    Yup, HBN. Moly rooted a couple black barrels I had. As Tussock pointed out, mix it with moisture and you get a corrosion factory. They both still shot but looked like an umpa lumpa mine site.

    HBN is not as slippery as moly but it can never cause any bore problems. Cleaning is a breeze as well, I have yet to have a blue patch when using a copper solvent.

    Its not as slippery for want of a better word. I dont lose much at all as I use less powder to get the same speeds as moly.
