Can I use Moly coated bullets to break-in my barrel?
Some bullet and barrel makers say that the best way to break in a barrel that is to be used with moly bullets is to break it in with moly coated bullets. Others say to use uncoated bullets to break the barrel in, then start using coated bullets. We hear from a tremendous amount of top-notch shooters and gunsmiths and they all have their own opinions on this subject (as you already know). In compiling this wealth of information, we have come to this conclusion: There is no BEST way. Some barrels seem to break-in very quickly with coated bullets. Some seem to take longer. We’ve had shooters tell us that if a barrel didn’t seem to want to really “come-in” with coated bullets, a few uncoated bullets down the barrel actually helped the initial break-in. Then they went back to the coated bullets with good results. Our recommendation is to load and tune the rifle with jacketed, uncoated bullets. Then try the moly coated ones. Back to top.
