"295grain hollow point powerbelt"
not that the bullet would stop the groan. But do yourself a favor and quit using PowerBelts. In my experience 90% of the time they will not pass through. So the lack of blood is an issue. Sure there is blood at the point of impact but a blood trail is just not there.
Many will disagree with me. But trust me I have been at this long enough and have had to trail many deer with my dogs and for the most part PowerBelts are the main culprit. Not only powerbelts all ballistic tip bullets.
