    Hornady 123 SST Factory and AA upper

    I finally got to the range to sight in my Grendel for ground hog hunting.

    Alexander Arms 6.5 Grendel 20" Entry upper on a Rocker River Lower with a RRA two-stage match trigger.

    Leupold 3-9 Mark 2 scope at 100 yards in a gusty wind. I think the third shot opened up the group because of target movement. The orange dot is an inch.

    Average velocity of nine rounds was 2644.44 with a SD of 22.43.

    I'll think it will do.
