Never noticed much of a difference with pistol brass like 38 Spl.,or 357 Mag. in regards to nickel plated vs. non plated. The most experience I had with rifle brass was years ago when I had a bunch of nickel plated .30-30 brass and it all seemed good. I was always waiting for some of the nickel plating to start chipping off like I heard could happen but have never experienced it. IME it seems to be a non-issue.
