RE: 22LR or 22MAG
id say the choice is yours...like NT said, the rifle will matter more than anything. ive never had a problem knockin down bushy tails with me 22lr. accuracy is key....the nice thing is that even good rimfires are usually cheaper than a CF. i personally like my marlin m25...i dont know what they go for, but they arent real expensive...mine shoots really well
