If you mean the nickel cases then yes. Are they pistol or rifle cases? The pistol ones go through a set of carbide dies like butter. I don't recall reloading any nickel rifle cases, but I would imagine that they would be slick too.

I couldnt think of the right word for those shells "nickel you bone head" Ok I have never tried them so I'll see what they do
They'll work, but the nickel is harder than the brass so a) make sure they are darn clean or they may scratch your die, and b) you'll get fewer reloadings because the nickel will start to come off.
