[QUOTE="lynxpilot, post: 1071946, member: 23349"] I'm currently in the midst of a HBN (hexagonal boron nitride) experiment. I didn't even get to the schweet load using untreated bullets and bore before I started coating, so I'll likely never get to the point of being able to say it's better than not coating, or better than WS2. My preliminary results after coating a whole bunch of projectiles and then coating a spotlessly cleaned barrel show that there is virtually no copper fouling after shooting a few rounds. And the rounds were Barnes all-copper which purportedly is a softer alloy than the jacketing on most bullets, therefore subject to fouling. I'm using HBN exclusively because of the articles I read. Apparently the melting/burning point is significantly higher than WS2 and Moly. It's supposed to be slightly more slippery than Moly and a little bit less than WS2 (if I recall correctly). It's white in color and is supposed to be non-toxic. Seems like it's frequently used to extend barrel life. It's also supposed to help the cold bore shot reflect more of what the subsequent group is going to shoot and that's the only reason I'm using it. I'll check for copper for a few sessions, and if it isn't showing up, I'll probably just run a dry patch after each session and re-coat the barrel after a few hundred rounds. That's just my experiment though, and it has no science or expertise behind it. [/QUOTE]
