I recently witnessed a rather large black bear shot 3 times with a Ruger 375 using factory Hornady 270g (I think) interlocks. 1 Bullet hit the backbone and pelvis. There were bullet fragments everywhere through the wound channel. Another was a lung shot without pass through. This bullet was a perfect mushroom found in the hide. The last hit the front shoulder and the bullet and core were found separated on the hide and in the hide again.
The bullets were accurate, and the bear is dead. I did not like the grenade affect of the bullets though. Is this normal for this bullet?
