hey all need sum advise, what is the oldest powder you have used safely? with the powder shortage in effect options are limited so i aquired a few pounds of blu dot and 2400 from a friend (was his fathers that passed) at a very reasonable price apparently it was stored properly but is opened, from my research i dated back to around the early 70s?? sum are in cardboard containers and the 2400 is in a square tin, smells good looks good not clumpy should there be any concerns with it? i have loads of data for them in my books but im very new to reloading, i realize start low and work my loads up this will be for my 686 revolver in 38 spl and 357 mag loads, if there is concerns what would they be?
any input would be great thanks
