I agree 100 % with Ed,,,,, Predators certainly do make a difference on such tough critters. Mike is correct as well with shooting for the hollow area around the eye socket,,, gives an unimpeded path to the brain.
Those predators really are amazing pellets when it comes to penetration through thick hide and bone...
Glad you got your "raider" though,,,, I'm still trying to get the coon that's raiding my garbage cans. Almost got him this morning at 2 a.m. but he was a bit to quick and got away. Gonna try again tonight.....
