At a rough count, I have firearms in roughly 53 different chamberings on hand.
Ammo stocks range from "0" for .32 Rimfire Long and .41 Swiss Rimfire to "Shiva Only Knows How Many Thousand" for .22LR. Most of my "working" calibers (.32ACP, 9x19, .38Spl, .44Spl, .45ACP, 5.56x45) have a couple thousand rounds in stock at any time. I get antsy if there are less than 2k rounds of deuce-deuce in the ammo can.
This is not counting my roommate's stocks.
You do not need to worry about any of this stuff getting released onto the market and depressing prices. That would be like trying to resell cans of Campbell's tomato soup.
