I apologize if this topic has been had in these forums already. I'm realizing now how poor an idea it is to rely on 223/5.56, x39, 9mm, .45acp, etc. when SHTF. Seeing all that common ammo that's supposed to be 'widely available during SHTF' be wiped off the shelves suggests otherwise. Obviously the answer is to stock up, or reload (or both) and have yourself taken care of for a year or two..or more. Shooting happened on 12/9. Shelves began to empty the following Wednesday (19th). Shelves of ammo, magazines, ARs and the like pretty much gone nationwide in under a week's time. If there were an invasion or something serious other than just hasty panic and speculation, those shelves would have been gone in just a day or two I'm guessing. I've gone to two modest ammo manufacturers today (HSM and BVAC) nearby where I live and they were not only out of the popular calibers (223/5.56, x39, 9mm) but ordering 500 or 1000 rounds was at least a few months out for both...and that wasn't even a certainty. So either stock up when it's quiet...or pick a obscure caliber for your semi-auto centerfire rifle like the 300blk or 6.8 or 6.5 or 30ar. Thoughts? For my part, I've got a mere 500ish of x39, and <200 rounds of 5.56. Got caught with my pants down having blown through probably 2k rounds of 5.56 this year planning to buy a few k more with the tax return in February...not going to happen now.
