If they only sell those calibers, do they also rent out the guns? I have never been to a range that rents gun at all, but I've heard many do. I suppose from a business standpoint, they see those calibers as very expensive to shoot, and not many people own guns in those calibers. Sooo... If they can get a few people a week to drop $25 on ammo and a another $$$? on a gun rental just so they can say they have shot one, or have the experience of shooting one, it makes sense.
