Buddy of mine keeps XX 1000’s in his store room.
Just large rifle and shotgun primers though.
I don’t need an ammo factory, I roll my own in the basement. I have enough brass to keep loading the rest of my life, powder isn’t a problem and bullets can be cast but primers are the issue.
Where is your primer store? can’t buy more than 1,000 at a time here, and most places are sold out.
