I try and get baseline measurements of everything.
I do the Berger seating depth test with a mild load to start
Then I do a ladder test over a chrony looking for the nodes
Load up a few in the middle and try a couple different depths and shoot them over a magnetospeed again.
If the es is low and accuracy is good then you have a winner
If not then I tinker with depths, primers, .1 charge weights changes, neck tension etc
If it’s all over the map, not repeatable, es is high and won’t get better, or velocity is low or inconsistent. I pitch it and try something else
I don't bother with most of that, but I usually end up in the 1/2moa or better range, at 200m, and well under moa to 500m for average groups.
