    I got a little triger time today. Boy is it HOT ! 99.4 degrees under the shed that covers the shooting benches. The wind was blowing so hard it blew my target down . Not the kind of conditions that I hoped for but I was after the Average MV and the SD of a 10 shot string .

    Load 85.5 grains of Retumbo

    210 Berger

    Average MV from 10 shot string was 2900 FPS

    Standard deveiation 12.4

    I think most folks shoot 5 shots .

    but i shot 10 . I know we need single digits but would this combo get me started at longer ranges ? I put all 10 under 1 3/4'' @ 200 yards and the wind was blowing around 10 mph maybe harder at times.

    What do you guys think ?? lay it on me I got big sholders:D

    Thanks for looking........

    Good start!

    Things will refine as you go.

    Ten shot groups are a good test.

    Better test is 1 shot 1 day for 10 days.:)

    Remember, the wind is your friend.:D

    Thanks for the reply. I plan on shooting 500, 600,800 &1000 this week and see how close I can get with 1 shot at each distance . Then target validate...... and let the NF software adj. my actual MV.
