after much research and deliberating, I've decided to try hbn coating/barrel treating. I want to have as much know how and information at my disposal as possible. So if any of you are using it I would much appreciate your advice and experiences, and even to learn from the mistakes of others in hopes I avoid them - ie what not to do, what didn't work.... I'm going to be using it in my .300 win mag savage long range hunter on 225 grain hornady eld match bullets, first powder tested will be imr 8133 as Hodgdon shows it pushing a 230 Berger over 2800 FPS, it's temp stable and I live in a place that routinely gets over 30 Celsius in the summer and -30 c in the winter, and it should keep things clean with that copper eraser. Hbn- what did it do for you, how did you make it work?
