Any advise you can give will be greatly appreciated

I stay with Moly coating as it has proved itself and there is a mountain of scientific evidence on it's properties and what it does and it's limitations . NASA even did experiments with Moly in outer space .
Soak the bullets in a 1/2 liter of warm water ( warm only ) containing 1/2 cup of CLR for 5 minutes . Then wash off in very hot water and let them dry .
Then wash the bullets in white spirit ( Shelllite) , let them dry . Then coat . Don't handle the bullets at any point in the process use clean forceps or very large tweezers to handle the bullets . If they don't coat then the alloy is contaminated in some way .

I doubt very much that the outer Edge bullets are actually MoS2 moly and when I use my process none of the moly comes off on your hands at all . Most people just don't know how to do it properly .
As a lube substitute powder coating probably works but that's about it . Proper Moly coating works as a lube , a friction modifier , a bore protector during firing , gives more consistent bullet release and it stops neck welding in long term stored rounds . However it must be used in a certain way . Like people who clean after every 20 shots or so will get little benefit as they are stopping the moly doing it's job . I conferred with NASA and National Laboratory Los Alamos NM USA to develop my understanding and process . I am not trying to convert anyone I was just saying I looked at powder coating and I'm not interested .
JohnV wrote:Cast bullets and jacketed bullets Moly works on both . However on a cast bullet you have to get a good deep coating for it to equal the lubrication ability of wax based lubes and that is the area that the thicker coat of powder coating would work ok .
The problem is it's too easy to get a black Moly colour on the bullet with a quick 5 minute tumble and then people think they have done a good job and it's not good . Even some experienced target shooters I have spoken to make this mistake and their coating is piss weak and basically useless and they also clean too often and Moly never gets to build any Lamellar structure in the bore , totally pointless .. This gives the process a bad name . When I took my 223 away I never cleaned for the whole shooting trip and have fired as many as 250 moly rounds with no cleaning and the accuracy does not drop off . Can PC do that ?
I clean it thoroughly when I get home and lube the bore as Moly will not stop corrosion because it's Lamellar structure can't exclude Oxygen and moisture from the steel like oil or grease can.
