[QUOTE="brcfo_outdoors, post: 2809971, member: 113623"] The chamber being the portion of the barrel that houses the cartridge when it is in the firing position. If it isn't finished properly, as in a rough chamber, once the cartridge is fired the brass expands and fire forms to the shape of the chamber. If the chamber surface isn't smooth, friction is created as you try to extract the case which the chamber now fits like the proverbial glove. Primary extraction becomes extremely difficult, especially as the barrel heats up and the metal expands. Unless the chamber was extremely rough, I doubt you would notice the problem on a new gun until you shot for a while and the barrel heated up. At least with a metallic cartridge. I had an 870 Express which had a rough chamber as well, and it was apparent the first time I fired it. Had to mortar that thing to get the action to cycle. [/QUOTE]
