There are folks applying a HBN mixture in 99% alcohol carrier solution to squeaky clean bores, that claim this impregnates the bore with HBN with the first bullet fired down the bore. Then you don't have to wait for the HBN coating on the bullets to be transferred from the bullets to the bore. This is strictly armchair knowledge I collected while researching the internet. I do plan on treating my clean bore with this HBN/alcohol solution, based on what I've read about it.
phorwath is your expert here. He has read every post on hBn coating. Really knows other peoples stuff.
By his own admission he's coated 1000 bullets but hasn't shot them.
IIWM: I'd check with someone who actually shoots them, checks his bore with a scope and watches his throat erosion/movement with documented offsets from the lands and changes every 100 or so rounds.
Perhaps by PM instead of here.
