The roll crimp serves 2 purposes. To help slow burning powders build pressure for efficient burning and to prevent bullet jump under recoil.
In light range fodder with fast powder I just put enough taper crimp to make sure all belling is gone. My revolver seating/crimping die is a roll crimp so I back that off and apply the taper with the LFCD.
