For Pistol
I'm reloading nickel plated brass only if I know that I'm not getting that brass back (i.e. IPSC match). I do not like using it as I've found that it cracks (splits) at a much-much higher rate than brass-brass.
Many times when shooting nickel-brass I've noticed the 'tincan sound' that a splitted case makes when hitting the concrete floor at my range, and it very rarely happens with unplated brass.
I believe that it has to do with the fact that nickel is harder and more brittle than brass, and it makes a composite material where cracks will propagate to the brass. (Feel free to correct my theory if it's wrong)
For Rifle
I'm only using nickel-plated brass on my hunting rounds, and this is solely for corrosion resistance. Hunting cartridges will get exposed to high humidity, rain and water.
One thing though, since I've notice a 'cracking' problem with pistol brass, I've never reloaded nickel-plated rifle brass more than once, so I cannot attest of it durability.
