Moly bullets and poweder fouling

[AlanF]

Alan, you have used more Moly than any of us, do you think it reduced the hard carbon build up?

Rod,

I have been using moly throughout my F-Open career, and only bought it once. A 100gm container of it has done approx 23,000 6.5 and 7mm bullets and I still have about 20% of it left, so will be in the market for some more in about 2 years time!

Now you may think this is avoiding your question, but I'm not well qualified to answer it, having used bugger all bullets uncoated! But I will say I've never been aware of serious carbon build-up in any of my barrels. Recently there has been some talk of "ceramic" carbon fouling - again I don't believe its happened in my barrels. The roughness in the throat area I've always put down to erosion of the steel bore from heat and pressure. To smooth this out I use Iosso every 200 or so rounds initially, then more frequently as the barrel ages. If that is actually due to carbon build-up (and I don't claim to know definitely), then it sounds like moly doesn't prevent it.

I might be off track here but tungsten is used elsewhere in abrasives and drill tips.
Is that what is in the coating on your bullets?

Tungsten is used in drill tips, Tungsten Disulphide (WS2) is a lubricant.

Thanks for the feedback on the HBN guys! Rod glad to hear you had some good success with it in your .17! Geoff I might take you up on that offer down the track! I'm not in any hurry at all. . . just waiting for all the pieces to come along at the rite price at the moment.
