I have owned several 12 and 10 gauge shotguns over the years. The last 10yrs or so I have shot a Benellie 12ga SBE. The 10's put a lot of shot in the air - they are also very heavy and slow to swing. The SBE is perfect - it swings quick. We do most of our duck hunting over decoys - the 2.75 work good here. We field shoot canadians over decoys - 2.75 or 3" work well here. We also go out to South Dakota every year to shoot white geese. We have an area that we have a lot if success pass shooting them - fr this we step up to the 3.5" shells. I do much better with the 12 shooting geese than I ever did with the 10's. I have never felt undergunned with the 12.
