I have a model 70 Featherweight 22-250 circa mid-80's and it shoots erratic patterns even when cooled between shots. I suspected uneven forend pressure and found that it is virtually free floated on the right side and is binding on the left side of the barrel channel nearly the full length. Should I relive wood on left side or 2] glass bed the whole thing?
How "erratic" are we talking here? I would start by free-floating the barrel because you are going to want to do that no matter what. Also examine the crown with a strong magnifying glass and be sure there are no dings or anomalies on it. Then pillar and bed the recoil lug and action, with pillars. There is a person on eBay selling great pillars for Model 70's, if you are going to do it yourself.
And yes, it is a mistake to tighten that middle screw much at all. Just snug it enough that it doesn't rattle loose.
