Now I do appreciate this post as it gives alternatives other than just "should have been prepared".Sure you can. The ammo is out there, it's just going to cost more. Even at inflated prices though, .22lr is STILL cheap. In the last six months I've not paid way more than normal retail price for .22lr, nor did I wait in line at crapmart. I've bought 12k rounds over that time to start replacing my stores which took a hit in a year and a half of not buying. That aside, there are alternatives. Really good air rifles pack as much wallop as a .22lr and cost way, way less to shoot and you can make your own pellets. Muzzleloaders are also cheap to shoot and ditto re: making your own bullets.
It may be fun to burn up ammo like the zombie hoard is upon you, but if you can't afford 1500 rounds at today's prices, consider investing in a single shot rifle and slowing down and having family concentrate on shooting very accurately. Once you get into it, precision shooting is way, way more enjoyable over a longer time than blasting through because there is a whole lot more skill involved. I average 10-20 rounds a day of all the calibers I shoot (pistol and rifle), almost every day and get several months of enjoyment out of what some people blast through in a weekend.
Point in fact, from March 2013 until April of this year I was not employed and other than the fact I didn't buy new toys or much of anything not immediately necessary, I was able to lead an otherwise normal life, including shooting daily, because I had that tanker load of gasoline stored, some money in the bank, food in the pantry, and enough ammo for me to shoot at my normal rate for several years. Further point in fact, I've done all of that in spite of the fact that I have never made above the poverty line.
Meanwhile, I am going to continue to beat the drum of being prepared for shortages and sometimes that's going to involve rubbing people's face in their lack of preparations in the hope that the NEXT time this rolls around they won't be one of the complainers. You have a choice for next time, which will you choose?
I have explored other options I have available. .40 7.62x54 and 12ga are other cailber s I have tried out. But unfortunately every body loves the .22.
I currently am looking into a .17 hmr to help slow down ammo consumption.
