I haven’t reloaded 45-70 in maybe 20 years, so it’s like starting over.
I will be roll crimping ( lee die) as a separate step after seating. The brass I have was trimmed back when I used a rcbs trimmer, and is not as uniform as I get now with l.e. Wilson set up. I have three lots of brass (50 pieces each lot). Each lot has 88% +/- .003 in length. The other pieces are equally longer and shorter
I will be shooting this in a Marlin lever gun so I do want a crimp.
My question is how uniform does the length need to be for a good crimp?
(note: original post had +/- .0003 in length. I edited to correct)
