So with my airforce lss cf. 457 I have taken 2 deer and to black bear with a 349 gr hp hand cast out of a lynman devastor mold pure lead. All slugs have exited the animals. Deer head shot at 30 yards in the brain. Both black bear at 51 yards #1 in the lungs 1 7/8 hole through both lungs and out the other side went 30 yards. #2 last Friday went through both shoulders looks like the hp was taken off and shank continued on out the other side. The arteries going to the hart was shredded hart was not damaged. And both lungs had a hole through them about 1/2 inch in diameter just in to the front edge.so barely got the lungs. Went 15 yards. Just thought I'd share the experience with everyone. To see real world results.
