    I ran this thru RSI's Shooting Lab software.
    You didn't mention one parameter that mine wants to know and that is relative humidity. Shooting Lab defaulted to 78% and I just left that alone. All other parameters were as you specified.
    Here are the results:

    250 yards: Drop is 12.82 inches and path is -2.51 moa
    500 yards: Drop is 58.94 inches and path is -8.68 moa
    750 yards: Drop is 154.98 inches and path is -17.09 moa
    1000 yards: Drop is 328.60 inches and path is -28.71 moa

    Hope I did it right. First time I have used this software. /ubbthreads/images/graemlins/smile.gif
    I just got it with my new CED Millennium Chronograph. Actually I have had it for a year and a half, but I've been so busy with work and all it's going to get it's first range test either tomorrow or next week. Sad huh?
