Can you fire over-annealed brass to hard it up? Save it?

I'm not sure how you define "over annealed", if the brass is burnt,toss it in the scrap, no point in risking your safety for a couple of dollars.

I have annealed brass to reform 7.62 to .243, and also other cals to prolong case life. Only use a propane torch, a catch can of water and eyeball.

I never had a case with a loose neck, only let the heat line run to just below the shoulder,and drop them into the water.

Be Safe.
