When I go to a WallyWorld or an LGS, I try and get as much 22 RF ammo as I can. I shoot some of it, sure, but I also have a little bit saved back for a rainy day.This last frenzy even convinced my wife that I am not completely crazy for having my ammo "stash".
She doesn't shoot anywhere near as much as I do, but in seeing all the empty shelves every time we went by Wally World she finally came around to realize that the time to buy is when it is on the shelves. The time to buy extra is when ammo is plentiful and available.
