I have the M77 mark II (walnut stock)in .257 roberts and with factory ammo I've never been able to attain real tight groups, but I've also taken quite a few deer and even a fall turkey with this gun soI have no real complaints. I love this caliber for deer and whenI get into re-loading I figure I can get tighter groups. I've shot core-lokts (117 gr)and federal nosler partitions (120gr) and they both group around ~2" @100yards.

No knees, I'm curious about what you said about the stock. If I hold the forend of the stock in my palm and place my thumb against the barel and put pressure on the barel, the stock will move slightly and make a creaking noise. Should i do what you have suggested? Thanks.
