I was just wondering what type of grain R15 is and how well it meters. Speer 13 frequently has it as one of the top powders for .308 with a variety of bullet weights. What kind of shooting results have you had with it?
Also, how well does SR4759 meter? Since this will be for reduced .308 loads I'm not exactly worried about bench rest accuracy, but at the same time I don't want greatly different charges if I reload these on the 550.
Thanks
Jack
