I am a little late to this thread, but I figured that I would put my load data out there since I have had a horrible time trying to find much information myself. I am using norma brass, with hornady 220 eld-x bullets and H1000 powder out of a 22" Proof Research carbon fiber barrel. I have been using 84.2 grains and getting 2864 fps on my five round group. I had tried one load group at 84.6 but I didn't like the 5 shot grouping so I never tested it for speed. I am thinking about tinkering a little to get to the 2950-3000 range right now but I haven't been able to find any good load data from others to go off of yet. I am new to all of this so a bit hesitant without other's load data.
