OK, situation update: I bought the set of .41 Mag dies. Resized a .445 Supermagnum case in the .41 sizing die (well lubed) down about .30". No problem doing so. Then changed to the .40 cal/10mm sizing die, relubed the case, and completed the sizing down to where I did before. The case fits perfectly in my .44 Magnum chambers. Thanks for the advice to all! It worked like a charm.
