I bought 1000 once fired Speer Nickel .223 Rem cases that I plan to cut to form 300 Blackout.

I'd like to anneal the cases after cutting. Most of the times that I've cut down brass for re-forming it hasn't been necessary to anneal them, but as Nickle cases start out harder, I'd expect to have a shorter life if I form and load without annealing.

Anyone have experience reforming nickel cases? Do you anneal? Should I just leave them as .223 Rem and stay with brass for forming 300 Blackout.
