I've use nickle plated brass in several instances where identification of two calibers can be difficult because of headstamp markings (ie; 25-06/6.5-06 & .257BobAI and 6.5-257 BobAI) I have also used it on a .243 to prevent my grandsons from mixing it with the .260 that they also use...(a .260 will not chamber in a .243 but bringing the wrong ammo in the field will end your day and rattling a .243 bullet down a .260 bore probably won't hit its mark).
Nickel plated brass in the calibers I use seems to size with somewhat more effort so good lube is as important or more important than with brass..
Contrary to popular belief Nickel plated brass will not "scratch" dies...However, nickel being a little harder than brass can allow contaminents to embed in the plating and possibly scratch dies...Extra care must be taken to keep cases clean prior to sizing...(The same contaminents in brass might/may "sink" farther into the brass being it is softer and not scratch dies or scratch as bad as the nickel plated stuff)...
On the other hand nickel (being a little harder) might wear dies more in a given sequence of sizing repititions than brass...But who here has wore many sets of dies out in the first place....I have upgraded a few sets over 50 years but can't say I have ever wore any out....I have however scratched a couple and not with nickle but with dirty "brass"...
Keep the nickle clean and lubed, you should have no problems.
