You save about 6 or 8 ounces. It isn't worthwhile to do to save weight. Mine has an 18 inch barrel, I did it to save space. The box blinds over the food plots we hunt over in Alabama are all about 4ftX4ft. A long barrelled rifle is a nightmare to get turned around to a different opening off of the side, in case a deer does what deer do and comes in from a different way than you expected. I can lay the shorty across my lap and just poke it out in the direction I need to. Knock on wood, I've never banged against the side of the stand either. It points better than full length, handles easier in tight spots, and will fit in a shorter gun case, but the weight saving isn't there.
