Because the rimmed cartridge headspaces on the rim, the case length is of less importance than with rimless cartridges.
In what type of weapon is a rimmed cartridge employed?
revolver cartridges. Most revolver cartridges are rimmed at the base of the case, which seats against the edge of cylinder chamber to provide headspace control (to keep the cartridge from moving too far forward into the chamber) and to facilitate easy extraction.

What is the difference between a rimless and rimless cartridge?
