I am looking to buy a new shotgun, and am thinking about the Remington 1100 G3. This can handle both 2 3/4" shells and 3" shells. I am leaning towards a 20 gauge, as most of my shotgun needs will be handled well with this, such as quail/dove/skeet. However, I would also like to be able to use this as a turkey gun, and all my limited turkey experience is with a 12 gauge. How do 3" 20 gauge turkey loads compare to 2 3/4" 12 gauge turkey loads? If they perform similarly, I would favor going with the 20 gauge.
