Good morning Fellas.
Boys, I am shooting a .45-75 Winchester repro... and my supply of brass has to give out some day. Up here in Canada the brass is like hen's teeth - and while it can be brought across the border - assuming there are still sources for it... it gets very, very pricey.
I'm told that the 50-90 brass can be formed into .45-70 and about the only road block I see for me - is turning down the neck diameter. Do I need a lathe for that? Is there a quick and dirty way to do that?
Also, I will have to trim the brass I have at some point. I have the RCBS trimmer and none of the shell holders fit. Can I file the case down, do you think?
I don't have a full blown machine shop, so any advice you fellas can spare would be sincerely appreciated.
Cheers!
