First RUN A CASE INTO a SMALL BASE 223 SIZER DIE WITHOUT the expandrer/decapper. This will size the neck down and make it so much easier to do the final sizing. It takes a bit longer that way but the results, to me, look a bit more consistent. It also is just easier when you do the final neck down as you are able to feel the neck engage the bushing and you can ease it in.
Once done run it into a 223 Redding Type S bushing die with 225 bushing, or what size you want, chamfer and you are finished.
CURRENT METHOD ON MY BENCH
I set up my 650 with a DILLON 1200 trimmer and 223 die in station #32. I trim to 1.745 as the necks grow. Them in station #5 i have the 223 bushing die with a 225 bushing.
I use Hornady One Shot Spray. After the final size down I chamfer in and out and throw them in the tumbler. This gets the lube gone and any small brass chips. I do flash holes and primer pockets whenever I feel like it before I do the initial size/trim.
Be advised the DILLON 1200 is SMALL BASE We recommend a SB die for INITIAL forming as some current bras is very tight in the chamber that we cut to a minimum dimension. After that I just use the Redding Type S with a bushing.

Just because it is factory loaded doesn't mean it can't be improved on.
