It was one of those things that I read one time, didn't think I had a use for, but now maybe I do but can't find the info. I do know they tumble ball bearings in the manufacturing process to make them more round, but that is about the limit of my knowledge on the subject. Prolly fixin' to do an experiment, will let you guys know how it turns out. Might not change a thing, but my mind is curious and wants to know.
