Here's my take on all of this:
If you're super concerned about 100% brass fit into your chamber, you need to order a custom die to match your chamber.
Lots of gunsmiths are capable of doing the job. It's expensive, but it does the job 100%.
Another option would be to use a Forster die and have the neck honed to match your preferred loaded neck diameter. You can control shoulder sizing with Redding comp shell holders.
You can buy the SAC modular die and play around with it until it either fits, or you pull your hair out.
Buy the Redding type-S or Wilson and use the correct bushing with the understanding the die was designed NOT to size the entire neck.
Buy the Harrell's and get everything the Redding and Wilson do, with the added benefit of custom web area (AKA the .200 line) sizing.
Buy off the shelf RCBS, Lee, Hornady, Redding, Lyman or Forster dies and simplify your life.
Buy whatever crazy combination the Ewe-Toob expert says you need and size, trim, chamfer, deburr, anneal, neck turn, wet clean and mandrel for neck tension to your heart's content.
Most of the above doesn't make enough of a difference beyond our paper sight in distance because people can't read the wind and mirage well enough to use the minor changes these steps make.
I've gone through most of the above time wasters.
I've gone back to the basics, done correctly.
