Yeah I like the look of the Ruger, and a longer barrel would definitely be something I can appreciate. I'm probably going to end up using it if my girlfriend and I go small game hunting so that she could use my Remington 597.
And to answer that question, yeah, I already have 1000 or so rounds of .22LR. Oddly enough, around here in Northern IL, 12 gauge and .22LR are still in stock pretty much everywhere. I don't think there are that many gun enthusiasts around here, which is why I am pessimistic about looking used. I've browsed local gun shops and Armslist and haven't really came up with much so far.
