In looking at what I have in my ammo locker I think I am SHTF OK. But that isn't why I have all of it. I just buy what I find cheap for what I shoot!
Non milsurp, not a lot except rimfire, probably 3000 rnds of 17HMR 22 Longrifle, and 22 Mag combined. 1 box 25ACP, 2 Boxes 32 ACP 100 rnds Misc. 380, 400 rnds 9X18, 1000 rnds 9X19. 700 rnds 38 spcl, 100 rnds 357 Mag 100 rnds 40 S&W 100 rds 10MM, 300 rnds 45 acp, a partial box of 44 Mag. And a few 7MM rem Mag for my deer rifle.
Surplus, and milsurp ammo. 1800 rnds of 7.62X25 cause it's cheap and I love shooting my toks and CZ52. A couple boxes of 7.62 Nagant and 32 Long for my 1895 Nagant. 3000 rnds 7.62X39. 5 SKSs and an AK to feed!. 3000rnds of 7.62X51. My L1A1 FAL could be handy in a SHTF situation. 1800 rnds of 7.62X54R. Ditto on my Dragonov plus a few Mosin-Nagants. 1000 rnds of surplus 303 British. Hey, they served the Brits well! 1500 rnds 0f 8X57. Several Mausers, and a Hakim that is hungry. Probably more I have forgotten.
All of this has been accumulated over the past few years as it became available at a good price just for fun at the range when I could get away and go shooting. I haven't been able to do a lot of shooting until a recently. I'll restock as prices permit.
No tinfoil hats, just like to shoot!!!
