    Crow Mag,
    At sealevel using STP I beleive it's 1120.??fps.
    For 800ft it should be 1115.28 fps and at 6000ft altitude it should be around 1093.27 fps if I calculated it correctly. Now under actual firing conditions that most definitely will change because of different variables used above. It's not a constant.
