With the addition of Ballistic tip ammo, I would lean towards the .22 Mag as I feel it has made the round much more accurate than years ago. Tube feeds are available and I feel the round will take care of what your intending to shoot up to 125yds. On a slightly windy day the .17HMR will move around quite a bit, probably not enough to cause you to miss a critter although why take a chance, they're a pretty light bullet.
