No, good question dick. Two caveats, i was actually looking to book a hunt with his outfitter right before he died in australia and asked just that and he told me that the bullets werent in danger of passing thru when hitting bone on the way in and out. Some were not very fast kills and they were cull biffs. Matt had told me that he was getting a 454 with some appropriate bullets since i would have been shooting one or two large trophy buffs. I didnt have the time to cull a bunch in the same way lynn did. That said, no 300 gr 44 mag bullet at 1100 fpshas ever been in danger of exiting on any of the animals at the bovine bash.
