Stick with 556, 762(308), 9mm, 12ga as far as loaded commercial ammo for ban/ shtf scenario. Yes, my 6.5x55(s)can outshoot just about ant 308, however, 4 Nato calibers are listed above and likely can be sourced later... will my FiveSeven outshoot a 9mm glock - all day long- ammo availability for FiveSeven or PS90 in the “event”? Well, not easily.
Omitting 45acp, yes, due to magazine capacity limitations.
Favoring Glock? Yes. Simple, reliable and will shoot ANY ammo in any pressure load. Can I outshoot Glock with my HiPower? Every time. Is my Browning 200% dependable With ANY and ALL 9mm ammo - not exactly.
Plan and invest ahead, a lot easier to build up over time vs spending $25k or more all at once. When I quit smoking 8yrs ago, my wife deposited all money i would have spent/smoked weekly into my “gun account” plus a monthly bonus. So if you still smoking- switch your “investment direction”.
