A failure to plan is a plan for failure.
You’ve definitely got the point.So the "good side" would be bullet holes #3 and #10, as numbered from top to bottom or left to right? These would be the loads to develop?
Also, do you have any examples of ladders shot @ 600y with the same loads? I'd love to see how the two methods compare visually.
Be in a part of the graph where increasing powder charge creates a lower POI on the target. That’s “the good side”.
Sometimes when you do this, you’ll find a place where the increase in powder charge doesn’t produce any change in vertical. As long as that is in the middle-ish of the good side, it’s a great load.
I’ve admitted to a short range bias. I’m not as good with the mid-to-long range. My work to date has been to do this style of tune, look at chrony numbers for low SD, followed by a traditional ladder to confirm things at the range that I’m going to compete at. Ya gotta take this part with a grain of salt. I just do not have enough experience at 600 to 1,000.
