well ok joe, lets just say we have a 12 bore gun that is 100 years old or so. would you agree that during that time, the stock wood could have dried somewhat and become weaken and brittle? plus, perhaps some oil leaked down into the stock head and soaked the wood, which also tends to weaken it?...then along comes some idiot who believes in the more is better theory of shooting...so he takes 1 1/2 ounce magnum loads and shoves them into our short chambered gun and heads off to his favorite goose field. has a wonderful time, burns up a few boxes of shells, bags a few birds, only to discover that when packing up, there is now a big crack in the stock of his old gun and the stock is now kinda loose...joe, i submit to you, that if the user of this once nice gun would have only shot the same pressure ammo that this gun was designed for, then perhaps it would not have cracked quite so soon and quite so severely?
