From the size of the pellet strikes, it looks like a bird-shot load. If it had been magnum .00 buckshot, it would have sliced the Iphone and the victim to shreds.
True. . . but normally a bird shot load is an excellent home protection load in a twelve guage. It will take out the baddie and won't go through the too many walls and take out your children sleeping down the hall. . . even if a few pellets get down there, individually they have only a small amount of energy and won't do much injury.
