[QUOTE="fisherman987, post: 1945385, member: 107270"] Generally speaking, when you are looking for the optimum charge weight, you are looking to find a range of charge weight where there is very little verticle spread between your bullets without being worried about horizontal spread which is much more influenced by wind etc. This is why you perform a ladder test, so you can see where the bullet impacts begin to group along the same vertical plane. After that, you adjust seating depth to find the tightest horizontal, then go back and tweak the charge and any other things to achieve best tune. General rule of thumb is to isolate individual aspects of your tune and only change one thing at a time so you can actually know what your changes are accomplishing, otherwise it gets very confusing and frustrating. And to more directly address your question, you have three shots all on the same vertical plane even though they have a lot of horizontal. At this point, we don't know if the wind was all over the place, if the shooting techniques cause left to right etc. But since those three shots came from a broad charge weight and all hit on same vertical plane, that would certainly be a place to explore for accuracy.
