I have an old Winchester rifle that uses .22 Win Auto ammo. It ONLY shoots this ammo and it is the only gun that uses this ammo. There have been some major fluctuations in the price and availability of this stuff. Right after I got the gun I got a great deal on some of this ammo at $0.50/rd. I just happened to be looking around and found there was a recent limited run and bought a case (1000rds) at a price of $0.33/rd shipped. I have a total of 1400rds now and I don't plan on shooting this gun a ton, but I do plan on being alive and able to shoot for at least the next 40 years. This run was said to be 3 million rounds. While that sounds like a lot that is only 6000 bricks (500rd). Now there are only a couple of vendors that still have this stuff and the cheapest I can find now is $0.35/rd. I am considering buying another 1000rds. I guess if I don't shot it I can always sell it later. If there are more runs then I guess it could just be the price of being stocked up. Any thoughts?
