This is a working, up-to-date inventory of the ammunition I have in boxes. It's not quite complete -- I have a lot of stray batches of ammo of different calibers around, but this is 90% of it.
I also have any loaded mags of different calibers, all marked by type. I'll add that stuff in at some point, probably on a separate list.
I've covered a lot of the standard "survival" and self/home-defense calibers, but my main shortfall is too little .45ACP to feed my one 1911.
I have a bunch of .45LC to feed my Bond Arms Derringer. This is a bit of a specialty gun, but built like a tank and comes with interchangeable barrels in multiple calibers. So with this one gun and three swappable barrels, I can shoot .410, .45LC, .357, .38spl, and .22LR.
