dry lubing bullets and barrel bores with hexagonal boron nitride powder

[Dusty1]

Does anybody have experience with this dry lubricant. Ive been doing some research and seems to be superior to both moly and Tungsten Disulfide (WS2). A friend lubes his bullets and bore and claims that after 100 shots he has no bullet fouling at all. He also claims that his accuracy has improved from 1.5" to .75".
