An employee had a rifle bolt severely damaged while firing factory ammunition. He couldn't attribute the damage to anything other than the factory cartridge. He called the ammunition company and they refused any liability. He contacted the company that made the rifle, and to his surprise, they replaced the rifle. I have had many misfires with cheap .22 LR and cheap shotgun shells and once had a .308 round that when fired, displayed excessive noise, recoil, the case was hard to extract and where the bullet impacted is a mystery. I won't mention brands because I have no hardcore evidence of what is to blame and have no desire to bash anyone. All these incidents did involve top brands. Have any of you had potential dangerous situations with factory ammunition?
