+1. Those dogs are amazingly hard to kill. The only way you'd have any chance of killing a coyote with any air gun would be with a brain-penetrating shot through an eyeball from directly in front, and I'm not even too sure about that.There is no way you can ethically or reliably take a yote with your gun. Even the heaviest pellets available will have < 40 foot pound energy (FPE) at the muzzle @ 650 FPS. Not enough to cut the mustard even with a perfect shot. FPE will be less by the time it hits your target. Advertised FPS tend to be with light weight pellets, but heavier pellets are better for hunting.
