I got a friend into loading and now casting figured i would share his results. First off we are casting using a new arsenal mold no lube grooves and drops at 220 he is powder coating them comes out at 57 grains and sized to 224. First gun tried was a 7.5 inch ar using h335. He started around 19 grains working up to 24 grains, the short barrel wouldn't burn all the powder and caused a ftf wouldn't chamber cause of the unburned powder. I told him just out of curiosity try them in the 16 inch for function he started again with the loads above he ended up with a 1 inch group at 65 yards with 24 grains of powder. I wouldnt have thought the loads would work that good but now we are thinking about the 3006 and pushing them with full loads . He has checked the gun no leading or fouling at all. I figured I would share his results, hope this helps someone out.
