I recently purchased a Ruger 22/45 with the idea of saving some money at the range by using .22LR ammo. Of course, now .22LR is almost impossible to find.
Almost, but not quite. Lucky Gunner had something like 195 boxes in stock as of yesterday, so I ordered a few. This morning, they're all gone. If you buy ammo online, you've just got to keep constantly checking.
Incidentally, I highly recommend Lucky Gunner. They don't backorder; if it's on the web site, they've not only got it in stock, they tell you exactly how much they have on hand. I've ordered from them several times, and the service is excellent.
