I may enjoy the reloading the most....If wealthy, I might just reload and pay others to shoot it
There are some people, like you, who want to build a display for their hand loads that has a plaque detailing how uniform each round is, and how many careful hours were spent making it.
There isn't a single issue with that. If you love it, do it!
But I like to shoot my hand loads, so I will use any time saving technique I can provided it doesn't significantly affect accuracy.
I am not an IBR competitor, so 1/20" groups isn't going to happen in any of my rifles.
I have been slowly figuring out what matters, and what doesn't make much difference.
So far I have found,
Seating depth consistency matters a lot
Annealing for consistent bullet hold matters
Neck concentricity matters a lot
Consistent primer ignition matters a lot
Weighing each powder charge is a waste of time if the powder meters within 1-2 tenths out of a thrower.
Primer lot difference is mostly non-existent
And progressive presses will make 1/2 moa ammo in my comp. AR, no worse than my single stage made stuff but in 1/6 the time
