Well, depending on who you talk to...yes, Ontario has run out of groundhogs. Truth is, they're still out there...but talk to any old-timer here and their numbers are a mere fraction of what they once were. Opinions vary as to why, I suspect it's a combination of factors. Anyhow, we've all heard the stories of .22lr dropping moose and I have NO doubt a well-placed shot with one on a groundhog would rapidly do the same thing...BUT, I think there are better tools for the job. I've been at it several years now, starting with a .17HMR
Did the job, but only head shots would reliably drop them in their tracks and even some of those seemed to need a second shot. I then bought a .22WMR and honestly, it took them with more authority.
Then, as the season wore on...it became difficult to get within rimfire range of any groundhog~they'd bolt the moment they see you~which I assure you, can be more than 150 yards away. Allot more. Might speak to the amount of hunting pressure..the time of the year they have their young...but centerfire is the answer for that kind of reach. Good shot placement with a .223 and a good scope really makes for a forgiving groundhog rig, and it really anchors them. That is, the ones that don't go airborne.
Yes...I felt like talking groundhogs and showing some photos, but I get your point buffdog. I'm not a "bigger is better" kind of guy with anything, let alone, rifles but I DO have countless hours under my belt chasing groundhogs around. It's the way I've spent every free moment for the last 4 summers. I'm still learning of course and YES, I will have the 17M2 out to try on them next spring. I don't have a pile of faith in it for shots outside of about 50 yards (on groundhog-sized game).... you see the size of the ones in the photos. They're tough animals, and get pretty big. One thing I can't stand is seeing an animal suffer so whatever minimizes that possibility, I'm keen on doing. I'm not looking to change anyone's opinion on the matter, dead is dead where varmints are concerned.

I will, however, keep an open mind with this new (to me) round and take into consideration everything that's been said about it. Easily 1/2 the reason I got it is to get it out west somehow...and see what this gopher scene is all about. Average groundhog day is 4-6 groundhogs seen...2-3 shot. From what I hear, most gopher hunters wouldn't even bother going out unless the numbers were about 10x that!
