Hi Rob,
Basically it is a reaming operation to cut a "chamber" in the end of a barrel that holds the cartridge to be fired. Special reamers are made to provide very specific clearances and match the contours of a particular cartridge/caliber. It is critical that this chamber is perfectly aligned and concentric with the inner bore of the barrel.
