If you're buddy is that experienced and killed that many cats, I'm suprised he doesn't pull back and tether his hounds for the money shot. On archery hunts, we've always gave cats a "back door" just in case it gets ugly. FWIW, I've never seen a wounded cat stick around and fight when retreat is an option??
I would agree that many can't shoot a pistol all that well. But there's just as many that can't shoot a rifle all that well either (unless they've got a concrete bench and a Lead Sled)
I'm sticking with Vomit Proof finishes though
