The answer is yes and no.
Make sure you lube those nickel cases properly, and don't overwork them by sizing them up or down too far.
The problem is that the nickel flakes off, and if those tiny flakes or super-hard nickel get inside your sizing die, they'll get embedded in the steel. Every single case after that will get scratched. If the flakes are big enough, the resultant scratch can be deep enough to weaken the case. That's very bad.
Trimming, chamferring and excessive size/expand work all create nickel flakes.
Those things are great for the factory loads, but not so good for reloading.
