G'day,

This question is open to all. Does unfired brass have a shelf life? I have several lots of brass that would be well over 10 years old and never fired. Would this brass harden with age compared to newly manufactured cases? Would it need annealing due to sitting on the shelf for so long? I tend to buy bags of brass in the not so popular chamberings when I see them and store them until needed.

Also, I have 100 .250 Savage cases that were fired once and stored for about 10 years. I noticed the other day that quite a few have split in the neck. Does the once firing process affect the shelf storage life? If going to store fired brass for a long period would it be beneficial to anneal it before storing it?

Thanks for your thoughts.
