Not as strong as I used to be, but it seems like one has to have super human strength and a grip like a Pitbull's jaw to open the pellet tins from Crosman. Lots of advice on line, but the easiest and the one that always works for me requires only a butter knife. Just rap on 4 opposing sides of the can with the base of the knife and it is much easier to unscrew. May seem obvious to some. I had to look it up.
