It's not the lack of performance just the lack of actual gun handling experience in the average hunter to handle a super mag. I had five hunters last year show up with 3 308 warbirds and 2 300 rem ultra's. Out of these five men only two could shoot less than a 4 inch groups at 100 yards. In my opinion there are some hunters that shoot enough to handle the recoil and noise. But most would havebeen better off with a 30-06. Its not the gun problem its a people problem. I owned a 378 weatherby and it could shoot clover leaf groups like any other rifle in the closet but at $4 a shot I found someone who wanted more than I did.
