It is very likely that your .44SPL dies are roll crimp dies. I suppose someone may sell taper crimp dies for the 44, but I wouldn’t know who it might be.
Factory Crimp dies for the 44 will be roll crimp.
As you can see above the only real question comes in the case of rimless auto loading cartridges shot in revolvers. Since they do not have to locate on front edge of the case, you have an option in crimping. Although you can have a really good argument about whether in practice semi-autos really space on that edge or are held in place by the extractor.

All that said, IMO you are better off crimping, whether roll or taper in a separate step after bullet seating. Thus the fourth stage.
