Downunder many of the lead bullet manufacturers are coating their bullets with a dry lubricant coating instead of traditional Alox or similar lubricant in the grooves. The colour varies, black, gold, blue are just some of the colours seen. These are all a solid coating covering the entire bullet, non sticky and no smell and they work extremely well in reducing/eliminating leading and smoke.

Anyone have any idea what these coatings are as I would like to try to replicate them for my own cast bullets.

would bet either moly or boron nitride.
moly is usually black and boron nitride is usually blue the gold may be titanium nitride.

I am familiar with various moly coatings and these black ones don't look the same. They are a shiny solid plastic looking film (as are blue and green ones). They look like some sort of dip process. Nothing rubs off onto fingers etc. The gold ones are dull and the bullets are rounded suggesting a tumbling type process. While you may be right about the lubricant it is the carrier that is different. Any ideas?

Check Westcastings.com to get an idea of just one of the manufacturers doing this. And yes it works. No problem using these bullets in a Glock.

? Anyone

iirc winchester done some loads with a nylon type of coating also called nyclad.
they discontinued it as i recall because they were "cop killers" or some other stupid thing.

G'Day Oussie,

I'm another Australian that's been shooting these coated bullets (from Hawkesbury River, Westcasting and Top Score), for years now.

I was initially told that these Coatings were a Teflon Based substance? Apparently, it starts out as a liquid and is applied in a cement mixer Type arrangement, similar to the way Almonds are Chocolate Coated.

Can't help with any more info than that but It Is the best thing since Sliced Bread as it sticks to the lead bullet at velocities approaching 2000 FPS!!!

Sorry Ossie but that's the best I can do for you

Not sure if they have been discontinued totally but they did have to change the formula because, at first, the bullets did not show the rifling of the gun that had shot them and would provide no forensic evidence in a murder case. Their original use was to allow indoor ranges that no longer could pass EPA requirements for lead dust to stay in operation.

I've been told that sellier & bellot uses a polymer coaqting on their 38 special lead round nosed bullet. Been trying to check the info on the boxes at local gun shows. Have not seen any such info on the boxes I have seen, but the s&b website does make mention of such a coating. If anyone else comes across this information as gospel mayself and a lot of other 38spl shooters would be glad to hear of it. Thanks, Frank

If you are talking about pistol bullets the performance requirements are not severe. The lube makers can add color tint to make you think they have something different when it is nothing but the same old lube. It is called marketing.

If you are talking about polymers, Teflon is available in paint or liquid forms. These coatings are commonly used in the semiconductor industry to resist highly corrosive environments. There are no reasons why, other than cost, they could not be used as a bullet lube coating.
