This helps answer my questions, thank you.In my opinion, initial group size (at an acceptable level to you) is best determined with coarse tests with primer/powder combinations.
If I can’t get groups under 1" in 10 shots (ladder), I switch to another powder.
"Tuning" a load means making small changes to get small results.
For me, at least, that means going from 0.7-8" groups to maybe 0.4-0.5" groups. Jm2cw.
This assumes your barrel/rifle is capable of shooting "small" groups.
Sounds like in your experience fine tuning yields up to, say... 0.4moa improvement. So essentially we should be examining our initial rough (ladder) group size as a metric for switching powders/primers/bullet before fine tuning.
