Kroil penetrating oil is supposed to do a pretty good job taking out moly, should you choose to do so. From what I understand, you want a coat of moly to already be in the bore when you start shooting, to avoid changes in point of impact while the moly coats the bore. After following several points of view on the pros and cons of moly, I decided that it all sounded like more trouble than it was worth, for me personally (especially in a lever gun, there just isn't much point to it). I haven't heard too many middle of the road opinions on moly, but if your rifle likes 'em, that's really all that matters. Obviously, it would be better to get a reply from someone with more experience with moly coated bullets, but what the heck, I'll put in my $.02. If I was going to shoot moly coated bullets in a high velocity rifle, I would clean the barrel down to bare steel, swab it with one of the moly bore-prep products on the market to get it started, and then I'd just use a powder solvent to clean it. If that method led to good accuracy over time, I'd stick with it, and only clean down to bare steel once in a great while, or if accuracy began to fall off. If groups started going south right away, I'd try a different experiment. Still, I've heard of bad things happening to barrels underneath that coat of moly, so I'll probably never get around to trying it. It's nice to make good groups at the bench, but I'm happy shooting minute-of-venison from field positions out to the effective range of the cartridge I'm using. Let us know how things go with your experiments, maybe you'll come up with a reason for me to try something new, and that's always fun.
