[QUOTE="Dirtrax, post: 2576701, member: 78945"] Larger bores realize a larger gain in velocity. As I understand it the material removed from the throat creates an improved heat sink. This extends throat life on some, but should not increase throat erosion on any cartridge. Fire cracking on my 7mm Practical has been minimal despite a 45 +/- fps gain. I also coat bullet and bore in hBN but had done so prior to Defensive Edge performing the work so it’s apples and apples. This bbl is about done so Shawn will be getting a call soon! [/QUOTE]
