The newer 28 ga shotguns are pretty reliable, light weight, etc .... it's something I recommend for youth hunters.
My wife uses a youth 20 gauge. She has no problem getting her birds every year. That might be a good option for you.
When are you going? I will be out the 20th through the following weekend. If you are not going at the same time, tell Dave I have a 870 set up with a short barrel and sights you can borrow. It's killed a lot of Turkey's. I'm using the bow, but like to take it along in case I feel like taking a head shot.I also have a Franchi O/U with turkey chokes that is very light weight. Have him get in touch if you're interested. You are welcome to either.
