It will kill, it might make a mess of some hide if you care.My night hunting/thermal gun is a 223 with a 12.5" barrel and it doesn't like the 77 TMK so I think I'm going to try 55 gr VMAX for wolves.
I've killed piles of coyotes over the years with that bullet so I assume it'll be enough to get through the ribs on a bigger dog. Fingers crossed!
Anybody have any luck this year?
