Revolutionary Tin Projectile:

Our revolutionary TKO® (Tin KnockOut) shotgun sabot is the world’s first lead-free slug designed for use in both smoothbore and rifled barrels, using any choke.
After years of painstaking R&D, we’ve created a 12 GA projectile made of tin - yes, tin - that provides outstanding penetration, stopping power, accuracy, velocity and energy (2607 ft. lbs at 2001 fps), yet is completely safe for you and other living creatures.

Unless you’re a bad guy.
