I haven't measured the forcing cone area of my 30" 0 frame 16 hammer gun, but the stock book lists it at 7 pounds 3 ounces. I can't remember the marked barrel weight but I doubt that I'll ever blow her up. Marked barrel weight of two other 0 frame 16 hammer guns is 3-10 and 3-4. That 28" Laminated set at 3-10 is a real horse.
