.22 LR Ammo: In Depth
The .22 Long Rifle, commonly known as .22 LR, is one of the most popular and widely used ammunition types in the world. Renowned for its low recoil, affordability, and versatility, this rimfire cartridge has become a staple for recreational shooters, small game hunters, and competitive marksmen alike. The .22 LR offers an impressive combination of accuracy and low noise, making it suitable for a wide range of applications from target practice to pest control and introductory firearms training.
History and Development
The .22 Long Rifle cartridge was developed in the United States during the late 19th century. It was introduced in 1887 by the J. Stevens Arms & Tool Company, evolving from earlier rimfire cartridges. The .22 LR was designed to be a low-cost, low-recoil round that could offer good accuracy for small game hunting and target shooting.
The development of the .22 LR was a significant milestone in firearms history. It combined the best attributes of its predecessors, the .22 Long and .22 Extra Long, creating a cartridge that offered improved performance in a compact package. This led to its rapid adoption and enduring popularity.
The .22 LR's design incorporated a heeled bullet, where the bullet diameter is the same as the case diameter, with a heel that fits inside the case. This unique feature, combined with its rimfire ignition system, contributed to its reliability and ease of manufacture, factors that have played a crucial role in its longevity.
Throughout the 20th century and beyond, the .22 LR gained immense popularity. It saw extensive use in Olympic shooting events, small game hunting, and as a training round for novice shooters. The cartridge's low cost and mild report made it ideal for high-volume shooting and indoor ranges.
In the civilian market, the .22 LR has experienced continuous growth in popularity. The widespread adoption of both bolt-action and semi-automatic rifles and pistols chambered in this caliber opened up new possibilities for shooters of all skill levels. Advancements in bullet design and manufacturing processes have further improved the .22 LR's performance, making it an even more versatile option for various shooting applications.
Today, the .22 LR remains one of the most produced and consumed ammunition types globally. Its widespread use has led to continuous innovation in ammunition design, with manufacturers offering a wide range of options from standard velocity target rounds to high-velocity hunting loads and subsonic variants for suppressed firearms. The .22 LR's enduring popularity is a testament to its versatility, affordability, and the pure enjoyment it brings to shooting sports.
Complete Timeline of .22 LR Development:

.22 LR: Effective Range for Different Applications
This table provides estimated effective ranges for .22 LR ammunition in various applications. Ranges are based on typical bullet weights and velocities.
| Application | Effective Range (yards) | Notes |
|---|---|---|
| Plinking/Target Practice | 0-100 | Ideal for recreational shooting and skill development |
| Small Game Hunting | 0-50 | Effective for rabbits, squirrels, and other small game |
| Pest Control | 0-25 | Suitable for rodents and other small pests |
| Competition Shooting | 0-50 | Used in various disciplines, including smallbore rifle competitions |
| Training | 0-25 | Excellent for firearm familiarization and basic marksmanship training |
Note: Effective ranges can vary based on factors such as bullet selection, shooter skill, wind conditions, and specific firearm characteristics. The .22 LR is known for its low recoil and affordability, making it ideal for high-volume practice. Always prioritize safety and adhere to local laws and regulations.
.22 LR: Barrel Length Effects on Performance
Barrel length can affect .22 LR performance, though to a lesser extent than centerfire cartridges. This chart illustrates the impact of different barrel lengths on velocity.
2" (Short-barreled pistol) - 850 fps
4" (Standard pistol) - 950 fps
16" (Standard rifle) - 1070 fps
20" (Long rifle) - 1100 fps
Understanding Barrel Length Effects
Barrel length affects .22 LR performance in several ways:
- Longer barrels generally provide slightly higher velocities, but the effect is less pronounced than with centerfire cartridges.
- Shorter barrels offer better maneuverability, making them popular for pistols and compact rifles.
- Velocity increases tend to plateau after about 16 inches of barrel length for .22 LR.
- Accuracy can be affected by barrel length, with longer barrels potentially offering better sight radius and stability.
The chart above visualizes how velocity increases with barrel length, with the width of each bar representing the relative velocity.
Note: Velocities are approximate and based on standard velocity .22 LR loads. Actual velocities can vary based on specific ammunition, environmental conditions, and individual firearms. Always chronograph your specific gun/ammo combination for precise data.

Estimated Barrel Life Comparison
This chart provides a general comparison of estimated barrel life for .22 LR and similar rimfire cartridges. Actual barrel life can vary significantly based on factors such as firing schedule, ammunition quality, and maintenance.
| Cartridge | Estimated Barrel Life (Rounds) |
|---|---|
| .22 LR |
|
| .22 WMR |
|
| .17 HMR |
|
| .17 WSM |
|
| .22 Hornet |
|
Note: These are rough estimates and can vary greatly depending on usage, load data, cleaning regimen, and individual firearm characteristics. High-volume shooters may see shorter lifespans, while casual shooters might experience longer barrel life. Rimfire cartridges generally have longer barrel life due to their lower pressures and velocities compared to centerfire cartridges.
Sectional Density Comparison
Sectional density is a measure of a bullet's mass relative to its diameter. Higher sectional density generally indicates better penetration and energy retention.
| Cartridge | Bullet Weight (gr) | Sectional Density | Relative SD |
|---|---|---|---|
| .22 LR | 40 | 0.114 |
|
| .22 WMR | 40 | 0.114 |
|
| .17 HMR | 17 | 0.084 |
|
| .17 WSM | 20 | 0.099 |
|
| .22 Hornet | 45 | 0.129 |
|
Note: Sectional density is calculated as (bullet weight in pounds) / (bullet diameter in inches)². Higher sectional density generally indicates better penetration, but other factors like velocity and bullet construction also play significant roles in overall performance. For rimfire cartridges, the differences in sectional density are less pronounced compared to larger centerfire cartridges.
22LR: Frequently Asked Questions:
.22 Short, .22 Long, and .22 Long Rifle
Small game only – rabbit, squirrel, and similarly sized animals. Groundhogs and prairie dogs will certainly succumb to this round but you might have trouble hitting them, given the effective hunting range of this round (50-75yds max). Smaller predators like foxes at close range. However, a centerfire rifle cartridge would be a much better choice for this purpose, as .22LR has a higher probability of simply wounding an animal this size if you don’t make a good shot.
This is not the cartridge for self defense – unless you have no other option. .22LR handguns are, for the most part, unreliable. .22WMR is only slightly larger and carries a lot more energy, as do centerfire options like .30 Super Carry, .380 ACP, etc. Consider one of these if your goal is carrying something smaller than 9mm.
Probably not! However, if squirrels are the only likely home invaders in your situation, then maybe.
While you can get fairly reliable results with a well maintained quality rifle and premium ammunition, .22LR still has a higher probability for FTFs (failures to fire) than anything centerfire. This is definitely an instance where you want a boom after every click! Bottom line: stick with a centerfire gun for home defense, unless a .22LR is all you have.
