Thread: Moly for barrel?

What about using hBN to dress both bullets and barrel , I bought some and never used it . Using hBN , allegedly improved extreme spread and extra velocity could be achieved . Unfortunately , the accuracy nodes remained the same but required more powder to achieve them . Waffle aside , perhaps its lubricant properties would be of benefit when using monolithic bullets . It's also claimed to help prevent copper fouling and has a much higher resistance to temperature than moly .
Perhaps, someone has experience of using it on here .
