Guns
primers
cases
lead
jacketed bullets
powder
of course the appropriate presses, dies and molds and other accoutrements
surplus ammo(and some other store bought ammo) is also in my stockpile...
Got a recipe for that?
After using the .22 rimfire for pot meat the corbin press makes good use of the cases for making .224 jackets for swaging EBR recipe bullets at home.......:o)
I really like mine.
Also good storage for primers and powder is to get a chest type freezer (that is not plugged in)..... I use a food saver system to vacuum wrap the bulk boxes of primers and assorted cans of powder, place em in 20mm or 10 inch fuse surplus ammo cans then place into the old chest type freeze. Put the date on each package and can and it should last a loooooong time !
Also consider MANY spare sets of dies for your common use calibers. As well as key spares for your presses etc ...
Think analog versus digital on precision measurement tools. I even keep a few slide rules laying around in the tool box......:o)
Just what I do to provide for an ample ammunition supply should the store be closed.
Stay safe !
