[QUOTE="Calvin45, post: 1643697, member: 109862"] Thanks a bunch for sharing your experience, it’s what I’m after here! That’s fascinating, the “basically white bullets” thing...can’t argue with results. I would have been afraid to try that, very content with you having gone first. I have follow up questions: 1. Any issues with excessive force needed to seat bullets coated this heavily? Neck tension problems? I would have thought a layer that thick would increase projectile diameter enough to affect that. 2. How has hbn affected your velocity? Everyone has a different opinion and report about this, I want to hear yours. Generally what seems to be reported is that the reduced friction lowers pressure and with it velocity, but that the lower friction, particularly regarding the initial pressure spike when the bullet meets the rifling, allows for a significant enough increase in charge weight compared to naked bullets to allow higher velocities at equal pressure. Is that your experience? 3. If there’s so much hbn on your bullets that there’s a “puff” when they leave the barrel, do you have any concerns about breathing that stuff in? 4. I’m intrigued by your username. Do you indeed have a 6.5 wsm? How close does it get to .26 nosler/6.5-300 wby performance? [/QUOTE]
