SHTF means so many things to so many people. To me, it means 2 things:
1. Defending your homestead for an extended period of time against those who will "Have Not" when and if the bottom falls out of our world as we know it. For this reason, I always have an ample supply of 5.56, .308, 45ACP, and 12 GA. Way to much to carry if the next situation occurs.
2. Getting out of town through the "adverse conditions" that are trying to keep you contained, and then foraging for survival. In this scenario, I'd probably grab one ammo can of 840 rounds of XM193, (in addition ot the 180 rounds on my vest), one ammo can of .308, one ammo can of .45, a case of 12 GA. (Mostly Game Loads), and a few thousand rounds of 22LR.
The probability of either if these 2 happening in my life time (I'll be dead by 2030) I think are less than .1%. So, how do we justify our "Stashes" ???....We don't need to because we are FREE!!!!!!
Just my .02 cents worth.
