h-BN (hexagonal boron nitride_

[ol'pole]

I've been using h-BN for years, both as a lube and as a bullet and barrel treatment. I mix some h-bn with my lube oil and grease (they take on a milky appearance) and I mix some with my clp to condition the barrels.
I shot some softer lead bullets thru my Security 6 .357, full power loads and barely any leading. This stuff is more slippery than Teflon
I bought the 1/2micron size from what I've read that 1/2micron will fill the porosity of the metal and make for a smoother bore.
It can be found on AMZ and eb, I bought a small container .7 oz about 8 years ago and still have about 1/2 left a little goes a long way.
There is a video on amz and eb, under hexagonal boron nitrite distributers (bullet coating .com)
I don't go thru all the steps he does but what I do works for me, I'm not shooting long range (1 mile) like him.
