1 oz Hexagonal Boron Nitride hBN Powder Ultra FINE 0.5 µ Micron

This is an amazing product in many ways to reduce friction when powdercoating projectiles and building heavy use and abuse parts.As a must...Do some homework on what the product is capable of. It's worth the time.ie. After treating leaded steel. I found it almost impossible to do any more machining on it. The club resisted the sharpest of carbide cutter on surface. Eventually able to break through surface layer.I will leave one with this.Treated inside of a 12ga bore = 200 fps average in velocity. Cleaning was a cinch.One stroke done.

HBN Powder goes on easy, seems to work as advertised cleaner than MOLY.

Took a bit to arrive, but it did and it is what it says it is. Can be used for many applications, so use it for what you bought it for. I bought it to lube gun parts and bullets.

I've mixed it with a light gun oil and some light bicycle grease and I used it for many things. Seems to work well but I haven't made any scientific comparisons with it. So nothing dramatic with it so far.

Best dry lubrication product I’ve ever used. Highly recommend it!

I mix this with my firearms lubricant and to tumble my bullets and it works well. This thing is pretty big, it's probably enough to last me a lifetime.The packaging could be better though, as soon as you twist off the cap, the hBN is right there, no plastic seal.

Shipping time was good. Powder seems to be as fine as advertised. I purchased this item for a trial that I have planned but haven't had time to do it yet. I'll give an updated rating when I've had time to try it out. I have high hopes for it however.

I use a women's powder brush to dust the necks and resize brass. No cleaning of the inside of the necks.
