About Tumble Upon Impact®

Fort Scott Munitions’® monolithic, solid copper projectiles are specially engineered to tumble when striking water-based tissue. This Tumble Upon Impact® TUI® design ensures that the distribution of damage primarily occurs internally instead of at first contact with skin.

Bullet travels straight through skin into vital organ area.

Once hitting the water-based tissue, the bullet begins to tumble.

The bullet has rotated 180 degrees causing extreme wound cavities.

TUI® ammo tumbles cutting through everything in its path causing extensive damage.
