Many firearms have a mechanism (the extractor) that grabs the rim of a cartridge case (or the extractor groove) that makes the cartridge case move with the bolt when it moves. As the bolt moves to the rear, the fired case is drawn with it. When it is fully withdrawn, part of the mechanism flips the case out of the firearm (ejection). Not all guns have ejectors- top break shotguns may extract the fired shell, but some require you to eject by pulling the fired shell with your fingers.

How are bullet casings and bullets used to compare and identify guns used in crimes?
The barrel of a gun has lans and grooves that cause the bullet to spin. These grooves leave distinct markings on the bullet that are like a fingerprint. No two guns leave the same markings on a bullet. The bullet casings are marked by both the firing pin hitting the primer or case rim, and the extractor that grabs the case and ejects it from the weapon. These are also distinct, gun specific, markings.
What does police his brass mean?
When you fire most guns, the gun will eject the brass cartridge the holds the bullet, gun powder, and primer. The firing pin of the gun hits the primer at the base of the cartridge, which ignites the gun powder and fires the bullet. As the explosion occurs and the bullet leaves the barrel of gun, the mechanism of the gun uses the explosion's energy to eject the now empty brass cartridge.'Policing the brass' means to pick up the spent cartridges after your done firing.

No, to reject is to exclude from consideration when considering whether or not to select something. The object does not need to be physically manipulated in any way.

Is there a way to know exactly which gun fired the bullet if there are several guns and several bullets?
