As someone does my annealing on an AMP sometimes they've only been cleaned on tge outside and a bronze brush span in the neck and sometimes they've had a full prep..
It depends on if I hand them over after the shoot is over or bring the with me for annealing..
If they've been prepped then there annealed I run them over the custom ground neck tension mandrel before loading..
I doubt it makes any difference as sometimes there annealed every firing sometimes twice so the brass will still be supple..
If I did my own then I too would clean,anneal and resize.
