I wouldn't. The benefits do not come close to outweighing the drawbacks, imo. My understanding is that once you shoot moly coated bullets, you pretty much have to always shoot them, it's almost impossible to get the moly out of the bore once it's in there. Then there's the fact the molybdenum disulfide is hygroscopic (it attracts and traps moisture from the air), that can lead to barrel corrosion and pitting. My brother mentioned that he was thinking about trying moly coated bullets in his deer rifle when I was up there this year, and wanted to know what I thought about it. I talked him out of it.
