott Munitions TUI load is a strong choice.
