I've been occasionally impact-plating bullets with HCPL-grade hBN using #7 steel shot in a Lyman vibratory cleaner.
I was having some trouble with a new batch of bullets and after a bunch of debugging got some to come out with what felt like a reasonably lubricious coating. But unsure whether I have the kinks out of the process I test fired them in a 26" barrel against uncoated bullets. My assumption is that if they are properly coated they should print significantly lower muzzle velocities than uncoated bullets in the same load and barrel. The coatings I have right now have no effect on muzzle velocity. Am I correct in concluding that I have not properly coated them?
