As I mentioned in my previous post, I've done the 12 gauge loads out of a 10 gauge experiments, and as a result I have completely shelved my 12 gauge guns for waterfowl. However, since I am nobody, and have never published those results, my findings are irrelevant, and are only for me to enjoy which I am more than ok with.
Like I also said, when using smaller shot (#6 and smaller), and lighter payloads (1 oz. and lighter) I've found the difference is negligible between 12, 16, and 20 gauge guns. If you want to shoot 1 oz loads of # 7 1/2 shot out of a 2" 12 gauge or a 16 gauge, you will find almost no difference in pattern uniformity. Although, I would agree the 2" 12 gauge is a much more interesting gun, that would command many hours of conversation over the life your ownership.
