First my comment was directed at Ford8nr. He was doubting my localized findings. Not sure why you would take umbrage at that. 2nd of all, I do not in any way believe there are conspiratorial powers at work. Simply a normal thing to do. If you can sell all you make as close as possible why use expenses to deliver further out?
I made that comment because your assertion is both invalid and unsupported.
CCI, for example, is located in Lewiston, Idaho which is arguably significantly closer to Washington state than the East Coast.
Remington's ammunition plant is located in Lonoke, Arkansas, which I'd say is fairly central with respect to relative distances from the two coasts.
Federal's plant in Anoka, Minnesota is, likewise, pretty much central between the two coasts.
Winchester's primary facility is located in East Alton, Illinois which, again, is pretty much central.
Walmart, being the store in question here, is about as good as it gets with respect to coast-to-coast operations and they keep their various stores in business by keeping them stocked. Which means they make shipments to their stores all the time for EVERYTHING they carry...and shipping ammunition along with those other items doesn't cost them squat in terms of dollars per volume/weight in comparison to all the other stuff they ship.
So your argument about supply lines doesn't really hold water on an economic basis. So if this is, in fact, happening, then it must be for some nefarious means, hence the conspiracy thing.
If you could cite some kind of credible source that says that all the U.S. manufacturers of .22 LR then please do so.
Now, please don't think I'm doubting the availability of ammunition in the stores you're talking about. After all, you are the one living there, not me. Whenever I go back to Puget Sound Naval Shipyard on another engineering support job, I'll be happy to visit the various Walmarts to see for myself. Of course, by then the market may have shifted significantly and will make my observations invalid with respect to our current conversation.
I, too, have difficulty finding .22 LR ammo in the various Walmarts on the East Coast, between Virginina (where I work) and South Carolina (where I live). However, my hunting/buying strategies are apparently different from a lot of other people's.
First of all, I have plenty on hand to supply all my families shooting needs as a buffer. Which means I can afford to simply look for .22 whenever I happen to be out and about for other things...and when I do find it, I buy in order to help replenish/maintain/increase my current reserves. I don't allow my stores to be depleted to the point where I MUST find some NOW if we want to go shooting/hunting.
This is what I recommend to anybody else...buy sufficient ammo over time to create a reserve that will support whatever amount of shooting they wish such that they have the time to casually look for and buy whatever they find incidentally to their other shopping activities.
Oh, and by the way...I built a lot of that reserve up AFTER the current ammo debacle started. I currently have about 6,000 to 8,000 rounds of LR and about 4,000 rounds of WMR. The WMR was the result of casually building up my reserves over a period of a few years while I was still active duty and my deployment schedule/family time didn't allow me much time for shooting. The LR amounts were post-2012 purchases.
