"Brain picking"

I can not explain the whys of metal fatigue. I just know that it occurs in all metal. We have condemned bridges because of metal fatigue. Aircraft are prone to metal fatigue. I had a 1916 Erfurt in very nice shape. All matching. I decided to sell it and ran a few rounds to make sure it fired. Third round out split the matching firing pin. You can find many stories like this of parts falling apart. Maybe an engineer can explain the process. I'm just an old retired Forester. Bill
