I'm loading rounds for a Saturday 600yd match right now.
My sizing ends with pocket up, I measure length and flip the ones that need trim ( I get growth with my 22 Nosler AR) , chamfer/deburr leaving neck up (can see shiney neck).
Prime, leaving primer up.
NO powder can spill into cases.
Then one at a time charge/adjust up/down slightly/seat.
I can stop at any time and tell where I left off.

I did a ladder last practice session with a new barrel and don't have time to do another before the match.
3 charges seem to hold promise, so I'll combine load testing with the match.
32.1 gave an average of 2996fps. (Magnetospeed) loading 32.0 for couple foulers then 32.1 for 24 rounds,
31.7 gave a 5 shot average of 2944, loading 31.6.
31.1gr of SB 6.5 gave an average (5 shots) of 2890fps
Starting with the higher load, and maybe clicking up 0.1 mil for each relay with the smaller charges.
Loaded some more, nap time
