603Country, You've got 30yr experience reloading not sure I agree that you should change based on how others reloading.
I would get on Palma,BR and F-Class site's and see what's current and how they loading. I shot Br and results from the 1987 Super Shoot which is the big one there was winning groups low .2 and high .1's and small group shot was 081". this year they had I think 3/4 groups winning that were in the .1's rest were in the .2's so not much has changed.
Look at how the F-Class open shooters load vs Palma shooters today not lot of different.
You also have to consider match rifle vs factory. I shoot some pretty nice chamber rifles so I can skip some step that I might do with factory rifle.
