    6.5 Grendel Field Challenge

    This is something I've been thinking about after my last outing with the Grendel.

    Basically, I want to start a fun challenge where we see what our capabilities and limitations are with our rifles, given realistic conditions, time constraints, and different classes of rifles.

    You have two main divisions:

    UKD- Unknown Distance

    KD- Known Distance

    For UKD, you take a 12" steel plate out to an unknown distance, the farther it is, the more points allotted. Set the plate in, ensuring you have a clear line of sight to it from your shooting position.

    Walk back to the position. On a shot timer, with your rifle in hand, hit the start, then get into position, determine the range to the target, account for your trajectory and wind, and make a 1st-round hit on the target. Use a 1 minute par time.

    The number of yards = number of points
    Number of seconds not used out of 1 minute = points
    1st round hit = 100 points
    2nd round hit = 50 points
    3rd round hit = 10 points

    Standing Position = + 100 points
    Kneeling Position = + 80 points
    Seated position = + 50 points
    Prone or bench position = + 0 points

    The shorter your barrel is, the more points you get:
    24-28" barrels = 0 extra points
    20" = 5 points
    18" = 10 points
    16" = 15 points
    14.5" = 20 points
    12.5-13" = 30 points
    10.5"-11.5" = 50 points

    For Known Distance, follow the same procedures, however, use an 8" target. This is for those who don't have access to open terrain where they can set out targets, and are limited to what is available at local ranges.

    In the example I did above.

    555yds estimated = 555
    1st round hit = 100
    Prone position = 0
    18" barrel = 10pts
    Total = 665pts

    I didn't time mine, but will do so next time I run this drill. It's inspired by Roe's Long Range Blog.

        I like the challenge Paul! Maybe give extra points for iron sights or scope magnification. That could help mitigate the distance limited folks like us in Southern California.

          I think I will incorporate this into my warm up for weekly training sessions- love it! I guess I will wait for my 16" LW barrel get in though...

          edit: i didn't do so well at RE milling the target- something to tighten back up!

              If you can record it on video, even better.

              Take pics at least.

              We need dome type of validation of performance, video really being the best way to do it.

                I guess I will have to make the boss upset by spending some cash on a camrea so I can play at this new game.

                Sounds like a cool challendge LRRPF52.

                  I'm in. My work schedule has changed drastically so I will have more time to learn how to shoot, compition always helps.
                  Great idea.

                      I'll probably try it with night vision. Probably about 1/2 the distance you day time shooters are using.

                          Great idea! Still waiting on my upper from Radical Firearms. It's been six weeks. Hopefully soon.

                            I completely forgot about this. Life got in the way this spring and summer
