YES

Yes, errrr, I mean No. I doubt if you will notice any difference. You will probably find more difference in volume between brands or between lot numbers than you would find between plated and naked brass. Whatever you use it's always a good idea to weigh a few cases and/or weigh the volume of water they will hold to see exactly what the differences, if any, are. Best bet is to drop all charges a couple of grains and work back up anytime you change anything.

The difference between nickel plated cases and regular unplated brass cases is unbelievably small.

The thickness of the plating is about roughly 50 millionths of an inch. Forget it...it's nothing to concern yourself with.
