Had some success with Moly back when I was prairie dog shooting but since have stopped using it after reading a lot of negative reports, but what are the pros and cons of Boron Nitride?
David Tubb sells a kit to coat your own bullets and here's his video explaining the benefits. As with moly, you will lose some velocity compared to bare bullets, due to the lower friction/pressure. You can add back a few tenths of a grain of powder to get back the velocity loss.
I fooled around with moly when it first appeared, but after Dyna Bore Coat appeared it used it in my prairie dog rifles because it only had to be applied ONCE to the bore, rather than to every bullet.
Haven't tried boron nitride for the same reason. Maybe its benefits make it worth the trouble.
I have a 6x47 Lapua,with a Kreiger barrel. All I,ve ever shot in it are David Tubbs 115 grn. D-Tacs,coated with Boron Nitride. I,ve never had a barrel clean up as fast as this one. I don't know if it's the barrel quality, or the coated bullets. I do know that most of the guys that shoot the D-Tacs are shooting the coated bullets.
Is the coating easy to clean out if you were going to shoot regular copper bullets or does it leave a backed on layer like Moly that takes a special cleaner, and some say you can never remove. One of the reasons for the question is that I have a 243 that likes the Federal Fusion 95gr coated bullets and I also like to use regular copper bullets in a lower weight for coyotes. I have read that Moly will leave a layer, then shooting copper bullets leaves copper on top of the Moly layer, and continually builds. Have read reports of people ruining barrels with Moly, and don't want to do the same thing using the Fusion ammo.

I'd say the basic premise is that one will do ALL of his bullets with the Boron Nitride, and forego untreated entirely. I had GREAT luck with Moly,...but with the attendant low "fouler / sighters",...
Learned fast that"LAMINATED" alternating layers of Moly and copper were just a flat PITA, and that a moly treated barrel needed moly and moly only for it's functional lifetime.
