No reason it wouldn't work. The 158 XTP is a good bullet. But I'd still limit the range to around 50 yards to ensure a better hit and humane kill. It's starting to lose a lot of pep at 100 and will may be outside of the 158s design envelope to provide enough penetration/expansion. Thus, the idea of a slightly lighter bullet to retain higher velocity or a cast bullet that is better at penetration.
