I've heard that with a steady load of light and hot .357, after many founds (which is typical in competition), revolver frames stretch and there's nothing that can be done to save them. Is this typical with any revolver or with only certain ones from certain materials, certain brands, or certain calibers? More specifically, are there any revolvers that are basically indestructible no matter how much and what you shoot? For example, the Ruger GP100 or SP101? And how about the LCRs?
