I'd be very interested in seeing your science as it contradicts pretty well everything I've read on terminal bullet performance. I'm not saying you are using a bad bullet or that it doesn't kill or hang up on the far hide, I just don't think you fully understand the dynamics of a bullet passing through an animal but I'd be keen to read the science you are basing your theory on.

Use what shoots and performs well and in North America, bullet choice likely makes very little difference but when you start shooting very large game or extreme ranges, understanding terminal performance is very important.
