Re: Relaoding 6.8 SPC
For J.E. Custom and Catskinner, the powder I used was H322 for both loads. The Boran Nitride coating, I used to send all my bullets to Superior Shooting Systems and have them coat them and send them back but now they have a kit you use in your tumbler and do it yourself. They used to be be so backlogged I would wait for a month to get them back, and the shop runs 7-days a week, orders were Monday -Friday. But now I can coat whatever I want when ever I want to in 2-hours. It cuts down on friction, and barrel heat and extends barrel life. -----------But since there is less friction there is less chamber pressure so if you have a "Naked Bullet Load" already worked up and you use coated bullets your velocity will drop a little, but that's ok because you dropped the chamber pressure more than you dropped the velocity. To get back to your original velocity you'll have to add a small amount of extra powder. But you can very easily end up with a higher velocity and less chamber pressure. You'll notice the barrel heat reduction more on the hot rod magnum calibers or sustained fire on a regular caliber. You can call Superior at 806-323-9488 or go to Superior Shooting Systems.com. My alarm is going off in 5-hours so I need to go, but I'll send ya'll some data from 6.8 forums. I looked at our chrony sheet and that 100 gr load at 2,900 and a factory 100 gr Federal load in a .243 Winchester with a longer barrel was 2,720 fps so it has more punch than a .243. You'll loose a little with the 16" barrel probably 50fps but it will still be plenty lethal.
