It may not be the "best" but I get what I want out of IMR 8208 with 120s. Depending on the bullet 2500 to 2550 fps with 18 to 20" barrel. I have not really had the time to do much trying of other powders because I just started with the Grendel this past spring. Just found me a good deer hunting load with both my rifles and wanted to try two different bullets, Sierra PH and Speer GD. Things did not work out to allow me to shoot but only one deer with the 120 Speer GD at 2550 fps from the 20" barrel. AWESOME results. I have a bunch of different powders, been hand loading for 40 years, and some lighter bullets I am going to give a work out this spring and summer. I did try to find a load with Hornady 123 SST but neither of my rifles like this bullet. Could not get it to shoot under 1 1/2" except with one load of IMR 4895 and that was the only group I shot with it and never had the time to give it another try.
