Steve: I did just that many years back, when I was a bit faster and filled with myself. I found an honestly used Western Arms Long Range .410, opened the right brl to skeet and kept the left full, worked hard at low gun skeet using that gun exclusively, shooting 4-5 rounds per week until routinely hitting 22-23 targets, and did so for many months before the bird season. Used quality 3" 7 1/2 shells after quail behind pointing dogs with all the shots 20-25 yards. Did so for about 1/2 the season in KS and MO and gave up in disgust (at myself) for losing so many birds that had obviously been hit, despite some pretty good dogs. A sample size of one does not establish statistical significance, but that was my experience. Others have apparently had a very different result, which is fine and fun to talk about.
