I'm another in the camp of desiring/demanding an exit. You can not depend on any load making an animal drop on the spot unless you break the spine. If he moves off, a blood trail is very nice to have.
But, if it can break both shoulders, then I see no problem. I mean, where is the critter going to go ? He'd have to push himself with his hind legs which isn't going to move him very far or very fast.
I like my bullets to exit, or break at leat one shoulder and penetrte the chest. Or shoot diagonially, hip to shoulder through to the vitals.
It's pretty clear this bullet is up to the job. I've used them myself in the .308 on deer. The latest designs both shoot better at targets and at the longer ranges. E
