Try shooting an elk or moose through the shoulder with a 130gr Ballistic Tip out of a 270win or 270WSM, and tell me how you make out. My favorite bullet for deer,pronghorn and bighorn is the 140gr Ballistic Tip out of my 7mmstw, but I would not use that bullet on elk or moose, unless I was presented with a perfect broadside heart/lung shot. On the other hand, the 140gr TSX/TTSX easily penetrates both shoulders of an elk or moose if required.
