Rifle shooter Magizine did a field test on the new 6.8SPC and hunted some mule deer and elk with it. , the bullet they used was the 110grV-max bullet. Hornady's Wayne Holt said "the 110gr V-max bullet should do at least as much damage as an arrow" They did kill a mule deed with it.
Personaly I would say NO , that the bullet could blow up to fast and not get into the viatals if you hit any dense meat or bone.
I coulden't believe that anybody that works for Honady would say such a thing especialy when they will not reccommend that you use a 168gr A-max for deer out of a 308 win. Anybody that would make such a statement obvously doesen't bow hunt or know the differance betwen how an arrow kill and how a bullet kills , that like trying to compair apples to scopes !!!
