I have a fair amount of reloading components sitting around. I've always been a fresh ammo guy, I like to load out what I need for that year but that's it. I've been wondering though, is it better to have larger amounts of loaded ammo for long term storage vs keeping everything in separate components? Short version, does ammo or reloading components store better? Considering it's all kept in a conditioned space, no sun light, etc...
I suspect either of the options you are presenting are better than the third option - keeping a mag's worth of rounds in the ashtray between seasons. That was Grandpa's standard operating procedure, and he never complained about misfires.
