But really isn't it the practice of checking the barrel after each shot for debris that determines the possibility of an accident?
Another question, how many times would a gun have to be shot for there to be wear on the barrel wall?

Checking the barrel for debris only prevents an obstruction leading to a burst barrel. The "wear" on a shotgun barrel referred to is due to not wear but by removing metal by reaming. I've always measured the bore and chamber diameters and if they are within specs for the gauge then that's good enough for my purposes.
