I have a SEQUENTIAL reloader, not some Commie "progressive" reloader. It's a Dillon 650. TAC is a fine powder for that weight of bullet, too, and pours well out of the Dillon measures.
But I never FL size and load at the same time. I will lube, deprime only, FL size only, expand only, on die stations, then tumble pretty. Reset the machine, then prime/pour/seat in a second trip through. Had too many stuck cases/tearouts trying to do it all at once. The other issue is "ride." Smooth is good, and the variations in the amount of lever force needed on FL sizing affects how charges get thrown. It's not a lot, but shows up as a group-size penalty, probably 30 percent larger. But it's the stuck-case rigmarole that I hate the most. I just run the FL die "naked" with no guts inside. Then if I jam up, all I have to do is unscrew the die, get a beefy drill rod into the case mouth and whack the case out of the die. Reinstall and go again.
