It is used for about the same things you would use a .22 mag for.
Guess this sentence stuck in my head for some reason, sorry Paul. My only point is that from my personal experiencea 22. mag does not have what it takes to group well at 200 yards where a .17 will. Ihave two rimfires setup exactly the same except one is a.22 mag, the other a .17 HMR, the .17groups better especially atlonger ranges. Paul do you feel that I am way off base with this? The guys shooting those accurate .22 mags you refer to are not shooting at 200 yards. But this is my personal experience, I would think it would go without sayingyour experience may vary.
