A good turret press is NOT just a place to store dies while you run all the brass through one step at a time. The Redding is a beautiful piece of work.
For efficient loading with a turret press, I find the following procedure to be extremely practical.
Place the dies in the turret in the same order as the operations need to be performed. To load straight-cased handgun ammo such as .357 or .44 Mag, for example, start by installing and adjusting the sizer for its sizing-depriming-repriming function.
Then rotate the turret to the next station and install/adjust the expander (or "flaring") die.
Now, install the powder measure in the next station....RCBS (and Lyman, I think) measures are threaded 7/8-14 just like the dies. Adjust the measure for the chosen charge and LOCK THE SETTING with pliers or even a small pipe wrench. This will absolutely prevent the setting from changing as a result of vibration. Ensure the measure's handle is positioned to clear the dies as it's being cycled.
If you're using a four-die set which seats with one die and crimps with another, now is the time to install the seater, followed by the crimp die, each of them adjusted as required. With a three-die set, obviously the combined seater-crimper is installed and adjusted in the station after the powder measure.
Now, LOCK all the stems and lock rings tightly.
In use, the case is sized-deprimed-reprimed, and the turret clicked to the expander step for belling, and then rotated to the powder-charging operation. Visual powder inspection is easy and you are only dealing with ONE case, not a blockfull. Occasionally I try to loosen the powder measure's locknut with my fingers, just to be certain that it's NOT moving. Charge weight is checked occasionally as well.
With the charge in the case, the turret is turned to the final step(s) of seating and crimping, and ...Heavens to Betsy... we have a LOADED ROUND about twenty seconds after we started production!
Instead of processing several hundred cases through each step, and taking a LONG time before actually producing a single loaded round, we only have two types of cases:
-inert, fired, dead-empty, ready for loading, and
-newly-loaded ammunition, ready to shoot.
We do not have a bunch of brass at some half-way point in the sequence, useless for anything as it sits, should the session at the bench be interrupted for some reason.
Due to greatly-reduced numbers of hand operations, considerable time can also be saved without rushing things. On my forty-year-old Lyman All-American, it's easy to load 150 to 200 rounds of handgun ammo per hour, safely and as mentioned, WITHOUT rushing at all.
I love my Rockchucker for many purposes, but compared to the turret bolted down beside, it the single-stage is painfully slow. When I bought the A-A turret back in the '60s, the contrast with my single-stage was so dramatic that I thought I'd gone to handloading heaven! We were shooting a lot of Bullseye Pistol competition and what a Godsend the turret was to me.
The turret is not just a place to store dies conveniently. Once the dies for each caliber are properly adjusted and their adjustments LOCKED, they can be removed from the turret and stored in their boxes, ready to be quickly re-installed the next time they're needed, and needing only very minor tweaking (if any) before resuming efficient production in that caliber.
Used in this manner, the turret is a useful intermediate-speed machine which splits the difference between a single-stage and a progressive. My Dillon 550 sits on the other side of the A-A, away from the Rockchucker. All three presses have their uses, but the turret sees the most hours of use by far.
