    Load Progression Data: 123gr SST, CFE223, 24" Overwatch, Suppressed

    FINALLY got to go to the range and do this progression again with the can affixed.

    Here's the data...

    31.5gr:
    5 shots
    Mean - 2627
    stdev - 19

    31.6gr:
    10 shots (2x 5 shot strings)
    Mean 1 - 2625
    STD 1 - 31
    Mean 2 - 2583
    stdev 2 - 35

    31.7gr:
    10 shots
    Mean - 2630
    stdev - 19

    31.8gr
    10 shots (chrono only picked up 8)
    Mean - 2662
    stdev - 13

    31.9gr
    5 shots
    Mean - 2651
    stdev - 7

    32.0gr
    5 shots
    Mean - 2646
    stdev - 11

    Numbers were all over the place!

    The 31.5gr load seemed to have the best grouping. Though there was a 3.5" POI shift from the last shooting range trip after putting on the suppressor, the 5 shot string put one single long jagged hole in the paper (as the barrel warmed up I suppose).
