The 20-gauge Boss Round Action SxS carries all the features of the 12-bore version in a lighter, more compact package. At under 6 pounds, this is one of the best-handling driven-game guns ever produced and is particularly favored on driven grouse where crossing shots require a fast, responsive gun that does not tire the shooter over a long day.
