I have small gauge side by sides in 26,27,28,30 and 32 inch barrels and use to shoot 25 inch barrels on SKB 280.I have found in dove hunting that i bump the 32 and 30 inch guns on the stakes that hold up the blind.I will take 25 and 26 every time for quail and grouse,woodcock hunting.27,28 ok .Might shoot better on doves,ducks with the longer barrels.Bobby
