Spoke to a fellow and very experienced shooter today and he recommends Silhouette. He said SP2 is the BEST but you cant get it anywhere. With that, i'm thinking of trying to develop a load with Silhouette, MG 121grn IFP and WSP primers. Based on all the chrono data here, i think it is safe to start at 7.4gr. I will post results when i run my test.
