I agree, in point. I have 5 older 12 gauge LC Smiths, fortunately, no cracks in the locks or tang areas- but I only shoot 1 ounce 1150 fps loads in them--except for the Ideal LONGRANGE and the Eagle Live Bird gun, both with 3" chambers and the under rib reinforcing yoke-- in those 2 heavier 12's I will use 2&3/4" AA Handicap Trap loads at 1250 fps. and 1& 1/8 ounce shot loads--as well as the 1 ounce loads when I am shooting barn pigeons and pest birds for practice. . I can't state this as gospel truth, but I believe one reason these Smiths have remained intact and stock cracking free (their Achilles heel) is from my religious usage of only lighter loads. My 2 cents worth--
