I've done some deeper research and now stand corrected. I believe the velocity they published was for pistols, not rifles. However, I've not found any place that has published 2200fps for 30 grain. If that is the case, then this is a hotter round than I thought.
On the other hand, all the data I've found shows the .17 HMR to have a much flatter trajectory, droppinng 2.6 inches at 150 yards, while the .22 Mag drops 4.5 inches. I don't even try to shoot small game at 200 yards with a .22 Mag, but routinely dispatch them with the .17. Of course, I don't think I'd try to even shoot a fox that far out. 150 would be the furthest I'd try on a fox. The bottom line for me is that I can hit what I'm shooting at much more consistently with the .17, and place the shot exactly where I want it.
I still like the .22 Mag. I've got a Ruger Single Six that is a ball to shoot in 22 Mag.
