barrel seems dead. l took apart the barrel and action from the stock to cleen it and put it back for the first time this week. could that do this aswell ? never took a stock off before. 3 shot groops dont take notice of other holes around the groops. distance 50 meters.
well the simplest answer l can give is.. after takeing it apart but leveing the scope on, the zero went from dead on at 100 yards to 5 inch high at 100 yards. its a heym sr 30 so the barrel doesnt screw on anywhare its a complate 1 piece steal.. bolt - barrel- and triger.
If you cleaned the bore to white metal, you may need to re season the bore by shooting it. can someone explane this pls ?
