Picked up over 500 55gr fmj that are moly coated, have heard horror stories about barrel pitting etc. Should I try to remove the moly in a tumbler, trade 'em off or shoot 'em up and go on. Oh this is in a 10" Hornet barrel for field and hunter pistol. What say you?

I originally heard that moly bullets were supposed to be more accurate and "season" barrels. I later heard that such claims didn't prove to be true and the moly thing sorta died out. I still see them for sale so some people must like them. I never heard any stories of pitting barrels but I admit I never paid much attention to moly bullets. If you can find an accurate load, you have a lot of shooting ahead to burn through 500 bullets. Unless you find someone who wants to buy them or trade for regular bullets, then you might as well shoot them. Again, if you can find proof of barrel pitting then I wouldn't use them either. Sorry I couldn't be of more help.

Moly does not Pit the barrel but has it is annoying. It actually protects your bore as it is actually a lubricant. BUT after the bore is coated with Moly, it will show up every imperfection in the bore

The most annoying problem is that the bore must be coated with moly, or accuracy can drop off. usually you have to do the following:

1. The Bore must be Clean of ALL copper, lead and powder fouling.
2. after it is cleaned, the bore needs to be coated with Moly. Most people will run a patch with moly on it to Pre-coat the barrel or just shoot some moly bullets through it. Note, accuracy will not be good till the barrel is coated.

here is a little explanation what to do with moly bullets:
