am I crazy for stocking up? I've spent over 2 thousand dollars in three months on ammo....I have 500 to 2000 rounds for every caliber I shoot...and I shoot a lot different calibers....
You need to think about the advantages of simplification.
Really, you only
need one caliber, .22 LR, for repetitive training and small game hunting, if it comes to that, two for defensive handguns (one, "mouse," for a vest-pocket/hide-out piece, one a "normal" caliber for CCW, etc.), one intermediate 5 to 6mm-ish (if not 7.62x39) for your CQB rifle/s, and something approaching 8mm for longer reach applications, including large game hunting, again, if the Piggly Wiggly has decided to close for good.
There
is an argument, like Avenger29 makes, for reducing your caliber footprint. Of course, my take with handguns has been to hold onto what I have, and find innovative ways to ensure that I could make use of cheap ammunition as I run into it -- extra barrels here, conversion kits there, revolver cylinder customizations elsewhere, so that I can double calibers up on single platforms wherever possible.
With rifles, it isn't always so easy, but I have a sufficient amount set aside so that I could get through a crink in the supply line for a while, and platforms that are fairly standard, with one glaring (but I ain't ditching it) exception.
