Barrel length is all about balance & weight. Length is more important in wingshoothg than turkey hunting. Back in the old days longer barrels did hit harder & farther, but that was because the powder needed a longer barrel to burn up completely.

With more modern propellants mostof it is burned upbetween 22"-26". That beingsaid, I've done most of my shotgunning with a 28" barrel, very versatile. My only complaint is that it doesn't fit into my hard case w/o being broken down. A 26" barrel would fit better. I also have a turkey gun with a 21" barrel. It's fine for turks, but not such a goodwingshooting gun-too light in the front for me to swing accurately.
