.22 - 1000
.410 - 250
12ga - 500 Buck
200 Bird
50 Slug
Guns-

NEF .308
AR-15
NEF .410
Rem. 870
i am in no way an expert on anything survial, but in regards to you shotgun ammo, 500rds of buck is awesome but i would think for getting food, bird shot would be worth as much if not more than .22? By your break down it looks like your planning an assault not a retreat
