Home Forums Hunting & Shooting Ask The Gunwriters Question for MD/JB: Moly coated bullets - Salvation or Damnation?

JB, a lot of emotion on another forum about effect of moly coated bullets on barrels. I've heard and read so many different opinions on this that I'm unsure of what reliable data actually shows. Can you tell us whether molybdenum disulfide becomes irreversibly bonded to barrel steel? Is it removable with such agents as JB Bore Paste or other relatively common cleaning methods? I don't use moly coated bullets but have some of the old moly-coated FS 338s and wondered whether shooting them would alter my barrels irreversibly. Your knowledge would be appreciated. Thanks
