Get a TC barrel from their Custom Shop or other custom barrel makers.
Grab a set of dies. Just the reloading ones, not the forming ones.
Call Lee Precision and get a .30 Luger/Mauser sizing die.
Lube the .357 Mag brass with Imperial sizing wax. Use the .30 Mauser sizer to neck the mouth down to .30 caliber. Not too far down, maybe .125 inches down. Then use the .256 full length sizer die to finish the job and set the shoulder. Trim to length. I've been loading like this for many years and never split a case yet.
The first time you load it, it will have a slight radius to the shoulder. Don't worry, it will fire form your first time you shoot it. Best dies are the Redding deluxe dies with the FL sizer, neck sizer and seater. Use the FL sizer as above for the forming process but then neck size only after that. When it gets tight to chamber use the FL sizer die to kiss the shoulder back until it chambers again.
If you get set up for it, PM me and I'll send you a few pieces of formed brass to use as a guide for setting your dies.
