Yes I agree coyotes are tough, they have a hell of a tenacity for living.
The biggest coyote I ever killed was a 60 pound male, I thought he was big but 105 pounder would be a giant.
The thing that got me was the amount of time that elapsed from when I shot that coyote and when I loaded him in the truck, when I loaded him he was still as limp as dish rag.
However by the time I got home things changed and it sure was an eye opening experience.
I'm glad that when I loaded him his head was toward the cab and not back by the tail gate.
I'll bet the V-Max bullets will be fine. I'm now using 55 gr JHP bullets for my 223 rifles and I've had no problems with them.
