(1) rifle
(2) two pistols
(3) 50 lbs of ammo
Macho, but impractical.
Your bug out bag is there in case you have to flee a plague (e.g. terrorists release Ebola into a nearby community), for example. In that case, you won’t be able to go anywhere *near* any other person, store, or house.
I’m all for packing adequate firearms and ammo, but lugging your proposed 50 pounds of ammo around when you are trying to avoid a flooding river or broken dam (most people have no idea how many dams are holding water back from their own homes mere miles away) is pretty crazy...especially if you end up having to swim for it.
Ditto for a wildfire headed toward your home, or a small/medium-sized meteor. The Russian Tungstra comet circa 1910 wiped out some 200 square miles. Modern sky-watching equipment and communications might...might...give you 4 hours of advance notice to evacuate if an unknown comet came at the Earth from the daylight side (most sky-watching views the night side).
Your bug out bag is there for an earthquake, or tornado, or hurricane. Katrina hits and you are stuck inside your house...your bug out bag gives you the option of evacuating if your Plan A suddenly collapses.
Riots in the street? Headed for your house? Your bug out bag gives you an option besides fighting everyone in sight.
Tsunami? Same thing.
Ethnic genocide ala Rwanda 1994 that wiped out more than 400,000 civilians? Your bug out bag gives you an option in addition to fighting against organized militias or living off UN handouts in some makeshift refugee camp.
Basically, your bug out bag is a “get out of Dodge” option.
50 pounds of ammo...if you’ve ever lugged such into combat...is the opposite of getting out of Dodge. That’s a “stay and fight” option.
Very different beast than a bug out bag.
