My grandson checked the local Walmart last night, all they have in stock is some 30/06 and 12 gauge.
One of our local Three Bears stores which is like a smaller Costco here in Alaska has a full inventory of rifles and pistols, full ammo shelves as well.
But they also have signs saying they are out of the poodle shooter rounds like the .223. Most people carry at laest a .45 in AK because even the 9mm and .40 is insufficient against bear, the 10mm is the minimum.
So we have plenty of 10mm, .41magnum, 44magnum, .500 and such big pistol calibers.
What we don’t have is .22lr of which many Alaskans don’t have much use for though many have .22lr pistols and rifles. Its just a target range caliber and occasional small game round.
The .223 is pretty much a joke but can be used for wof control if its the right ammo but its not good for anything else. The .308 is also out of stock and actually its used a lot but not for big game, its a useful cartridge for hunting and is or was cheap.
Alaskans do NOT shoot off thousands of rounds willy nilly on the weekends, there is some indoor pistol ranges but they usually do not like the big magnum stuff, there are some outdoor ranges but with the adverse winter conditions they are deserted half the year.
So in summary Alaskans naturally stockpile ammo, what is off the shelf is the common NATO stuff and light pistol rounds. Almost all popular big game rounds are in full stock plus the lighter fast stuff like the 22-250, .243, 270 and such.
The DHS may have a billion .40 cal hollowpoints but 150 million people are stocked up with 30-06 and larger calibers hunting rifles.
And about those MRAPS, oooooh so scary...I bet they don’t float very well, cannot handle -40 temps, cannot be driven in deep snow or tundra and will probably breakdown and will have to wait for months for the most basic of repairs.
