Most push feed mechanisms use a spring loaded plunger type of ejector situated at the breech face, and this system ejects the spent casing as soon as the case mouth clears the ejection port. [9] Most controlled feed mechanisms use a fixed mechanical ejector attached to the receiver, which results in the bolt having to be pulled all or almost ...
Most modern extractors are forceful enough to completely eject the casing from the gun (i.e. integrating the function of an ejector), but some require the user to manually remove spent cartridges. In this situation, the extractor loosens and moves the case out of the chamber just far enough to allow the user to grab and pull out the casing, but ...
Rimless cases are not well suited to break-open and revolver actions, though in break-action firearms they can be used with appropriate modifications, such as a spring-loaded extractor/ejector or, in a revolver, a half or full moon clip (for example, the Colt or Smith & Wesson M1917 revolvers in .45 ACP).

Direct impingement operation increases the amount of heat that is deposited in the receiver while firing, which can burn off and cover up lubricants. The bolt, extractor, ejector, pins, and springs are also heated by the same high-temperature gas. These combined factors reduce service life of these parts, reliability, and mean time between ...

It is a common issue for calibers with large rims, such as 7.62×54mmR , or guns that have been rechambered for cartridges shorter than intended without replacing the original magazine with one that compensates for the shorter round.
