ChopperLump a couple of years behind you, but my mobility went south at 70 too. Have found that I can still kill ducks at 40 yds. over decoys with the proper loads in a 20 or a 2 3/4 12. Easier to tote, more responsive and a joy to hunt with. I worked the famous Horicon Goose Marsh during the lead shot era and the steel shot. The newere non toxic loads were not available yet when I retired in 88. The majority of shooters at Canada geese could not tell the difference between 100+ yds and 50 yds. Goose hunters killed their bird consistinly with lead or steel as they could judge distance.
