This article will serve as a guide, providing insights into the technical specifications, performance characteristics, practical considerations, and suitable applications for both the .22 LR and the .22 WMR. Understanding the differences between these two rounds will allow you to make an informed decision when choosing a firearm or selecting the best ammunition for your specific shooting needs.
Delving into Technical Details and Ballistics
Exploring the core specifications and ballistic properties of each cartridge is crucial for understanding their differences.
Examining the .22 LR
The .22 LR typically employs a bullet that weighs between forty and sixty grains. The most common weights sit around forty grains, making this the standard. Muzzle velocity is typically below 1300 feet per second (fps), though this can vary based on the specific ammunition used and the length of the firearm’s barrel. This moderate velocity translates into a muzzle energy, which generally hovers around 100-180 foot-pounds (ft-lbs).
The effective range of a .22 LR is generally considered to be around 100 yards, although accurate shooting can be achieved at greater distances with skilled shooters and favorable conditions. However, the bullet’s trajectory begins to drop significantly beyond this range, making it less suitable for long-range targets.
The .22 LR is a favorite choice for a broad spectrum of uses. These include plinking (informal target shooting), target practice at shooting ranges, and small-game hunting such as squirrels and rabbits. Furthermore, its low recoil makes it an excellent training tool for new shooters, children, and those sensitive to recoil.
The .22 LR operates through the straightforward mechanism of a rimfire ignition. Upon the firing pin striking the rim of the cartridge, it crushes the priming compound, which is located within the rim. This ignition initiates the rapid combustion of the propellant, propelling the bullet down the barrel.
Understanding the .22 WMR
The .22 WMR typically fires a bullet that is heavier, most commonly in the forty to fifty grain range. These bullets are generally heavier than those of the .22 LR, leading to a greater retained velocity and energy at longer ranges. The higher-velocity cartridge provides a much flatter trajectory.
The .22 WMR delivers a substantially higher muzzle velocity. Most .22 WMR loads boast speeds in excess of 1,900 fps, and some can even exceed 2,000 fps, depending on the ammunition and barrel length. This increased velocity translates into a much higher muzzle energy, often exceeding 300 ft-lbs.
The effective range of the .22 WMR extends beyond that of the .22 LR, often reaching 150 yards and, in some cases, even further with skilled shooters. The flatter trajectory and higher retained energy allow for more accurate shots at greater distances.
The .22 WMR finds its niche in applications where greater power and range are needed. This includes hunting larger varmints, such as prairie dogs, groundhogs, and coyotes. It is also suitable for taking down small game at ranges that would be difficult or irresponsible with a .22 LR.
The .22 WMR utilizes the same rimfire ignition principle as the .22 LR. However, the .22 WMR’s larger case holds a considerably greater amount of propellant, contributing to the higher velocity and energy. The primer is ignited by a strike on the rim, igniting the powder and pushing the bullet.

Performance in Practice: Accuracy, Range, and Beyond
Beyond the technical specifications, understanding the practical performance of each cartridge is essential.
The Quest for Precision
Both the .22 LR and .22 WMR can be accurate, but there are differences that shooters must be aware of. The .22 LR, due to its slower velocity, is often more affected by external factors like wind. The quality of the firearm and ammunition significantly impacts .22 LR accuracy.
The .22 WMR, with its higher velocity, tends to have a slightly flatter trajectory and is less susceptible to wind drift, especially at longer ranges. However, the inherent accuracy of the firearm and the quality of the ammunition remain critical.
Extending the Reach: Range and Trajectory Explained
The difference in velocity translates directly into a different trajectory. The .22 WMR has a much flatter trajectory than the .22 LR. This means that, at a given distance, the bullet drops less. This flatter trajectory makes aiming and compensating for bullet drop easier at extended ranges.
This flatter trajectory translates to an extended effective range for the .22 WMR. This makes it a superior choice for shooting at longer distances and engaging targets that may be beyond the effective range of a .22 LR.
The Power to Stop: Terminal Ballistics and Impact
The .22 WMR delivers significantly more energy on impact, leading to greater stopping power. This increased energy translates into deeper penetration and a greater likelihood of anchoring a target. This is a crucial consideration for hunters who want to ensure an ethical and clean kill.
The .22 LR is often considered suitable for taking down small game, but it can be less effective on larger varmints. It may also result in a greater chance of wounding and not killing a game animal.
The .22 WMR is better suited for hunting larger varmints, and is much more likely to put down an animal with one well placed shot.
Handling and Feel
The .22 LR is famous for its incredibly low recoil. This makes it a comfortable cartridge to shoot for shooters of all ages and experience levels, including those new to firearms. The .22 WMR has more recoil, but it’s generally still considered manageable for most shooters.
Finding the Right Ammo: Availability and Cost
The .22 LR remains one of the most readily available and inexpensive rimfire cartridges. It is sold virtually everywhere that sells ammunition. This widespread availability, combined with its low cost, makes it an ideal choice for budget-conscious shooters and those who enjoy frequent practice.
The .22 WMR is generally more expensive than the .22 LR. While not as readily available as the .22 LR, it’s not difficult to find in most gun stores, especially in areas with a lot of varmint hunting.
Guns and Gear: Firearm Availability and Price
Firearms chambered in .22 LR are plentiful and generally more affordable than those chambered in .22 WMR. Bolt-action rifles, semi-automatic rifles, and pistols are all commonly available in .22 LR.
