First off I pick a projectile that I want to use, typically for hunting. I then pick a powder that will be suitable and hopefully have it in stock. I then do a ladder test to find the velocity node that I can live and look for a possible accuracy node
Then a do a few 3 shot groups at 100m with different charge weights around where I found my accuracy node. I usually stop here as I've either found a good load with a low sd/es OR I find something I don't like and it's back to the drawing board. Sometimes I mess with seating depth but a lot of my rifles it's just mag length.
I've found this to be a good recipe for success and takes the most minimal amount of components. Can usually fi d a good load in 25-35 rounds then I'll load up a bigger volume of them and prove them at distance.
Once I find a load I like a new component comes out that I have to try or i get bored with it and its back to the drawing board to rinse and repeat.
I do pretty much exactly this for all of my hunting rifles. The only time I get a bit nutso is loading my .223 for accuracy or loading a Weatherby, where I will compare book COAL to mag box COAL and see what does best (starting from book starting loads). That keeps it fun and "not a chore". Focus on the fundamentals and find something I'd be happy to hunt with, then spend the rest of the time practicing instead of chasing single digit SDs and ragged one hole groups. I like those, but reserve that effort for only one of my guns.
