I am a big fan of the .17 HMR! I have had a Savage 93R 17 bolt action for about 5 years. It is without a doubt the most accurate rimfire that I own! I currently don't have a .22 mag in a rifle. I do have Super Single Six in .22 mag. The .17 HMR can do most anything a .22 mag but...is MUCH more accurate at 100+ yds. For example last year I shot a fairly large groundhog (17 lbs) at a measured 117 yards. One shot DRT! I would not have tried that with a .22 mag rifle. I had a Marlin that was fairly accurate for 50-75 yds but not much further. The .17 turns the insides of a groundhog into jelly when they are hit. The .22 tends to just make holes through them. The .22 mag is fine round for closer in pest control. BTW, even throughout the ammunition buying frenzy I have had no trouble finding .17 HMR. .22 mag is very scarce around here. Good luck!
