Moly-coated bullets question

[Pat Riot]

I am curious. I shoot moly coated lead bullets in my handguns but I also shoot them in my Winchester 94 30-30. They are 160 grain FP bullets from Bear Creek Supply. I have never heard of these issues with moly. The BCS bullets are coated with moly and carnuba wax. Should I be cautious with this as well if I wish to shoot jacketed bullets?

Edited to fix the wax name…I hate auto communista!

Their literature says they use molybdenum-disulfide but it doesn’t mention carnival wax. If they work for you stick with it and just take normal precautions; run a dry patch after shooting and keep an eye on the rifling. If you see signs of frosting, do a thorough clean and see if the bore has any unusual signs of wear.

Moly just trades one kind of fouling for another, and it gets into your dies and tumbler media and all over the 6 PPC page in your manual and it won't ever, ever go away.

I gave up on it - with prejudice - decades ago. If I had any left I think I probably would try to trade them off or sell them, or maybe donate them to Russia as a way to interfere with the war effort.

Sorry, I wrote ”Carnuba wax”. Apparently auto correct decided I needed to look stupid or test my proof reading skills…

I was told BCS used carnuba wax with the moly. I do not know this for sure.

Carnauba wax. Its possible that’s how they seal the coating to prevent transfer, like others have complained about. The carnauba wax would keep everything cleaner.

Thanks for the comments. I'll use this feedback to go ahead and use them (they are Hornady) as-is. And this is good to know as I already have some.

JB bore paste can clean out Moly also.

Hoppes#9 would probably work

Ya less friction = more powder one other advantage with moly you can go more rounds between cleaning

How many rounds do you need to shoot before cleaning to justify this as a tangible advantage? I’m taking my rifles 300-400 rounds between cleanings, extending to 500-600 wouldn’t change my life. Maybe not even extending to 1000, in the scheme of things…

As far as moly-coated lead goes, "Back In The Day" Bull-X sold CSJ-branded (for Carter S. Jones, one of them old-time competitive shooting fellers moly-coated lead. They used a single lube process (unlike what @Pat Riot wrote about Bear Creek who seem to use a two-lube process) for competition bullets. I think Matt Dardas took up that market segment after Bull-X passed and I guess Bear Creek is taking it up since Matt retired. I have some of the old CSJ 240gr. .430" bullets and they do shoot cleaner than waxed, same as poly-coated, and I do not have to do anything special before shooting copper. I do clean with Shooter's Choice first then Hoppes, and finally clean/lube with Ballistol. Just nylon brushes and cotton patches. Takes around ten minutes to clean a gun from out of the holster to back in the safe. That includes admiration and appreciation time, though.

Always time well spent!
