i find the story by fclassguy very interesting. over the years i have seen many guns come into my friends gunsmith shop that had suffered a ruptured case most of these were from firing the wrong cartridge for the gun. actions ranged from remington 700s, 788s, rugers, parker hale commercial 98, p14 enfield, voere 3 lug action and others i can't remember. some of the actions suffered serious damage but amazingly i never heard of anyone being injured from these mishaps.
