[QUOTE="Mikecr, post: 2502482, member: 1521"] I know nothing about HBN, but it's important to understand that moly does not lower MV due to friction change. Instead, with moly, there is a cooling of the charge as moly vaporizes. This does reduce land erosion, but unless moly is managed perfectly, accurate barrel life itself goes down. For sure HBN would not have the exact same affect. WS2 has a far lower friction coeff than moly, and it does not affect MV at all. [/QUOTE]
