Using momentum you can get a much better idea about the penetrative potential and make more accurate predictions about real-world performance than you can with KE...

But it's all nitpicky BS to a large extent. We should all just be shooting what we like to shoot, killing stuff and eating it.
note to self: throw away the calculators and get a good chrono.
