In the event of SHTF, what theory are you operating under?    Do you think NATO countries are going to helicopter-drop ammunition on camps of white nationalists? I hate to tell you this, we won't be considered allies. At best, we will be considered potentially useful but expendable cannon fodder. You don't want that supply-dropped ammo if its price must be paid in your blood, and that of your group. Make no mistake, they would HAPPILY spend the lives of WN's in suicide attacks in order to eliminate us from any future society.    What's the other scenario? I'll be able to buy these NATO calibers in the store because the manufacturers make more? I hope that folks paid attention to gun store shelves during the run on ammo when Obama was elected. Sticking to the standard rounds is the same damned philospophy 90% of the REST of gun owners are following! In emergencies, the shelves are going to be bare of all the standard rounds and calibers. But I've seen a fair amount of .270 and .243 on the shelves, because maybe 2% of the gun owners need it.    I am far from advocating that people standardize on weird hunting calibers, but I do believe everyone should have a few off calibers. Way down the line, the only calibers available will be the weird ones.    The winning solution... make sure you have enough ammunition for  yourself  and any others you may bring into your group post-SHTF. If you figure on taking 4-5 into your house post-SHTF, make sure you have enough ammunition to train them, and enough for them to shoot. 10k ammunition  per soldier position  in any given caliber should be enough. Note that I say position, not soldier... liberals, even if they're awakening are expendable compared to educated and prepared WN's. Your job is to train soldiers and manage the group, not to be on the front lines.    Next up, you shouldn't waste your ammunition on unarmed opponents. If they see your group is armed, chances are that unarmed opponents aren't going to attack. So... if most of the folks you spend ammunition on HAVE ammunition and a gun to use it with, then chances are you will operate under a 'net profit' for ammunition.    So, final analysis: figure out how many people you intend to have in your group, and YOU SECURE 10k rounds per person. Don't tell people bring your ammo and meet up at my farm, their wives will make them leave it behind for more water and diapers, etc etc. Or let folks buy in SHTF slots at your place; they buy 10k rounds and it gets stored, untouched, in your basement. Whatever... just make sure there's 10k rounds person.    And, pick up a bunch of rifles in a variety of calibers. Hakims for 8mm Mauser, AR-10's for 308 (different uppers on those should let you shoot a few other calibers... I think 270 and 243, if not both), 50 BMG, etc. Revolver rounds seem to do fairly well at staying available too; 357/38 and 44 weren't even close to as scarce as 9mm and 45ACP. Of semi-auto handgun rounds, 40S&W actually stayed fairly available for a while, compared with those too.    As for 9mm, forget it. Everyone and their brother has at least one 9mm gun and tries to stock up on it during the slightest hint of an emergency.
