HBN takes all that hassle away. Reduces ES and no where near as messy. Definitely not as slippery as moly but.

Kiwi Greg put me onto it ages ago. He has been using it longer and may have more light to shed on it than I.
I just know it is good stuff and I have never had a visable trace of coppering since using it in quality barrels.
Dont even get a patch come out coated in anything but carbon.

Yep any moisture anywhere + moly = corrosion

I don't know how much good HBN does, I have been using it for years, after hurting barrels with Moly.
I clean bugger all & once the rifle has settled down basically no copper fouling is evident even after 100-200+ rounds depending on calibre.
I don't really notice any carbon build up, although I don't have a bore scope yet, but don't know if I want one........
I have noticed that I have quite a few rifles now with silly single digit ES (more often that not), especially with mucking around with neck tension.
I haven't read or seen anything bad about HBN so I will keep coating all the pills for my own rifles, I'm careful not to use coated pills for customers rifles.
I haven't done enough testing yet to see how much difference it makes yet but will grab a nice consistent rifle & load to try with & without HBN.
