My HBN experience and process

Probably a dumb question but I'm assuming you have to coat the barrel every time you clean?
No, it's already there and the bullets impregnate the HBN more as they're fired. Residue and fouling, as well as throat erosion are reduced considerably. In my 338-416 Improved wildcat, I still found powders like RE33 and RE50 to be extremely dirty with powder soot, but the bore was still clean, just dull, but cleaned easy enough. Most powders used the barrel still looked shiny after firing 30-50 rounds…

Cheers.
