hBN (Hexagonal Boron Nitride) vs fouling

It’s a huge amount. The powder is light and fluffy and just the amount you can pick up with the tip of a toothpick can treat a tin of pellets.

I have not. I’ve only put a tincture in a small ziploc with maybe 100 pellets and gently shook them until there was a very fine amount on all of them. If they look at all white I roll them on a towel to roll off excess.
What would the plan be for the wax? I have Renaissance Wax.

I've mentioned this tip a few times but if you take a "copper" charbroil pot scrubber (don't buy the stainless or bronze because it will damage your barrel) then cut some off, and wrap it around a brush once or twice so it's only a snug fit in the bore, it will scrape all the lead out of the barrel quickly, and it doesn't take much effort. Only go from breach to muzzle.
Then clean as you would otherwise.
I learned this from a old friend for pistol shooting with lead bullets and it's way faster than using the chemicals or current products. Could probably follow up with chemicals but I didn't feel the need for my application back then.
BTW I'd be wary of using anything that attracts moisture inside a barrel, especially in humid areas.
Example - I won a new soft case in a raffle once, and left my FX Royale in it for a few weeks, and the steel got pretty much ruined from excessive rust because the foam inside the case, as I found out from researching about it, "attracts moisture". I live in Arizona BTW and in a arid climate.
It caught me off guard because I've left guns in my other cases and never had this problem before!

I was thinking of a mix with the renaissance wax..i do not think i will add too much. Mix it together and apply to bore .

This link provides several options, do you mind providing a link to the specific lube? I think I know which one, but want to be sure.Here is the website page for the Micro lubrol product

Hope this helps

This works real well. I polished my barrels and liners with 5000gr and 7000gr diamond polish. They do not foul up shooting hybrids near as offensive as before. I told a friend about a kit for the diamond polish. He used it then told me his guns that where not accurate are very accurate now. Seems like each time I use it my liners get more accurate,I've not destroyed a liner or barrel to where I've seen accuracy decrease. People have sold me liners claiming they didn't shoot good at a discount,after polishing them ,less than 5 minutes they become accurate or where accurate before I recieved them,now first thing I do when getting a new barrel or liner is use the diamond grit polish. Far as fouling,when shooting lubed pellets and my accuracy has decreased,I shoot a few jsb non lubed pellets thru my guns. Accuracy comes right back. The non lubed pellets clean the bore cause it's so slick. That's how I do it,seems to work for me very well.good luck,I’ve been shooting a lot of slugs lately and I’ve noticed that they foul up the barrel quite a bit faster than pellets.
My quest in finding a solution has led me through barrel polishing, projectile lubing, etc.
Recently I was introduced to a barrel/projectile coating product called hBN (Hexagonal Boron Nitride). Supposedly it has some of the lowest friction on the planet and it claims to fill in the microscopic imperfections.
View attachment 509892
I took the advice of thoroughly cleaning a barrel to remove all build up/fouling and any petroleum products. Then I mixed the hBN with 99% alcohol, mopped the barrel, let it sit for 20 minutes, then pulled a few dry patches through.
Holythis is some crazy slick stuff!!!
The powder claims to be 0.5 microns, 900° heat resistance, and have super high pressure resistance. There are quite a few long-range powder burners who swear by this stuff, so why not use it on Airguns?
Some say it minimizes their extreme spread, while most say it significantly reduces build up and facilitates a quick easy cleaning.
I’ll probably end up cleaning/coating my projectiles in the same solution then polish (wipe them off) with a microfiber towel. I’ll check back in a few days to share my findings. But if anyone has used this stuff please chime in.
*update - I’m being told that’s in order for the hBN to crystallize and embed properly we should shoot a few (fire-lap) hBN coated projectiles through it after the powder has dried in the bore.

Ebay has a kit. Anything under 5000,it only takes a few stokes. I take my rifling down all the way near about. Start with 1000gr,3to 4 stokes,then 2000gr 6 stokes,and so on. Anything below 5000 takes metal away,becareful. I push a pellet thru with a rod,look at results,feel how easily it pushes,don't take alot off the muzzle end,if you barrels choked. When done I clean,then I don't put any more solvents in my liners or barrels after that. Been shooting a 600mm 30 caliber liner for over a year,doing it this way,it still will shoot rugged .5 inch 5 shot groups at 100 yards.

A mop,it takes very little. I don't use alot of the stuff. Still got half a tube of 5000gr and done polished over dozen liners or more. A match shooter told me this to make my liners more accurate, I don't have an unaccurate fx liner,and I got over 20 of them . That's why I don't know why people take negative about them, I've never got one that don't shoot good. Two days ago,I got a 700mm 1in22 twist 30 caliber. It looked bad inside it. I hot it with 5000gr for about ten minutes till it was mirror. It shoots 50 grain aea really good tensioned on my m3. This good at 100yards,over and over. I shoot groups like this in the wind. It's how I practice.

I use the dry slide EP liquid grease, A little story about this stuff, I lubed my brothers 2000 year brand new KLR 650 clutch cable, After 23 years and 30,000 miles I pulled the cable out to relube it and that crap was all over my hands , After 23 years and 30,ooo miles that crap was all over my hands , Takes hot water dawn soap and a hard brush to get it off your hands, I use it in all my barrels after break in,, Oh its flameable so you have to let it dry for 12 hours, or I do.
If this new stuff not as messy I may look into it,

I wouldn't recommend this. The objective is for the hBN to bond to the clean metal barrel and fill the imperfections. A wax would likely hinder its ability to bond properly.

I think you're right using 90% or higher alcohol is probably the best medium for applying this stuff and for proper application, a spotless clean barrel. Anything else would probably not last anywhere near as long.
In my application with the mix with lemon pledge it kept the barrel cleaner than not doing anything. I plan to do the deep clean and reapply later this weekend with the alcohol.

I have some more interesting results to share.
Today I did a bunch of slug shooting using my RAW HM1000x (with hBN coated barrel).
It looks like it took about 200 rounds to knock off all the high spots / excess hBN. During this period I was seeing a decrease in velocities & accuracy. Especially with heavier slugs which I believe have more contact/surface area.
Every 54 shots (3 full Stud magazines) I pulled 2 dry patches through using a Patchworm. Initially the patches were fairly dirty (sorry no pic).
Now after 200 shots the velocities have returned to normal, the SD is extremely small, and the accuracy is just as good (if not better) than before.
The most interesting part is how the hBN appears to be repelling (not allowing the build up) of the lead on the imperfections.
This is what a single dry patch pull through (using a Patchworm) looks like after 54 shots with H&N slugs
This is what a single dry patch pull through (using a Patchworm) looks like after 54 shots with ZAN slugs
That’s pretty freaking cool if you ask me!
*Note that H&N using a petroleum based lubricant to prevent corrosion, while ZAN does not.

Hexagonal Boron Nitride (hBN) Powder | Hex Boron Nitride
Hexagonal Boron Nitride Powder- One of most reliable lubricant for high temperatures. Hexagonal Boron Nitride can provide lubricity at temperatures upto 1400 deg C.
lowerfriction.com The most efficient way to apply hBN to the land surface pores is via high pressure. The best method of achieving this high pressure is during the swaging of the pellet as it is being shot.
Apply hBN directly to each pellet DRY. Use these pellets in a clean dry bore. After about 200 pellets the bore will be good to go.
Continue to lighty dust your pellets in order to maintain the hBN density in the land surface pores.
