You load a bunch of rounds in .5 gr increments, and shoot them all at the same target, as you increase powder, they will walk up the target, but at some point a few will end up at the same vertical axis, which is, in theory, your rifles "sweet spot". Basically you are looking for the same thing as in the dan newbery method, several bullets of different charge weights that group together, except you are only worried about vertical grouping at this point. Once you have that 1.5-2gr range where they group vertically, you start loading 3-5 shot groups in .2gr increments in that range.
