    Ladder Test

    Please can somebody explain this in words of one syllable. Noticed mention in a couple of other threads. Seems like a good way to work up new load, but how do you do it and why does it work. Thanks in advance.

    I've posted about my attempts at this before. I used this article as reference - the two challenges I found were:

    finding a spot where I could shoot at long range (400 - 500 yds);
    working out which bullet hole was which.

    I shot at the attached target firing one round per bull, then moving forward and marking it up. It's not easy to follow, so I graphed it. I have attached a graph but it doesn't match the picture as I couldn't find that specific graph.

    The 260 Rem load I've shot in competition with this year was worked up by trial and error with most tests shot at ~150 yds and revisited again and again. I did do a test of the load at 400m before I competed with it. It's the first summer I've only used one load in competition.

    If you want to see more of the details, come round some evening.

    Best regards

    Dont know if you have also considered the OCW method also?

    I've had amazing results using it.

    Heres a link:

    +1 on the OCW method - use it to develop for all people I reload for.

    I found that previously when I used the Ladder method (which really relies on shooting at distance) that other variables crept in such as the wind and shooter error + it was a long way to keep returning to the target to mark bullet holes.
