I'm planning on buying a new shotgun to use for turkey and duck hunting. I turkey hunt a lot more than duck hunt so I would say it would be used 80% for turkey hunting and 20% for duck hunting. My question is can I get away with buying a "turkey hunting" shotgun with a 24" barrel and change chokes when I duck hunt or would I be better off buying a shotgun with a 26" barrel? I have heard people say that longer barrels are better forduck hunting. I'm not planning on going with a 28" barrel (just to let you know). Is there that much difference in 2" in barrel length?
