This may sound stupid, and probably is, but the last time I went I used a .17 pellet rifle, which was last year and with the cost of .22s and being hard to find, I did the break action deal, It worked for me however I did miss a few, it's 2 moa at best for me, but I still have a lot to learn on properly hunting with a air rifle.... But if you plan on a jump shot on a rabbit, unless you have a shooting show on tv, I'd take a 20ga.
