    gday all just had one of them days the battery went flat in me crono and i don't have a whiz bang phone so no way to calculate bullet speed .

    can someone run the numbers please as i think the hornady Ballistics calculator says
    my load is 2960 fps and there was a comment the other day on here that that would be a very HOT load and in my sendero there is no pressure sings at all .

    easy bolt lift and plenty radias on the edge of the primers .

    2950 looks good to me. Puts you one 1/4 click off at both distances. One high and one low.

    thank you very much, as i said no pressure signs so this will be my load

    i don't have much trouble knocking off 3l milk jugs and the target shot was .714 moa

    for 3 shots at 700y . i just need more practice reading the breeze .

    cheers D
