Fishblade, that poor bullet has taken more flack from people than any other bullet. I can't believe it. What I have found out if most of the poeple clammering about failures are ones who just read about them or heard it at the gunshop. Its rather shameful. My good friend went to africa and took down everything he aim'd at with 300win mag and 165gr BT from monkeys, to kudu. I have taken dozens of deer thru shoulders and briskets recovering them all. I like trying different bullets, so I am in the gameking stage of life for deer, slowly moving to the accubond right now. I have been thru the partition stage (and still am for moose), the BT stage, and hornady stage. All I can say, is don't overthink this stuff. It makes very little to no difference. Sure fun to talk about, but if you put a 165gr something in the lungs/heart of a deer/antelope, you should definately find him. Looking for the magic bullet that has 100% wieght retention, expands from 1500fps to 4000fps to 2.5 times its diameter and drops deer/elk on sight is just silly. These are amazing animals and do some amazing things.
