If it turns your shoulder black and blue after 5 shots, you're doing things a little wrong. My .300 isn't a *****cat, by any stretch, but I can shoot a whole box on the bench before I start feeling it. It's still very new to me, so I've only used it on one deer, and I put a perfect shot on her (tucked behind the shoulder) - no meat loss at all. It did put an exit wound 2" in diameter on the backside of the ribcage, though... I think if you hit a shoulder with it, the shoulder will probably be a 50-90% loss.

ETA: that's why my .270 is my deer gun. I'm saving my .300 for a bit bigger animals...
