Welcome. There is a lot of good information on this site. You will definitely want to check out bullet performance info. It is spread out a bit, but a large amount is in the "Hunting with the 6.8 mm" as well as the "6.8 SPC Ammunition and Reloading" forums.
Here is an excellent thread: 6.8 SPC Bullet Performance
Thank you for the welcome,
I have had a chance to browse around here a little bit and I see a lot of quality info,
I actually do have a 6.8,
years ago I had a chance to pick up an LMT mrp cqb when they were first introduced,
I grabbed a 300 blackout, 223 and a 6.8spc barrel to go with it, unfortunately 6.8 was nearly unobtanium at the time so unfortunately it’s been hiding in the back of my safe all these years, time to play
