Wow are your wrong. They shattered and left gritty powder in a 10 lb red fox.
Guess we'll have to take your word on that. Got pics. of those reds. with the "powdered" pellet residue? Why not mention the "fact" that you've seen them shatter, first hand, in your first post?
You do have me curious now though since I have some of the dead coyote T shot at the house. I will be opening the crimp on one to test the shot for myself.
