I was wondering if anyone has experimented much with IMR 4064 powder in the 6.5 CM or a .260 Remington. I have 1 of each rifle and both love a charge of 38.5 grains of 4064 under a Hornady 123 SST bullet. I am getting .350 3 shot groups with pencil barrel Savage 11 and Axis II. Close to max loads that I can find and no pressure signs yet.
