Some cartridges, like the .470 Capstick, have what is known as a "ghost shoulder" which has a very slightly protruding shoulder, and can be viewed as a something between a bottleneck and straight-walled case. A ghost shoulder, rather than a continuous taper on the case wall, helps the cartridge to line up concentrically with the bore axis ...
Rimmed cartridges use the rim to hold the (usually straight sided) 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". Because the rimmed cartridge headspaces on the rim, the case length is of less importance than with rimless cartridges.
Headspace positioning of rimless, rimmed, belted and straight cartridges Several different rimmed, .22 rimfire cartridges, which have a uniform forward diameter, and which have headspace on the rim, allowing any length of cartridge shorter than the maximum size to be used in the same firearm Firearms chambered for tapered rimmed cartridges like this .303 British cannot safely fire shorter ...
– Shortened to an overall case length of 1.70 in (43 mm), with the bottleneck expanded to a straight wall to accept a .41 caliber bullet. Designed in Michigan, one of several states that have changed deer hunting regulations in recent years to allow the use of large-caliber straight-wall centerfire cartridges (for Michigan, such requirements ...
Introduced by Remington at the 2023 SHOT Show. Straight-walled cartridge based on a blown-out .30-30 Winchester case and designed for deer hunting in U.S. states that require hunters with modern rifles to use that cartridge shape.

It was produced in two variants: the bottleneck case .43 Spanish (11.15x57mmR Remington Spanish) and the straight-wall case .43 Spanish Reformado (11.4x57mmR Reformado). [ 2 ] The cartridge was very similar to the .44-77 Sharps cartridge, except for the difference in their case dimensions. [ 7 ]
Although originating from an identical preceding series of experimental cartridges, the commercial 1952 .308 Winchester and the military 1954 7.62×51mm NATO chamberings have evolved separately but remain similar enough that they can be loaded into rifles chambered for the other round, but the .308 Winchester cartridges are typically loaded to ...
Rimless, straight wall cases, on the other hand, require a taper crimp, because they have headspace on the case mouth; roll crimping causes headspacing problems on these cartridges. Rimmed, belted, or bottleneck cartridges, however, generally can safely be roll crimped when needed. Three dies are normally supplied for straight-walled cases ...
