Help me out here. In every description of the various versions of ladder and OCW load development methods I have seen, conventional wisdom says to ignore any horizontal distribution and attribute it to wind. We all know barrels oscillate upon firing but what law of physics makes them only oscillate in the vertical axis? Why don't they oscillate in the horizontal axis too? Or in a combination of vertical and horizontal axis? And, if that is the case, why are we ignoring the horizontal dispersion in ladder and OCW type load development?
Thanks,

Now that we have 3 pages of shared knowledge, Lets start again:
If you have a 20 shot ladder at .1 gr one shot steps and you find a 3 shot point (+/- .1) that is very good vertically but not horizontally what are you going to do about it?
