Hi guys , newbie here. I recently purchased a reloading lot off a guy and it came with a bunch of 45acp brass with the head stamp of F A and the number 42 on it. Im assuming that these are WWII? Here is the thing though they are already primed with what looks like original primers. They appear to be the corrosive kind and wondering if it would be safe to reload them? I know there would be alot of cleaning after shooting these. Im planning on putting one in my 1911 (not loaded) to see if the primers will still go off. Any suggestions/advice is appriciated in advance. Also they are non magnetic but dont look like brass?
Thanks
