Because LC Smith are normally lighter than the average when it comes to doubles. Physics. Id love to know how much it weighs, likely less than a Fox or Parker or other era double gun. To each his own.
I have a Fausti 28-gauge SxS that weighs 5 pounds 2 ounces, and have used it quite a bit with Winchester's 1-ounce load loads without experiencing any pain. The pretty much maximum shot charge for 2-3/4 inch 20-gauge bismuth ammo is an ounce. Kent's load is rated at 1200 fps, and Winchester's 1-ounce 28-gauge load 1205.
