To me, only the following makes sense for loading bottleneck cases:
1) use a single-stage or Lee turret (with auto-indexing). You only need a sizing die and a seating die. You remove the case after sizing and you trim as needed. If you remove the case from a progressive, you have saved nothing and spent a LOT of money. While off the press, you can trim, prime, and do any another voodoo you think will help. I have spent almost 45 years completely happy with a Forster Co-Ax.
or
2) you get a Dillon 1050 that can swage primer pockets on the fly and you install a Dillon RT1500 trimmer/sizer so you can ACTUALLY get some advantage from a progressive press for bottleneck cases and the press seats EVERY primer the SAME. Then you can go to a bullet collator...
