The .22LR is a rimfire cartridge, meaning the primer is located in the rim of the cartridge case. This design simplifies manufacturing and contributes to its low cost. Typical .22LR bullets weigh between 30 and 40 grains, and muzzle velocities range from subsonic (around 1,080 fps) to supersonic (over 1,200 fps), depending on the load. Common bullet types include lead round nose, hollow point, and copper-plated.

Versatility in Application

The .22LR’s versatility is unmatched. It’s suitable for:

• Plinking: Its low cost makes it ideal for casual target shooting.
• Small Game Hunting: Effective for squirrels, rabbits, and other small game at reasonable ranges.
• Target Practice: An excellent training round for beginners due to its low recoil and manageable noise.
• Pest Control: Can be used to dispatch small pests like rodents and birds.

Exploring the .17 HMR: The High-Velocity Option

The .17 Hornady Magnum Rimfire (.17 HMR) is a relatively newer cartridge, introduced in 2002. It quickly gained popularity for its flat trajectory and impressive accuracy, particularly at longer ranges. Let’s examine its defining characteristics.

A Modern Rimfire Cartridge

The .17 HMR was developed by necking down a .22 Magnum case to accept a .17 caliber bullet. This design results in a significantly higher velocity and flatter trajectory compared to the .22LR.

Key Features and Specifications

The .17 HMR typically uses a 17-grain bullet, and muzzle velocities are typically around 2,550 fps. This high velocity results in a much flatter trajectory than the .22LR, making it easier to hit targets at longer distances. Common bullet types include polymer-tipped and hollow point.

Specialized Applications

The .17 HMR excels in situations where accuracy and range are paramount:

• Long-Range Target Shooting: Its flat trajectory makes it easier to hit targets at 100 yards and beyond.
• Small Game Hunting at Longer Ranges: Provides a significant advantage over the .22LR when hunting small game at extended distances.
• Pest Control in Open Areas: Its higher velocity and flatter trajectory make it more effective for controlling pests in open fields or orchards.

Head-to-Head Comparison: .22LR vs .17 HMR

Now, let’s compare the .22LR and .17 HMR across several key performance categories.

Ballistics and Trajectory

This is where the .17 HMR truly shines. Its higher velocity results in a significantly flatter trajectory than the .22LR. For example, a typical .17 HMR load will drop only a few inches at 100 yards, whereas a .22LR will drop much more significantly. This flatter trajectory makes the .17 HMR easier to shoot accurately at longer ranges, reducing the need for holdover.

Accuracy

Both cartridges are capable of excellent accuracy, but the .17 HMR generally has an edge, especially at longer ranges. Its flatter trajectory and higher velocity minimize the effects of wind and gravity, resulting in tighter groups. However, rifle quality and shooter skill play a significant role in achieving optimal accuracy with either cartridge. Based on expert consensus, a skilled marksman can achieve sub-MOA accuracy with a quality .17 HMR rifle.

Effective Range

The .22LR is generally considered effective out to around 75 yards, while the .17 HMR extends that range to 150 yards or more. The .17 HMR’s higher velocity and flatter trajectory allow it to maintain its energy and accuracy at longer distances.

Stopping Power

While neither cartridge is known for its overwhelming stopping power, the .17 HMR generally delivers more energy on target than the .22LR. The .17 HMR’s higher velocity creates a more dramatic impact, making it more effective for dispatching small game quickly and humanely. In our experience, a well-placed shot with a .17 HMR is often more decisive than a similar shot with a .22LR.

Recoil and Noise

Both cartridges produce very little recoil, making them comfortable to shoot for extended periods. However, the .22LR generally has slightly less recoil than the .17 HMR. Similarly, the .22LR is typically quieter than the .17 HMR, especially when using subsonic ammunition. This difference in noise level can be a significant factor for shooters who are sensitive to loud sounds or who are hunting in areas where noise is a concern.

Cost and Availability

The .22LR is significantly cheaper and more readily available than the .17 HMR. This is due to its widespread popularity and simpler manufacturing process. In times of ammunition shortages, the .22LR is typically easier to find than the .17 HMR. The lower cost of .22LR ammunition makes it a more practical choice for high-volume shooting and casual plinking.

Rifle and Ammunition Selection

The .22LR boasts a wider selection of rifles and ammunition than the .17 HMR. This gives shooters more options to choose from based on their specific needs and preferences. .22LR rifles are available in a variety of action types, including bolt-action, semi-automatic, and lever-action. Ammunition choices range from inexpensive bulk packs to high-quality match-grade rounds. While .17 HMR rifle selection is growing, it still lags behind the .22LR.

The Role of Barrel Length and Twist Rate

The barrel length and twist rate of your rifle can significantly impact the performance of both the .22LR and .17 HMR cartridges. A longer barrel generally results in higher velocities, while a faster twist rate can improve accuracy with certain types of ammunition. Understanding these factors can help you optimize your rifle for the specific cartridge and application.

Optimizing for .22LR

For .22LR, a barrel length of 16-20 inches is generally considered optimal. A twist rate of 1:16 is common and works well with most .22LR ammunition. Shorter barrels can be used for compact rifles or pistols, but they will result in lower velocities.

Optimizing for .17 HMR

For .17 HMR, a barrel length of 20-22 inches is often preferred. A twist rate of 1:9 is standard and provides good accuracy with the typical 17-grain bullets. Shorter barrels can be used, but they may not fully utilize the .17 HMR’s high velocity potential.
