You know, I've always heard that you should pick a common caliber for the possibility of tight ammo supplies, especially in a post SHTF scenario. Most people argue that military calibers are great choices due to availability. As I was walking through the Sportsman's Warehouse today, I noticed a common theme with all the other stores in the area... odd calibers are readily available, while common ones are gone. Military calibers were the first to go. Want some .45? good luck. Literally, the ONLY caliber of handgun ammunition on the shelf was .41 Mag. in all flavors. I bought a Kimber in -06 just for the fact that as a rule, it's a common caliber. In Alaska, .30-06 is not that popular since many see it as inadequate for some of the larger game up here (I disagree). On the shelves, there were any flavor of .30-06 you could want, as well as .257 Roberts, .300 Savage, .220 Swift, etc. No .300 WM, .338 WM, .308, .223, etc to be found. Makes me wonder if the whole philosophy of common calibers for SHTF is flawed. In any scenario, people are going to hoard ammo for the caliber that they have, leaving only the oddballs available at the stores. (kinda like now) I'm really thinking about having my dad ship me up the old .41 Blackhawk, and looking for a really rare caliber high powered rifle.
