I have found about the same percentage of retained weight using ABs in .257, .270, .308, .338, .366 and .375 caliber cartridges on a variety of deer and elk and several species of African plains game. Overall, I have recovered just about half of them. The rest have exited. No failures, although several elk have stood around long enough to take a second shot. I admit to still shooting Partitions in two rifles that shoot them more accurately than anything else I have tried.
