I have a M77 MkII in 270 with the all weather skeleton style stock, personally and most close friends that have shot it agree it kicks like a mule so I have been tossing around the idea of adding weight to it, is there any down side to adding weight other than being able to carry it comfortably? can it damage anything? Does anyone know the basic approximate rifle weight it would be appreciated and how much would be to much weight to add?
