Re: Nickel LC Cases
A lot of people don't like nickel-plated brass because the nickel can flake and embed inside your die. Once that happens, the die is toast.
That said, I have some nickel .357 Mag brass that I bought in the mid-1970s. I've lost a few pieces due to split case mouths, but I've loaded that brass at least 15 times - off the top of my head. It's 8,000 miles away, else I'd go check.
