Depending on the brass you're using (if case volume is around 56.0 grs of H2O) and if you're going to load them to the standard 2.800 COAL, you might look at something around 41.0 grs. and use CCI-200 (assuming you're using LRP brass).Anyone got a good recipe to start with? This will be for 3 rifles to test. CVA Cascade, Christensen Mesa and SIG Cross.
