I'm putting together a 280ai and a 30 Gibbs and I ended up with 200 new Norma 280 Remington brass to use for each of these. It seems like quite a bit of case working on the Gibbs case before I actually get to load and shoot a round. I'm going to be C.O.W. fireforming to not waste bullets. Should I anneal this new brass before I do the fireform? I think the expanding to 30, then to 338, then sizing back down to 30 will harden the brass some and perhaps it would be good to anneal it before fireforming to avoid the case stretching in the lower regions? What do you all think?
