Went to wring out the new10/22 today, noticed I couldn't run a dollar bill down the barrel channel but I gave the stock screw just a little snuggy (1/32turn). I dialed in the scope and managed to put one 5 shot string in to a dime at25yrds ( bench rested I'm not that good)then spent the rest of the time chasing mygroups. Finally dawns on me there's movement between the stockand trigger group, the stock screw worked loose. tighten it up and zero goes way the hell off,loosen it up and its different again,but the action moves in the stock as I increase trigger pressure.(duh!) I 'pretty sure I need to be able to pass some paper all theway along between the stock and barrel once the mounting screw is tight as humidity will change the stock tobarel contact. Right? Is there anything I need to know before taking a sand paper- wrapped dowel to the stock barrel inlet to open it up so thebarrel won'tcontact? Or is this a bad idea???
