I don't load for speed, Ioad 100% for accuracy and consistent powder charges so I'll never have anything but a single stage and don't want anything else.
I have a Rockchucker and a Redding T8 Turret press. I hand prime off press with a micrometer primer setting tool or an RCBS hand primer and I use custom made John Whidden bushing dies or Redding bushing dies only.
I use busing dies to control neck tension and of course I anneal my cases after every firing (pistol cases as well if the crimp is heavy, keeps them from neck cracking. I se an Annealeze.
I Use a Harrell Culver powder measure and and an Ohaus triple beam powder scale with a custom built powder trickler that has an adjustable electric eye the controls a cell phone vibrator unit that shakes a small plastic powder cup and feed tube. It's final charges very consistently within 1/10 of a grain all the time. Set mu culver measure to throw under at 1/2 grain and let the trickler finalize the charge
All my cases get tumbled in STS, no exceptions.
I'm picky, very picky but then I'm loading for downrange accuracy, mostly bottleneck case, not straightwall and I totally ignore SAMMI loading specs as well as overall cartridge length. Set mine for accuracy and dial my charges by how the cartridge shoots and I always check for brass wipe and hard ejection.
How I roll. No progressive stuff here, never will be.
