I used to have a Browning Citori that was chambered for 3-1/2" shells. Whenever the shooting position was odd or directly overhead, the recoil from the 3-1/2" shells reminded me to better choose my shots.
Also, be sure to check the conditions you're going to be hunting in. Over-unders don't load and reload very well in tight quarters, like duck blinds and boats. I found it akward, so I went back to a semi-auto.
