Here's a response based on experience with Accubonds.....use the heavier bullet! Accubonds tend to over-fragment over 3000fps. If you hit a bone, you will likely wind up with a shallow wound and could lose the animal. I have found a heavier Accubond at 2850-2950 is very lethal, will perform as designed and is much more likely to exit with a good blood trail, if needed, for recovery. Just my occasionally humble opinion based on several years using the bullets in a variety of calibers.
