Jim,
I'm going to start making these what I call local matches, Rapids, Merrill and Alma as well as Harris a priority. They are relaxed and fun but I do wish that they could be longer than just a one day match and set up where you have time an afternoon before the match for getting sight settings and getting some load trials. Getting sight settings for a short period before the match is fine but a 1/2 day would be better
I have come to the conclusion shooting all these ladder test loads over time that the bullet profile has more to do with accuracy than anything else.
Having a load with a particular powder charge that puts a consistent good group just changing the bullet with a different shaped ogive but the length, alloy and diameters the same the groups will change to the better or worse.
