IMO, loading .223 on a progressive should be done in two passes.
First pass....size and deprime.
Second pass....prime, charge and seat the bullet. I've never had a need to crimp.
What has worked for me in the majority of 150,000 rounds is to have 2 toolheads. The first has a Lee Universal decapper in station 1 and a Redding fls die in station 2.
I then trim, chamfer and deburr in a single operation with a Bertlesman trimmer. I trim after every firing to minimum spec. This removes the need to measure and chamfer after every firing.
I then tumble to remove sizing lube.
The second has a Lee Universal decapper in station 1 to remove any media in the flash hole. Station 2 has the powder measure. Station 3 has a Lee Universal decapper that has been modified to act as a powder checker. Station 4 has the bullet seater and station 5 is empty.
I actually use a third toolhead for 500/600 yard match ammo. The only difference between it and the second one is that it has a manually operated Harrell powder measure on it instead of the Dillon measure.
