Well, heaven forbid that I be the one here to disagree, but...
I have been reloading nickel brass for my handguns since '86. I purchased a bunch of once fired .38 Special brass in '86, 1k, and about 25% was nickel. I also have a few hundred nickel brass in .44 Magnum, and .357 Magnum. I have reloaded some of the 38s enough times to wear through the plating (Federal, Winchester, RP and others). I flare all the mouths to accept lead bullets and 90% is roll crimped. I have never had a case failure due to nickel plating; no flaking, no abnormal die wear, brittle case mouths, etc. I only have about 1,000 nickel plated cases all together, and I don't count how many times they have been reloaded (I've been reloading almost steadily since '86 moatly .44 Mag. and 38 Special). I don't purposely forgo reloading nickel, I just grab a box out of the brass bin, plain or nickel, and so far there is little to no difference noticeable. Mebbe I just got the only thousand good nckel plated cases on the west coast... :mrgreen:
