I use both Remington and SSA brass. Both seem to be quality brass. Point of impact is a little different using the same load in each but the grouping stays pretty consistent. Since I load the .223 in bulk I have alot more small rifle primers so as I wear out the Reminton brass I'll probably transition to SSA brass only depending on availablity. I wish I hadn't seen pictures of that rifle. Now I want one. That has to be a sweet shooting gun in 6.8. Not near as much recoil as a .308.
