Since we have to have a combo license now to hunt deer, I thought before the muzzleloader started I would try some upland game. I've never done it before. I have a 20 gauge with a 2 3/4 chamber. I'll be on the Blue Mountains near Blanding. What could I expect to find there? What habitat should I be looking for? What size shot should I use? Do I need a shotgun plug? Thanks for any help.
