I mainly use my O/U for upland birds. My all purpose shotgun is a TriStar Viper G2 12 gauge with a 26" barrel. I got the 26" model because I felt a 28" was too long for tight turkey woods. My question is this, for upland birds and waterfowl does the 2" difference make much difference? Should I be looking at getting a 28" for the bird hunting? Any advice would be greatly appreciated, thanks!
