Thanks for the input on that, Tom. The rifle is oldish (1976) but has probably not had more than a couple hundred shots through it. I put 50 or so through it a couple weeks ago trying to get it sorted out and they pretty much doubled the wear showing on the feed ramp and magazine follower.
My best results with it were two shots touching and a third about 4" high. I think the first shot was always the high one. I tightened the action screws and it changed to more of all three shots in a vertical line. Unfortunately the wind came up at that point and all results became pretty unreliable.
The barrel channel in the stock is odd. It is really set up for a pressure-pad at the fore-end, but the channel doesn't match the barrel contour well, so it is more like a V, with the barrel only touching at the sides. My first thought was to free-float it, but it is a fairly thin contour barrel, so maybe I'll do the pressure pad and see what happens. This rifle is an indulgence because I have an identical one in 30/06. I want the 22/250 to shoot well, but it is more about having a matched set than a tack driver.
