I'm just wondering if any one that has one of these little pumpers has ever found a pellet that has any accuracy. I just mounted a JTS 4 X 30 it's a great little scope but the Crosman M4 so far has been nothing , but exercise pumping it up. I mean 15 shots , or 3 mags at 10 pumps each is 150 pumps. Any advice on a accurate pellet would be great thanks OV.
