However, cases described as semi-rimmed are usually visually distinguishable from similar rimless cases. There are various types of firearms rims in use in modern ammunition.

These two kinds of ammo are named according to how the primer ignition system works. Rimmed cartridges use the rim to hold the cartridge in the chamber of the firearm, with the rim serving to hold the cartridge at the proper depth in the chamber—this function is called "headspacing". All small arms cartridges have a flange at the base of the case called a rim.The part of the firearm called an extractor claw hooks over the rim to extract the spent case from the chamber after it has been fired.

Rimmed cartridges use the rim to hold the cartridge in the chamber of the firearm, with the rim serving to hold the cartridge at the proper depth in the chamber—this function is called "headspacing". Since a straight-walled rimless cartridge is designed to headspace off of the case mouth, this prevents the ammunition loader or manufacturer from using a heavy crimp, which is a ring pinched or "crimped" into the cartridge case, designed to lock the bullet securely in place until fired. Semi-rimmed cartridge cases have an extraction groove and a rim very slightly larger than the diameter of the cartridge case. [3], One example of a rebated rim cartridge is the .50 Action Express (or .50 AE), commonly chambered in the Desert Eagle pistol. Thus, rimmed cartridges are sometimes called "flanged" cartridges. This means that the extraction claw also has to fit within the chamber, and therefore the case has a rebated rim. Belted cartridge cases have a thicker ‘belt’ positioned just above the extraction groove, and rebated cases have a rim that is smaller in diameter than the cartridge case. Rimmed cartridges have a rim or extractor flange of larger diameter than the case base, often with a grooved or undercut area immediately ahead of the rim.

The original purpose of the "belt" on belted cases (often referred to as belted magnums) was to provide headspacing; the extractor groove is cut into the belt just as it is cut into the case head on a rimless case. This round is used in specialized AR-15 upper receivers, and the rim matches the size of the rim of the 7.62×39mm, allowing those parts to be used in the custom-built upper receivers.[7]. Also, note that naming a case design “semi-rimmed” versus “rimmed” is strictly a subjective call—there is no specified difference in base diameter and rim diameter that automatically separates these two styles. Semi-automatic handguns have been chambered in rimmed cartridges as well, for example a LAR Grizzly or Desert Eagle in .357 Magnum or .44 Magnum. Small-arms cartridges, based upon type ridge cases are illustrated in figure 2. of case, are classified as centerfire or rim fire. These lists contain the current popular calibres and some wildcats. Rimmed. The belt acts as a rim on what is essentially a rimless case. The cartridge base and rim type are important identifying features. Rimmed cartridges generally do not work quite as well in firearms that feed from a box magazine, since the magazine must be carefully loaded so that the rim from each successive case is loaded ahead of the round beneath it, so the round will not snag on the rim of the cartridge below it as the bolt strips it out of the magazine. The first differentiator is between rimfire and centerfire cartridges.. Typically, handgun cartridge cases are straight walled and rifle cartridge cases are of the bottleneck type. 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. Since there is no rim projecting past the edge of the case, the cartridge must headspace on the case mouth, for a straight walled case, or on the case's shoulder for a bottlenecked case (although a bottlenecked case can headspace on the case mouth, depending on the cartridge); the extractor groove serves only for extraction. Get the latest news and reviews from Gundigest.com. The rimfire’s primer is built into the rim while the centerfire cartridge has the primer in the center. (ii) Semi-rimmed.
