Alberta is waaay too varied in both species and climate to "ONLY" have two guns!!
At least this is the story I have been telling my sweet bride for all of 37 years now!
Nothing in this province that a 30-06 can't handle. Load heavy for caliber bullets and you're golden. If you want something a bit bigger for fear of moose, elk, or the bruins, I would say go with the .338 or , the almighty hammer of Thor (
, the .358 norma!
The short iron-sighted lever guns are great in the bush, but I would not risk the success of a prairie hunt on them.
