Re: Ladder Test

I don't really care about velocity that much, 3300 is plenty to make a gopher goosh, I just want to make bugholes as far out as I can. If that load won't get it done and you see somethin' in that shot string more promising, or have any other advice to give, please pipe up.

    If velocity is so important, does that mean that 10 is best? Sinc 9, 10 and 11 have only a 19fps spread, and 1 moa spread in windage and about 1/2 moa in elevation?

    I thought I saw a pattern with 1-3 horizontal stringing, 4-6 a tight node, 7-9 diagonal stringing, 10-11 horizontal stringing, with a likely node .5 gr above #11.
    Am I missing the boat?

    test loads 4, 5 and 6 to confirm repeatable groups and chrono results.

    Look for low SD and ES.

    Tweak seating depth last up and down.

    You did not mention the accuracy of your charges weight. beam or electronic Scale, thrown with measure or what, but that could effect the ladder if not right on.

    If loading for a magazine gun, always start at max OAL or if single shot start at a hard jam, and that you only have to work in on seating depth.

    I used a beam scale and trickled each load to right on. Magazine puts COL at about .001" off the lands.
