I just ordered enough hexagonal boron nitride to coat a couple years worth of bullets. I have been thinking of trying it for a bit and I finally made the cheap purchase.
I'm most interested in what's going to happen with my BHW barrel, the polygonal twist already keeps pressures low and HBN is going to drop it a bit more.
I've done a bit of looking around to find others results with HBN and it seems to make a noticable difference with pressure, allowing more powder and ultimately more speed, not in small amounts ether. Similar to my poly twist results.
So who knows what's going to happen? I havent seen anyone shooting poly twist barrels with a lubed bore and bullets and my poly twist 223 loads are already off the charts. What kind of speed can be had? Any accuracy..? I've seen this gun hold 12+moa.
Ive got H322, Benchmark, H335, Varget, and CFE223 on hand, a bunch of Hornady 50gr SP and some TSXs. I will be picking up another box of 65 SGK to load up also.
I also will be playing around with my 260AI and 140gr VLDs with it's big 30" barrel, some online reports were showing over 150fps potential gain from HBN in 6.5 Creed 24" barrel. If I can add 100-150fps or more to a 140 VLD that will be nothing to sneeze at.
Has anyone else around here played with bullet coatings?
