I have a Crosman Redtail .22 break barrel pellet rifle. My shots are of varying accuracy (some holes are touching and others inches apart) and I think I might have found the culprit.There is about a millimeter of side to side play in the barrel when it is cocked and closed up. Does anyone know how oI could fix this? It would also be helpful if anyone could point out other reasons for my lack of accuracy. Dove season starts tomorrow and I would like this problem fixed soon.
