I don't know about .410 specifically but in other gauges you need to know the number of "points" the particular hull has for crimping. I.E. some brands of shells may be crimped with 6 points, others with 8, etc. If you try to reload a hull that originally had 8 points and you are using a 6 point crimping die, it won't fold right and might not stay closed and vice versa. Therefore, shotshell reloaders will sort their hulls by the number of points needed and then swap out their crimping die to match the hulls they are reloading at that time.

All this is to tell you that one crimping die probably isn't going to be enough.
