I like to consider what ammo will be most common when the SHTF.

Considering what rounds are likely to be plentiful, consider the government ammo buys of millions of .40 handgun. It has surpassed the 9mm as the choice of cops and JBT guns.

These days, I content myself with an all-purpose LR-308 for battle and long range use, a 870 of course, and my trust 1911.

Wife has a collectible .380 Colt Hammerless for laughs and beating on someone. But she can shoot well if she needs to.
