You might look at the LWRC International website. They are selling once fired Federal 6.8 brass for $280 per 1000.
The Federal brass is really nice. Strong consistent case web and excellent capacity. I have looked at cross sections of SSA, Federal, Hornady and Remington. The Federal had the best combination of case capacity and a strong, rounded and uniform case webbing (my term - the inside corners near the base) of all the brass we looked at. I have yet to see a case head separation w/ their brass.
