7-300 win mag AI

Finally tested this baby.
Stiller action; Mc Crees folding chassis; 28"McGowan 9 twist barrel.
wanted to run it through the chronograph.
I am shooting the 162gr a max with 82 gr retumbo.
velocity for 4 shots was:
1-3392
2-3418
3-3401
4-3392
I will do a seating depth test in a week or two and see if I can dial it in.

    think you may have that figured out, where you shooting over the chrony when you shot the seating groups? you plan on shooting any of the bigger stuff out of that? i would be interested to see what it would do with a 180 berger. I am running the straight 7-300 win with a 180 at 3140

    I wasnt shooting over the chrony.
    I just used the 82 grain load pushing the 162 s at 3400 fps
    I am going to shoot the 162gr at 1000yds and see how it does.
    If I get the results I'm expecting I will stay with them.
    I have a few hundred of them so will try to stay with them for a while.

    Nice groups. Looks like you found a sweet spot around .09

    If berger ever releases the 190gn you definitely have a gun for it!

    I'll try to get out to the range a bit more.
    My next test will be at 600 and 1000yds
    If you want any more info let me know.
