.22 EDgun R3 Long at 935 to 940 FPS, shoots about MOA at 100 yards. Very consistent. You can of course go faster, and retain accuracy, unlike a lot of diabolo shaped pellets. Perhaps because the RD Monster has a much longer waist and it shaped differently than other diablo shaped pellets. But you can't get away from physics no matter how hard you try, and the BC will start to decrease with them once you go much over 950 FPS...
