Loading 45/70 cartridges with 45/90 dies?

As the heading says. Can it be done?

You will probably not be able to crimp your bullets due to the die being too long. If you are shooting black powder in a single shot, a crimp may not be desireable.If you are shooting this in a Winchester 1886, Marlin 1895, or converted Winchester 71 you will need to crimp regardless of what type powder you use.

You're best bet would be to get a new die set, although you may be able to get by with what you have.

I've got a Lee 45 Crimp Die that i use with my 454 Casull reloads.

Your Lee Pistol die may not work because it is for .454 diameter and your 45-70 is .458.

+1 using a 454 casull crimp die will probably not work. I would think if it did crimp your cases it would be excessive or it may collapse your cases.
