When the group is huddled at the top of the stairs, Braker asks Deputy Bob how he is doing on ammo. The Deputy checks his revolver and says "Not so good...4 shots left." Later, when the Collector gets past the bloodshield, and the Demons are convening on the group, Deputy Bob yells at Braker and the others to get into the attic while he covers the rear. While the others are climbing into the attic, Deputy Bob fires off six rounds at the demons, instead of four.
Brayker shoots The Collector through the eye with an arrow just after he's collected the key from Roach. You can see the section of the arrow shaft that sticks out the back of The Collector's head bend as his head hits the floor after he falls over the upstairs railing and crashes through the coffee table.
