Love me some 22 because they are a ton of fun. The coolest thing about 22 is that new shooters, recent converts, kids, small people, just about everyone can shoot them and will enjoy shooting them.
I have a 15-22 and it is awesome. Make sure you have High Velocity ammo for it. I like CCI mini mags and Federal Auto match the best. But my favorite 22 by far is the Henry Golden Boy. Four Seasons seems to always have them at a decent price. I like it the best because it eats any ammo available. It is not finicky at all like most 22's are. You can shoot quiets, shorts, crappy thunderbolts,whatever.
I can shoot it indoors or outdoors and it is plenty accurate out to 150-200 yards. CCI quiets are very quiet and can be safely shot places others can not, without drawing attention.
The capacity is a plus as well, holding 15 rounds of 22 long and 22 rounds of 22 short
And they are beautiful.
