45-70 roll crimp

My RCBS Cowboy dies in 38-55 make the best roll crimp I have ever used, I wish my 45-70 dies were "Cowboy" model.
My regular RCBS 45-70's will crimp but are more sever in their action and harder to set for a perfect crimp. Another plus for the Cowboy set is that they come with two sizes of case mouth expander balls, one for jacketed slug dia and the other for cast dia.
 
Just saw this on fortunecookie45lc you tube site: Lee micrometer bullet seating die. A recent addition to the Lee reloading die collection.
According to fortune cookie, this die can also serve as a hack to create precision crimps.. Which may be useful, in your case.

He demonstrated it on 9mm cartridge. To show how easy it was to get a good, easily repeatable taper crimp. But, may also work well for roll crimps, too. The die is available over a wide variety of calibers. Including, .45-70.

Easy to use. Screws onto existing Lee die. Provides precise control of bullet seating depth. May also provide precision control of crimp. I can see where this would be a great benefit with cartridges that are sometimes finicky to crimp...ie: 38-40, 44-40 WCF.
Or when returning to a previous bullet seating (or crimp) setting. Allows for easy set up

Not sure whether this may be of use in your case, but might be worth a look.

By the way, though I've used both RCBS and Lyman 45-70 dies in the past, I've found that the Lee factory crimp die delivers good results. I use mine with lead bullets in .45-70. No issues. Gives me a good, firm crimp.

Will be looking into this Lee die myself, in the near future. Can already see where it would come in handy.

I agree. My Lee works great for my 405 cast loads
 
DancesWithEmptyCasings: I'm pleased with the crimps, too. Very firm and consistent. Over a variety of cast bullets, ranging from 400 to 500 grains.
One thing I like about all the Lee factory crimp dies is that, the ease in which the crimp can be applied or adjusted. A very simple and efficient setup.
I do like the Lyman M-die, for case mouth flaring though, and tend to prefer it over the Lee flare die. Though it works well, too. I always seat bullets and crimp in separate operations. Provides far better control of the finished cartridge, in my experience.

Still, there's nothing wrong with Lyman dies. Have had plenty of success with these, over the years. As well as RCBS. Have a handful of Redding dies, too. Pricey, but worth every nickle.

I suppose that in the end, any of the die brands mentioned in previous posts, should handle the job equally well.

Could try soaking it in evaporust to remove the rust then polishing it afterwards
As for the crimp I agree with the others saying to use the Lee factory crimp die
 
who makes the best 45-70 dies for loading lead bullets? my old redding set is about had it. lookin to upgrade

I've tried a few different brands and have settled on the RCBS cowboy set (for lead), and a Lee factory crimp die (for lead and jacketed) when they're going in a lever gun with a tube mag. For the Sharps, I don't bother with the Lee crimp - just a very light roll crimp on the seating die is all that's required.
