A lot depends on the ammo as well concerning bullet set back. Some aren't as tight as others.
At my old department I had two boxes on the counter in the armory labeled top rounds. When a person unloaded their gun for any reason the chambered round went into a coffee can and they took a new round out of the top round box. One for the duty caliber (45 when I left) and 223 for their rifles.
I generally do as Scott mentioned and rotate the round lower in the mag "IF" it looks ok. If not it get set aside and replaced.
