I read that too by Dan Lilja. But I know from experience that if you leave CR10 in the barrel for more than 10 min, you will get rust out of the barrel. That doesn' t sit well with me.

Who knows, I am beginning to think all these years worrying about this and that is just a bunch of voodoo magic. Man, this shooting hobby will drive ya nuts. All I know is I don' t want to pay to have rebarrel again. It ain' t cheap.
