RE: Nickel plated brass...good or bad?
Thicker brass will cause higher pressures. One of the old rules of thumb for the .308 class of cartridges was to reduce the charge by 10% of the difference in case weight. I don't know if the nickel brass is heavier or not . . . but I agree with Rebel Hog - stay away from it. The only application I can see would be a hunt maybe in coastal Alaska where salty air corrosion was an issue, and you weren't going to reload the brass anyway.
