Ditto, running out of ammo to buy blew chunks. I can understand the idea of limited stores but frankly there are millions of rounds stockpiled. I forget how many billion rounds of 7.62x39 ammo was left in just the Romanian AK plants at the end of the cold war but it was oodles and more oodles. The amount of which has made its way stateside? Well, it might not be easy to get at...in a world gone to shit, most of the population dead, ammo scarcity would only be an issue if you really lit some bastards up. Stuff like 5.56x45, .270, 7.62x51 pr x39, 9mm, etc wouldn't exactly vanish overnight. It might be hoarded but it would hardly dry up entirely. Stuff like my 6.8 or a friend's 5.7mm wouldn't exactly be there for mass consumption.
If you're not moving you should be shooting, if you're not shooting you should be reloading, if you're not moving, shooting, or reloading someone is going to cut off your head and put it on a stick-Clint Smith Thunder Ranch
