I love the 17HMR (I have a few of them including the new marlin XT-17VSFL) but if I am going to be 100% honest I think the 22mag is a better hunting round.
Shot placement is everything! I would rather take a round of 50BMG to the foot than a 22short to the base of the skull.
all 26 of my guns are 45/70 govt, 357 mag, 22 or 12 ga... I believe in keeping it simple. Wish my wife did as well...
