A Savage Axis in 223 would be a very accurate rifle and one of the less expensive choices as some of them even come with an inexpensive scope as a combo deal. Since you're not planning on using it very often, you wouldn't have a huge amount of money tied up in a rifle/scope combo that sits in the safe a lot. And if you get hooked on the sport, it's still a very accurate and lethal rifle & caliber that's almost tailor made for yote hunting and has fairly inexpensive ammunition if you don't reload.
