About 5 years ago I went on a non stop reloading binge and reloaded about 12,000 rounds of varios handgun and rifle rounds I went so far as sealing the primers it must have burnt me out cause I have not reloaded in a few years since ,what do you think the shelf life is ? should I get started again reloading after shooting the old stock or can I depend on them for years to come. I have ww2 45s that still fire but lack power when does that start to happen//jim
