Has anyone had any experience with bullets coated with boron nitride? I've heard mixed reviews about moly coating, but while I was researching the subject I came across this article:
GUIDE to Bullet Coating
It says that moly and tungsten disulfide can both combine with moisture, forming harmful chemicals which can erode barrels, where as boron nitride doesn't. Also apparently David Tubbs is backing boron nitride, saying it is better than moly or tungsten disulfide.
Also I have heard differing reports about whether bullet coating increase or decrease velocity... Common sense tells me that with reduced friction you should expect higher velocities but maybe not?
Any info would be much appreciated!
