## Abstract

We amend 50 CFR 20.21(j) to approve shot formulated of 50% tungsten, 35% nickel, and 15% iron as nontoxic for hunting waterfowl and coots. We assessed possible effects of the tungsten-nickel-iron (TNI) shot, and we believe that it is not a significant threat to wildlife or their habitats and that further testing of the shot is not necessary. In addition, approval of TNI shot may induce more waterfowl hunters to switch away from illegal use of lead shot, reducing lead risks to species and habitats.
