I need advice on which rimfire cartrige is best. I've been considering a Marlin 22LR, simply because ammo is cheap and plentiful, but I was reading through the Henry catalogue, and they had great things to say about .22mag and 17 HMR rifles. Supposedly, the extra velocity makes the guns more accurate. All I plan to do with this gun would be to kill paper targets and soup cans, so stopping power isn't important. What I really want is long-range accuracy. (No, my rifle skills are not "long range" but I'd like to start working on that). Which rimfire caliber would you guys reccomend for this?
