I am looking for opinions about the moly coated bullets from some of you who are using them . Since 99% of my shooting and storage will be in a fairly humid and salt water environment, I am wondering if the moly left in the barrel will be an added problem. I have heard it will draw and hold moisture more readily?
Has anyone used the molys long enough that that problem would have shown itself? And if so, did simply keeping the bore well oiled while in storage take care of it, or was a thorough cleaning of the bore after each use required?

Since it is insoluable in water it follows that it is non-hygroscopic.

Well, I don't know, but there's been occasional reports in the benchrest circles of rusting in barrels that shot moly coated bullets since the NECO kits first hit the market. While there's more heat than light on this matter, I gather it only happens with barrels that are stored in humid conditions without any oiling after shooting, and then only rarely.

This thread touches on it a few times.

Moly has kind of fallen out of vogue, I know there are a few guys here that have used it and from what I remember they said it is messy and more trouble than it is worth. The bore needs to be "seasoned" with moly after cleaning and it is a pain to clean.

Tried the molly bullets...not for me. Have read reports of those who loved them and claimed all sorts of advantages. I never saw any, but am willing to belive that someone has.

Do like moly applied to some triggers...strikers...etc. A slick dry lube doesn't collect dust or freeze up in real cold weatehr.

Other than those two uses, have moved away from any use of moly.

If you dont mind being non-tradtional, a well molly coated black powder bore does seem to clean up faster (coated in the tradtional way, by patching...not by coated bullets)....the molly coating doesn't seem to last real long, but at least three or four shooting sessions.

Agree with rs - have tried it and went back to plain jacketed bullets. Marshall Stanton questions its use on cast bullets, also.

My .223 Rem Ruger M77mkII V/T is the only firearm that responded in a positive way to the moly treatment.

It does not do much to improve accuracy, but for those who shoot a lot at one sitting keeps them from havong to clean so often. My guns also do better with jacketed bullts. No molly. I know guys who swear by it. I have not heard about rusting a barrel out sooner though. I wonder if its not the molly trapping the moisture, but that you don't oil the barrel much since there is molly in it?? Just a thought.
