Explore the fascinating history and surprising truths about .22 ammo, from its longevity and design flaws to its unexpected lethality. This blog post reveals ten shocking insights that every gun owner should understand about the world's most popular cartridge.
The .22 long rifle cartridge is often seen as simple, cheap, and harmless, but it holds a rich history and surprising capabilities that many owners overlook. In this post, we will uncover ten shocking truths about .22 ammo that every shooter should know, revealing the hidden history, science, and myths surrounding this popular cartridge.
The .22 rimfire is the oldest self-contained metallic cartridge still in production today. Its story began in 1857 with the .22 short, developed for the first Smith and Wesson revolver, followed by the .22 long rifle in 1887. This means that the .22 ammo we use today is a direct link to the black powder era, surviving and thriving for over 160 years. While modern powders and primers have improved, the fundamental design has remained unchanged, making it a true relic of history.
If you've ever left the range with filthy hands after shooting .22 ammo, there's a reason. Most .22 ammunition is designed to be dirty. Unlike centerfire rounds that use clean-burning powders and fully jacketed lead projectiles, bulk .22 ammo typically features unjacketed lead bullets coated in a waxy lubricant. This design, combined with faster-burning powders, results in significant fouling that requires regular cleaning of your firearm.
Rimfire ammunition is inherently less reliable than centerfire ammunition, primarily due to its priming system. In rimfire cartridges, the priming compound is a wet paste that is spun into the hollow rim of the case. This process can lead to inconsistencies, resulting in duds when the firing pin fails to ignite the primer. This unreliability is a significant reason why .22 ammo is not recommended for self-defense.
The .22 long rifle is the best suppressor host cartridge available, often without needing special ammunition. The loud crack of a gunshot consists of the muzzle blast and the supersonic crack of the bullet breaking the sound barrier. Most centerfire rounds are supersonic, but standard velocity .22 ammo typically travels at speeds that can be subsonic when fired from shorter barrels, resulting in a quieter shooting experience.
Not all .22 long rifle ammunition is the same size, and some can be dangerous in the wrong firearm. Hyper velocity loads, like the CCI Stinger, use a slightly longer case and lighter bullet, which can jam in rifles with tight chambers. This can lead to dangerous pressure spikes if fired improperly, highlighting the importance of understanding your firearm's specifications.
.22 ammunition is notoriously inconsistent, not just between brands but also from one production lot to another. Due to the high-volume, low-margin nature of its production, tolerances can be loose, leading to variations in performance. This inconsistency is why competitive shooters often test multiple lots to find the best match for their firearms.
There are .22 ammo types that do not use gunpowder, such as the Aguila Calibri and Super Calibri. These cartridges rely solely on the primer for propulsion, producing a sound quieter than a high-powered air rifle. However, they come with a critical safety warning: the low power can cause bullets to get stuck in the barrel, leading to dangerous situations if another round is fired.
The .22 long rifle played a tragic role in the infamous 1997 North Hollywood bank robbery. During the shootout, a police officer armed with a .22 revolver found his shots ineffective against the robbers' body armor. This event highlighted the limitations of .22 ammo in defensive situations and led to significant changes in law enforcement armament.
During times of panic, .22 ammo is often the first to disappear from shelves. This phenomenon is driven by both economics and psychology. As the cheapest cartridge, it is the most affordable option for bulk purchases, leading to hoarding behavior. Additionally, manufacturers prioritize higher-margin centerfire ammo during shortages, exacerbating the scarcity of .22.
Despite its limitations, the .22 long rifle is surprisingly lethal. While it is not recommended for self-defense due to its unreliability and low stopping power, its small, unstable projectile can create fatal wounds. The bullet often tumbles upon impact, causing unpredictable damage. This paradox serves as a reminder that even small cartridges can be dangerous and should be treated with respect.
The .22 long rifle is a fascinating study in contrasts. It is a historical relic that remains popular, a simple tool for fun that also presents complex challenges for shooters. Understanding its strengths and weaknesses is essential for responsible gun ownership. What shocking truth about .22 ammo did we miss? Share your thoughts and experiences in the comments below.
