For example, "7.62×54mmR" is a rimmed cartridge, while "7.62×51mm" is a rimless cartridge. [2], On a "rimless" case, the rim has almost or exactly the same diameter as the base of the case; the recess formed between the rim and the body of the cartridge is known as an extractor groove, since it forms a lip which can be grasped by an extractor to extract the empty case after being fired.

This can be a problem for magnum revolvers or rifles which simultaneously chamber more than one round of ammunition, as the recoil from the firing successive rounds can loosen the bullets in the remaining cartridges, and cause their bullet seating depth to change, which can have a serious effect on accuracy, or could, in the case of a revolver, cause a bullet to protrude sufficiently from the front of the cylinder to obstruct the revolving of the cylinder thus jamming the gun from firing additional rounds. Cordite was extruded as spaghetti-like rods, so the cartridge cases had to be fairly cylindrical shaped to accommodate the cordite propellant rods. The cases of most military rifles and machine guns have a bottleneck shape, allowing a small-calibre bullet to be fitted… These also serve an important functional purpose in feeding and extraction of the cartridge within the gun mechanism. Typically, handgun cartridge cases are straight walled and rifle cartridge cases are of the bottleneck type.
