I am processing .223

I have station 1 setup as a decapping station, with my RT-1200 trimmer set up at station 3.

How/when do I neck size my cases?

If I setup my other toolhead to neck size in station 1, then what do I do about lube when I am dropping powder?

are you decamping ONLY in station one, or full length sizing as well (which you ought to be if you're trimming...)?

also, if these loads are intended for a semi-auto, then I would recommend you forget about neck sizing...

The trimmer also full length sizes the brass. My concern is that the neck does not get sized if I am using the dillon sizing/trimmer die.

Does your sizer/decapping die not do both?

To size brass I remove all dies except for the sizer die. After tumbling the brass I lube it and run it through the sizer/decapping die. I do not have the RT trimmer so I have to trim, chamfer and debur with the giraud. I also clean the primer pockets and decrimp them before they are ready to reload.

Once my brass is completely prepped, I will remove the sizer die and add on the powder drop and bullet seater. I load the brass, prime, drop powder and seat the bullet.

Case prep of rifle brass for loading on a progressive press is a distinct process  in a two stage event.
First Stage
You must prelube and then you can have a universal decappikng die in station #1 of 550
You FL (there is no neck sizing die) sizing cases uisng the RT1200 if properly set up, and so now you have processed cases for FL sizing and trimming.
Now, you must remove case lube and and debris from trimming, I would do this by running the batch of brass through your tumbler to do this.
Now you need to chamfer and deburr the case mouth, deal with any primer pocket crimp, clean out the primer pocket, etc. Now you have prepped and ready to load brass.

Second Stage
Now, I would place your universal decapper die in station #1 to remove any errant debris from case prep, and then prime on downstroke.
Dispense powder at station #2
Seat the bullet at station #3
Crimp is so desired at station #4

ahhh i see.

So I do not need to resize the neck after going through the sizing/trimming die then?

No. The cases are already FL re-sized during the trim operation. If the brass is sized before the the trim operation the case won't be held and will spin in the trim die and make all kinds of racket.

You also don't need to champher unless you are loading flat based bullets. After you've cleaned your brass set the size die in station 1 to only run the expander ball down through the case mouth.
