So...I'm hankering for another 22LR rifle. I don't know why; I can't buy ammo for it. I think I want something super simple, super rugged, and super reliable. I envision a world, or a time, where magazines and springs are either unavailable or, due to personal economic hardship, unaffordable. I'm thinking about some kind of a bolt gun. I'm wondering about the validity of a single shot 22LR for grouse, rabbit, and squirrel. Adult sized single shot 22s are not common. Should I consider something with a box magazine and just buy 6-8 mags for it now, and use them up one at a time? Once the last one fails the gun is done. Next question is scope or iron sights? I've always preferred irons, but my eyes are pretty much at the point where I should be wearing prescription glasses for anything long distance.
