We were doing testing on BN coated bullets and Barrels back in 1995. Even went as far as applying for a patent.Which we found was not easy do to the fact People have been swabbing barrels for decades. Also contacted Olin Corp. at the time would not talk to us unless we had a patent. We’ve personally been using this since 1995.

Bullet coating will be debated regardless of the material used.
I use Moly and HBN separately in different rifles. Both provide the results that give me confidence that coatings do something. If nothing else they allow me to develop loads that perform as I want them to. Predictable velocities and terminal performance are benifits of coating in my experience.
Barrels begin the process of wearing out from the first shot. I cannot say with any degree of surety that my barrels will last longer than any other barrel.
I have used moly since the 90s and have yet to see corrosion caused by the reaction of moly and the atmosphere.

I have used HBN since I first heard the buzz somewhere between Robinett and Tubb and have not experienced any detrimental effects that could be linked directly to HBN.

In a nutshell: Use it or don’t .

David Tubb did NOT pioneer the use of hBN coated bullets. RG Robinett, and I, along with others, were using it in 2005.

Still no word if it actually helps with the barrel life

HBN seems to be made using ammonia, possably boric acid, and ether sulfuric acid or hydrochloric acid. Any chance if the product decomp’s it will bond with whatever is in the air and recreate these or other unhealthy compounds for your barrel?

From what I have found, the spray is processed with a 15 micron filter. The spray will have particles as large as 15 micron, but no word on the size of the smallest particles.

have used it for at least 2 years. seems like less cleaning required but find cleaning less anyway. believe just thru only thinking about the problem is that; 1) the plasma/heat produced by the powder ignition eliminates the boron or moly coating in the barrel (not the bullet) and 2)the only fix to the problem of barrel life can only be addressed by the use of a ceramic sleve.

I wonder about carbon caused or left behind by the bullet coatings themselves. I’ve used WS2 for so long, that I have no comparison to consider..

I have often wondered if there will be health issues down the road with all 3 coatings from absorbtion through the skin and inhalation during the application process and again at the firing line. Mainly, black lung and silicosis or asbestosis type things. . .only time will tell. . .I guess you guys are the parakeets in the mine for the shooting world.

I have, and still do use hBN on bullets, and I still have a strong black ring, and no increase in accuracy or time between cleaning. I don’t know why I use it honestly.
