So a good and cheap SHTF (in every way) rifle is the mosin nagant; it's powerful enough to take down anything, renowned for accuracy, and very cheap to buy and shoot. It's one of my first choices for a good gun as it's also indestructible. Next is a ak-47 for obvious SHTF reasons. some other good stuff to know if that property in oregon county is selling from 2,000$ to 15,000$ and a lot of it's 20+ miles from anywhere. Build a cabin, some solar panels, a food stock, munitions cash (including a ammo reloading kit), and you're set.
