Definition and Mechanics of Rimfire Cartridges
The fundamental difference between rimfire and centerfire cartridges lies in the placement of the primer. In rimfire cartridges, the primer, typically a sensitive explosive compound, is contained within the rim of the cartridge case. This design is crucial to understanding how these guns operate.
So, how does it work? When the firearm’s firing pin strikes the rim of the cartridge, it crushes the rim, detonating the primer. This primer then ignites the main propellant charge, usually gunpowder, housed within the cartridge casing. The rapid expansion of the gases from the burning propellant propels the bullet out of the barrel. The simplicity of this design is one of the key factors contributing to the cost-effectiveness of rimfire ammunition. The relatively uncomplicated manufacturing process translates to lower production expenses, making rimfire guns a popular choice for both beginners and experienced shooters alike.
The rimfire cartridge itself comprises several key components, each playing a vital role in its function. The bullet, usually made of lead or a lead alloy, is the projectile designed to travel downrange and impact the target. The cartridge case, typically made of soft brass, houses the bullet and the propellant. The primer, as mentioned earlier, sits within the rim. Finally, the propellant, or gunpowder, provides the force necessary to launch the bullet. When the firing pin strikes the rim, the primer detonates, initiating the combustion of the propellant and driving the bullet forward.
Rimfire cartridges also offer several advantages. One of the most significant is their simplicity. This straightforward design results in lower manufacturing costs, as previously mentioned. Another benefit is the reduced recoil associated with many rimfire cartridges. The smaller powder charges used in these cartridges result in less felt recoil compared to larger caliber centerfire cartridges. This makes rimfire guns easier to handle, especially for beginners, and can make for a more enjoyable shooting experience over prolonged periods. Finally, in many cases, rimfire cartridges produce less noise than their centerfire counterparts.
However, the rimfire design is not without its disadvantages. One notable drawback is their relatively lower power compared to centerfire cartridges. The size limitations of the rimfire casing restrict the amount of propellant that can be used, thereby limiting the bullet’s velocity and kinetic energy. This makes rimfire cartridges less suitable for certain applications, such as hunting larger game. Furthermore, rimfire primers can sometimes be less reliable than those found in centerfire cartridges. The priming compound is spread thinly around the rim, and this can sometimes result in misfires. Perhaps the most significant limitation of rimfire cartridges is that they are generally *not* reloadable. Once fired, the case is discarded. This lack of reusability can impact long-term cost.
History of Rimfire Firearms
The development of rimfire ammunition marked a significant step forward in firearms technology. Its simplicity and affordability quickly made it popular. The origins of rimfire firearms can be traced back to the mid-19th century. Prior to their emergence, firearms were often muzzle-loading, a slow and cumbersome process. The advent of self-contained metallic cartridges, of which rimfire was a pioneer, greatly streamlined the reloading process.
Key figures and companies played instrumental roles in perfecting this technology. One name frequently associated with the development of rimfire cartridges is Louis-Nicolas Flobert, a French inventor. Flobert designed what is considered one of the earliest rimfire cartridges, which consisted of a bullet attached to a percussion cap. This innovation predated the development of smokeless powders and significantly improved the ease of use and efficiency of firearms. The subsequent invention of the self-contained cartridge, which integrated bullet, propellant, and primer into a single unit, further revolutionized the firearms industry.
Early rimfire calibers, such as the .22 Short, gained rapid popularity. The .22 Short, introduced around 1857, was a relatively low-powered round, ideal for target practice and plinking. Its popularity helped to pave the way for subsequent rimfire developments. Then came the .22 Long, and soon enough, further advancements made the rimfire even more commonplace.
The evolution of rimfire firearms mirrored advancements in ammunition. Improvements in manufacturing processes led to more reliable and accurate cartridges. This evolution is ongoing, with manufacturers constantly striving to enhance the performance and safety of rimfire firearms.

It is suitable for shooting at short distances, and its reduced noise level makes it appropriate for recreational shooting in areas with noise restrictions.
The .22 Long Rifle (LR) is, by far, the most popular rimfire cartridge. It strikes a balance between power, range, and affordability. The .22 LR’s versatility makes it a suitable choice for a variety of shooting activities, including target shooting, small game hunting, and recreational plinking. The widespread availability of .22 LR ammunition and its low cost further contribute to its enduring popularity. This is the standard by which many rimfire guns are measured.
The .22 Winchester Magnum Rimfire (.22 WMR), sometimes referred to as .22 Magnum, offers a significant performance upgrade over the .22 LR. The .22 WMR’s higher velocity and energy make it suitable for hunting larger small game and for applications where greater range and power are required. While more expensive than .22 LR, the .22 WMR offers increased performance for those who need it.
There are other less common rimfire cartridges, such as the .17 Hornady Magnum Rimfire (.17 HMR) and the .17 Mach 2. These are designed for specific applications, providing high velocity for varmint hunting and target shooting. Their niche use helps to keep the .22 LR as the most utilized.
