Has anyone watched and tried the 10/22 tuning method on You Tube posted by James? It's pretty simple and he says his stock rifle is as, if not more accurate than a match barreled rifle. If you haven't seen it, the process consists of removing the barrel and action from the stock. Giving the gun a complete and thorough cleaning and then giving the barrel 2-3 wraps of electrical tape right where the barrel band mounts to the gun. Re assembly by tightening the stock to gun first and then re installing and tightening the barrel band.
