Right now, the only .22 mag I'd like to find is Hornady CD for my little NAA Black Widow. I haven't been by Academy in a while. Even a standard Walmart is 20 miles from me, a super walmart 40, and anything else is 60 or more. The flip side of my location is that I can shoot wild hogs right off my back porch.
But, Academy used to have the Hornady stuff and I'll get by an Academy eventually. If the .22 mag is coming back, maybe it'll be there. I've checked the LGSs around me and no dice, though I can get CCI for my rifle. Plinking with .223 is just as cheap and more fun, though.
Another bonus to ..223 is I can reload it if it ever gets in short supply again.
I shot a squirrel once 5 years ago with the .22 mag. That rifle, a Remington 597 Magnum, is 1.5 MOA accurate out to 100 yards. I shot that turkey with the gun. That's all I've ever used it on other than targets. It's a cool gun to shoot, though. I traded a guy a small motorcycle for it that I didn't want around anymore. I got the better of the deal.
I don't think I'd ever bought a .22 mag. Not much I would use it for that .22LR isn't more suited for and now that I have a .223, well, but I don't sell accurate rifles.
I don't mind owning this little rifle, it's just a cool gun. The trigger was terrible, but Volquartsen fixed that. Now, it's delicious.
