resizing 6.5 grendel to .243 LBC

I stopped at ejector flow. according to QL that was about 58-59000 PSI. I could make them go faster 3000+ , but backed off .5 gns to save brass barrel. According to your load QL puts you about 59000psi and 2719 fps. Granted that was using the 6mm AR. To get 2800+ I had to add a grain(29 gns 8208) and the resulting chamber pressure increased to 66000psi.
