So given your proposed scenario, How are you ensuring that if the stuff did hit the fan you are even positioned to survive? Many seem to focus on needing this that or the other flavor weapon. With out considering the basics.In a SHTF, the chance someone has a gun on them is pretty good. Most guns have decent accuracy at 100 yards. I am looking for a Caliber that gives me a little bit of an edge to move out of standard firing ranges while also being solid within that 100 yard range. I do agree though, 100 yards is a lot closer than most people think. When things start running, you are gonna want as much distance as you can get while also running a platform suitable to within 100 yard ranges.
