I'd look into getting the heavy'est bullet possible IF! I didn't like what the 300-mag did to deer. I gotta tell you that I love the DRT affect and not having to track the deer and not having it jump fences and having to ask the neighbor if I can track over there.
"Hi guys, my name's mike and I'm a shoulder shooter" As long as I stay away from the back-straps and hind quarters, I'll zip that bullet any way I can through both lungs, and if a shoulder is in the way, it's getting blow'n through.
