LOL, I've blown fist sized holes in deer with 7STW's, 300 Mags and such, and yes, they bolt, I have to believe the high speed bullet impact must spool up the nervous system, they have such an adrenaline dump they bolt.
Have shot all sorts of game with slow Sharps rifles and have had several boom flops, or boom slow walk trot to a fall, I guess a calmer more polite kill if you will? I don't know.
Don't know about any 50 cal AR's save the Beauwolf? cartridge.
