After years of procrastination, I am finally setting up to load for 45-70. I bought a Ruger #3 in 2015...still haven't shot it yet Back then, I did bought a NOE mold for it, then sold it as I decided I didn't like the design. I did cast a bunch, before I sold it, so I will be able to try them. I have recently ordered another NOE mold (clone of the Lyman 457483, no longer made by Lyman), that is more to my liking (more on that mold at a later date, and in it's own thread), but that mold hasn't arrived yet. I have the Lee 340gr FN mold, that is the boolit I will be working with later today or this weekend.
Some time ago, I bought a old RCBS 3 die set (date code G, circa 1956) and the dies have some surface rust on them. Currently I have them soaking. Luckily there is no rust in the Sizing area of the FL sizer die, and also no rust in the crimp area of the seat/crimp die. None of the rust is the severe pitting type, it's just the shallow, ugly surface type.
So the question is,
Do I completely de-rust the dies (with chemicals and/or electricity)?
OR
Do I just clean them with oil and denim cloth, and maybe oil and gentle "hand-powered" wire brushing on the knurling (to leave all the vintage patina)?
I imagine some people will just say, it's a personal preference. So, while I do like patina/rust-stain on vintage tools (I have a pretty good collection of old tools, thanks to my Dad and both Grandpas...plus some that I've acquired plenty auctions and garage sales), I also like shiny and new looking tools, because who doesn't?
Which way should I go?
