Took my problem child Grendel to the range again today. I think Im finally figuring out what this thing likes. I was using Varget today and fully expected to get way too low a FPS for what I want to do with it but I had it on the shelf and my gun simply wont run on AR Comp and CFE 223 is too temperature sensitive for my tastes. But it surprised me and I may stick with Varget and just tinker with other powders to see if I can get it to shoot good and get more speed. I realize these are only 3 shot groups but I was trying to save bullets and powder and I will go back and shoot the good groups again using 5 shot groups just to verify.
