RE: pump action 22
pumps are OK.. but if you want a more accurate gun go for a bolt action. Plus since you mentioned that it was "in good condition", it sounds used. I wouldn't buy it unless I knew it shot good, which goes for all used firearms. There's usually a good reason someone sold it to begin with. Not too many people sell off rifles that shoot good. Not to mention that pumps have a tube magazine, AKA- pain in the butt to unload. Bolt actions usually have a clip. As for a semi-auto, I wouldn't use a semi-auto for anything but plinking cans.
