An extractor also performs the function of an ejector in revolvers. When the striking force applied to the ejector rod is hard and fast enough, the extractor will typically eject the empty case(s) from the cylinder. Some break-action shotguns are also designed to eject empty shells completely out of the chamber when the barrel is opened.

[3] To clean and protect the part during the plating process, a combination of heat treating, cleaning, masking, pickling, and etching may be used. [1]
Because nickel-plated Merwin and Hulbert pistols had the same cost as those without, it is rare to find Merwin and Hulbert revolvers with a blued finish. A key innovation was a rotating barrel design which allowed the user to rotate the barrel 90 degrees in order to pull the barrel and cylinder forward to remove the fired cartridge cases.

A series of individual 1/1,000,000-second exposures showing shotgun firing shots and wadding separation. In shotgun shells, the wadding is actually a semi-flexible cup-shaped sabot designed to hold numerous much smaller-diameter sub-projectiles (i.e. shots), and is launched out together as one payload-carrying projectile.
Handloading ammunition avoids the labor costs of commercial production lines, reducing the expenditure to only the cost of purchasing components and equipment.Reloading may not be cost effective for occasional shooters, as it takes time to recoup the cost of needed equipment, but those who shoot more frequently will see cost-savings over time, as the brass cartridge cases and shotgun shell ...
