So I've got a stainless syn 10/22 that just doesn't seem to be shooting well. It's got the newer style weaver/tip off rail. About 5+ years old, doesn't have a problem functioning with multiple brands of ammo. It's seen several thousand rounds. It's had 2 different scopes mounted on it and both are showing similar problems. Shooting Rem T-Bolts for the most part, with some Win X-pert. The rail screws are tight and thread locked, the scope and rings are solid, but I'm getting some odd behavior on target. I took a scope that was on a different gun, but had to crank it way right (you can see from the pictures) When I have the barrel band off, it's shooting like this: (POA was the center circle, POI was the upper left circle) Shooting high and left. The center "group" was still in the process of moving the scope to POA and POI to the same spot. Note the vertical is better. I installed the barrel band again and shot at the right circle. POA can be seen in this image. If you can call this a group: Ammo and gun were the same temperature, breeze was calm/none. Distance was about 30 yds. Shooting done from a supported position. The original thought was that the holes in the receiver are drilled off-center. Checking the holes with a caliper, I'd say they are in spec. I think we'll swap stocks next and try a different barrel band (with/without) and see if that can narrow it down any. What you do think?
