I am guessing not... Dober put one out of a .22-250 almost lengthwise through a 7 foot bear....and he is one of few whose opinions I trust. It was a fave of his for deer, and I don't see why not. I was shooting them in a 1 in 8 twist, but not pushing them too hard...about 2900 fps. Shots were 75-100 yards.
