There's a lot of larger / older bucks in KY now the way it is. The problem is people don't really know how to find them, but they are there. I actually see more big bucks in December than I do in November.
I don't think changing the gun season will make a difference.
Bought a Stoeger 12ga semi auto last year. Love it. I've been duck hunting for years with a Remington 870 12ga pump and wanted a semi auto with a longer barrel. My youngest son has used a stoeger for years, he likes them also. great guns in my opinion.
