So I take it this is not an uncommon problem. Here's what I did. I took a two sided piece of tape with a piece of patch material stuck on one side and trimmed it to the size of the flat of the stock. I placed the tape with the patch material at the muzzle end of the lug notch in the stock. Thus raising the barrel and the bottom of the lug a fraction of an inch and tightening up the fit of the wedge pin. Please, tell me what you think. Maybe this will throw the barrel out of level and affect accuracy?
