You will be more accurate with a non-wood stock in most guns. Though not much, every time humidity or temp changes stock shifts/warps to some minor degree. God forbid you are a true hunter and you spend 8 hours in the rain and then carry your gun in a nice climate controlled house to dry out.

Yes yes yes I know 400 people will reply and tell me how they have a wood gun that shoots 1" groups at 800yards while snowing in 95 deg weather, but consistency is the name of the game and wood warps. With lots of work or luck wood can be as accurate as anything, but your average off-the-shelfer will not like weather changes or water. Yes millions of guns are wood and work perfectly for what is expected from them but you said you wanted accurate.

To the earlier thread about the BOSS system, nah! With recoil comp too loud. Too much junk on end of barrel, clunkie. And as an added bonus the last one I saw we cut the boss off and the barrel recrowned shot just about as good as it did with the BOSS.
