6" groups at 100 yards is a major drop in accuracy. I would remove the barreled action, and clean the action and bedding surfaces, and properly clean the barrel with a one piece rod, bore guide , cotton patches.and a good copper solvent.If that doesn't restore the accuracy, I would inspect the muzzle for damage, and then retighten the scope mounts. If that still doesn't do it, try another scope.
