Nothing really. Which is a great place to be I suppose. I guess if I had to come up with a short list.
1) My (departed) dad's Citori in 20g (my nephew has it and I'm good with that).
2) An AR styled .22 (may build one).
3) A take down 10/22. I have absolutely zero idea why I want one of those, and have zero need/use for one, but you know.....
4) Browning Gold Cup - Goes back to being a kid and seeing my oldest brother take one brand new out of the box and send a clover leaf down range in his first three shots at 25yds. (Not that I could ever do that but it's besides the point.)
I like the take down as well even though I have zero need for such a thing. For an AR-22, the S&W is hard to beat. They go on sale for $299 sometimes and they are good guns with good factory mags, especially for the price.
