overhunting, a boom in the coyote population several years back took care of a lot of them as well, which in turn were taken out by an outbreak of the mange. there was a time when your groundhog kills were limited only by how much ammo you brought with you - now youre lucky to use up a single box of ammo. there is a LOT of walking involved. i covered over 35 miles of farmland the last time i went out - on foot, carrying a 15lb gun, a canteen, 60 rds of .223 and some sandwiches. there is no way i will take a heavy barreled gun again. altogether i got 26 hogs that day.
the best area in Ontario for groundhogs is around Durham. unfortunately there are a
lot of city idiots moving into the area and getting permission to hunt on land is often difficult -- they move there from Toronto and build their dream house on some cheap farmland, and think that groundhogs are cute fluffy little animals - they even feed the f**kers.
a lot of the farmers that do live around there and realise that they are pests buzz around their own property and the property of all the other farmers they know on ATVs and shoot most of the groundhogs on the first nice day way early in the season - which usually falls on a weekday and comes out of nowhere so you have no hopes of getting out there.
there still are some hogs but you need to drive around the old dirt farm roads and
really get into the remote fields. around the towns youll see them right along at the side of the highway, or out on the grass in front of the restaurant you are eating at, but you cant shoot them
i take back my Tikka suggestion. the Tikka i owned, i purchased used so i never really experienced buying rings for them. i just priced optilock bases and rings for a Tikka and it came out to over $160. knowing that, i would look into a better rifle like a Ruger, in addition to the Savage. very Mauser influenced design with controlled round feed, huge claw extractor. nice laminate stocks,
great fit and finish, and they include a set of good quality rings that fit into bases right on the rifle, so you actually save quite a bit of money (and a touch of weight) that way.
look into the Ruger M77 Hawkeyes, or even the Ruger #1 single shot rifles. try to find a medium weight barrel, but youd be fine even with a sporter weight unless you intend to be taking more than a couple of shots per minute, which is unlikely in most of Canada.
