So Far. I have never had a factory round fail in any centerfire rifle or handgun. I have had misfires with rimfire though. I carry only factory loads for defense. Makes sense to me with the legal factors involved.

As a civilian I have never had to fire in self defense but have on occassion stopped an ugly incident by showing a handgun. I also helped a guy who was stalking my daughter set a new one block speed record by racking the slide on a 1911.
