A little trick tat is helpful. Make a .030 or .045 shim for under the seat crimp die. Set die to proper crimp with out shim. Then when seating bullets add shim under it with out resetting the lock ring. This allows depth to be set and bullet seated. then remove shim and raise the seating stem to crimp. You can make this shim from shim stock or even banding.
For a .432 dia bullet I would look for an expander around .429. .002 is a lot of press on this size dia.
