I'm looking to buy a shotgun. Ive been borrowing friends shotguns for the past couple of years and its definitely time for me to get my own. The bulk of my hunting is dove and quail so im looking for a good field gun, probably a 20 ga or 20/28 ga combo. Ive been shooting side by sides and over and unders for the most parts, and would really like to get either one but not sure if my budget will allow this. All the suggestions my friends have given me are alot more than i am able to spend right now. Im hoping to spend no more than $600. Any suggestions?
