Being new to turkey hunting, I ask your advice on the following. I have two shotgun options to choose from. Both shotguns are 12 ga., the first is a pump action 28 in. barrel w/ modified choke and a 3 in. chamber. The second is a semi-auto 30 in. barrel w/ full choke and a 2 3/4 in. chamber. In your opinion(s), which would offer me the better choice. Both shotguns are fixed choke.

the full choke for turkey, if you want to hunt any other wildfowl you will want a shotgun with interchangable chokes. 2 3/4" will work fine for turkey
