Nickel cases will not tarnish like brass.
I suppose if you hunt in extreme conditions it could be of a benefit but brass will last decades in my hands before it pin holes through from the elements if it ever does.
I do not hunt in extreme enough conditions.
I have annealed rifle cases that are nickel plated.
They do NOT change colors like brass so either use tempilaq or Sharpie brand marker or the finger method.
9-13 seconds in the flame is usually plenty depending on what size case.
I would load and shoot them and if accuracy was poor and you felt uneven seating pressures during the seating of the bullets then I would explore annealing them.
During my recent brass fail test necksizing a .308 case I noticed uneven seating forces. I was not annealing.
I was brushing the necks with a bore brush before and after sizing the case.
I decided only brush before sizing and leave a little bit of roughness and this let the bullets seat more even with a bit more force to seat them.
Just pay attention when seating bullets and go slow and steady when seating not jerking the press handle quickly in other words.
Not like anyone does that.
