The bedded Bulls that I have killed, seen killed and helped haul out have either stood or tried to stand after the first shot. Typically they received extra bullets to help them stay put.

A good Marine marksman with 300 Win Mag took out lungs, piece of heart and broke the off side shoulder and the average size bull covered 60+ yards in deep snow before the finisher from my 300 Wby broke its back. The bull was within 100 yards of the public private line so I couldn't let it keep walking. He thought he might have missed and that I should tag it until we cut him up and saw the fatal shot he had put in the bull.

Deer have all laid their heads down for me.
