2.5 year old smaller black bear. That is a Ruger Hawkeye African in .416 Ruger laying across him. I hit him with a 340 grain woodleigh weldcore loaded "down" to 2,550 fps. He didn't go anywhere. Softball sized exit. The bear in my avatar was about 180 lbs on the paw and he was hit with a .375 H&H loaded with Hornady 300 grain interlocks at 2,550 fps. He also didn't go anywhere. Surprisingly... both bullets were pass throughs.
