I currently hunt with a .30-.06 and have been thinking about a second rifle for the wife/back up. I believe the wife could handle the 06 but since she plans on hunting this year I need another rifle for her. I have a few different options already in my arsenal. I own an AR and a .243 as well as a 12 gauge. I've already decided to bring the AR up with me and am trying to decide if I should bring the .243 for her. It would save me some money b/c it is already set up and I already own it. What say you guys? Is a .243 ok for moose? I know shot placement matters and for what it is worth my wife was an expert marksman in the Marine Corps.
