When I used to reload for Li'l SUZI (and other unnamed weapons), I'd keep about 20K of 9mm, 3K of 45ACP., 2K .38Spec., 1k .357Mag., 2K .223Rem., and another 2K assorted. I also had at least 10K primers and 10Lbs. of powder. I also have a 30Gal. parts washer filled with NAPTHA in the gun room. Never had any problems in 20 years of having all that so I doubt your packaged up ammo would ever be a big problem. Karl.
