I think I have a plan:
Have a spare tool head for the 550 that holds only decapping/resizing dies, switching the die that I want to use to station 1
Lube
Deprime/resize(cleaning the dies when necessary)
Trim when necessary
Wet tumble
Dry in dehydrator
Load in progressive mode with an empty slot in station 1(this station will still be responsible for priming)
Basically the gist is to put lots of care and attention in case prep and then "load the bases" on the 550B and crank away.
I thought about this some. Is there concern that you will deform the necks with wet tumbling? That is the reason I intend to decap ONLY, then wet tumble with pins, and then lube-resize-trim....
