I read “Patriots: A Novel Survival in the Coming Collapse”  a couple of weeks ago and enjoyed it. Thank you.
I wanted to mention: I try to follow conventional wisdom about caliber choices for SHTF  weapons. Interestingly, in the current ammo shortage, it’s still somewhat easy to get ammo for oddball calibers. For example, if one needs 7.5×55 Swiss, 7.65x54R Russian or 7.5×54 French, many online dealers have it in stock, while 9mm, 45 ACP , 12 gauge buckshot, 308, 223, 7.62×39 etc., are very hard to come by. For people who don’t have the budget to stockpile a lot of ammo, this may justify keeping at least one [rifle chambered in a] non-standard caliber in the arsenal. The bolt action Russian, Swiss and French rifles are relatively inexpensive, sturdy, and hard hitting. The fact that the ammo is in good supply during a nationwide ammo shortage is a bonus.
