The .22 Long Rifle (.22 LR) and the .17 Hornady Magnum Rimfire (.17 HMR) are both popular rimfire cartridges, but they cater to different needs and preferences. This in-depth comparison will explore the key differences between these two rounds, helping you determine which is the right choice for your shooting endeavors.
Ballistics and Performance: A Tale of Two Cartridges
The most significant difference lies in their ballistic performance. The .17 HMR boasts substantially higher velocity and flatter trajectory, making it ideal for longer-range shots and varmint hunting. Conversely, the .22 LR is known for its affordability, versatility, and widespread availability.
Velocity and Energy
| Cartridge | Velocity (fps) | Energy (ft-lbs) |
|---|---|---|
| .22 LR (Standard) | 1070-1255 | 120-140 |
| .17 HMR | 2550-2650 | 200-220 |
As you can see, the .17 HMR significantly outperforms the .22 LR in both velocity and energy. This increased energy translates to a flatter trajectory and greater range, resulting in better accuracy at longer distances.
Trajectory and Range
The higher velocity of the .17 HMR results in a flatter trajectory. This means less bullet drop over distance, simplifying aiming and increasing accuracy at longer ranges. The .22 LR, while accurate at shorter ranges, experiences more significant bullet drop, limiting its effective range.
Example: At 100 yards, the .17 HMR will have significantly less bullet drop than a .22 LR, making it easier to hit a target with the same point of aim.
Accuracy
Both cartridges are capable of excellent accuracy, but the .17 HMR generally offers a tighter grouping at longer ranges due to its flatter trajectory and higher velocity. However, the accuracy of both rounds is heavily dependent on the quality of the ammunition, the rifle used, and the shooter's skill.
Applications and Uses: Finding the Right Fit
The ideal cartridge depends greatly on its intended use. Let's examine specific applications for each:
.22 LR: The Versatile Workhorse
- Target Shooting: Its affordability and low recoil make it perfect for plinking and target practice.
- Small Game Hunting: Suitable for hunting rabbits, squirrels, and other small game at closer ranges.
- Training: An excellent choice for firearm training due to its low cost and manageable recoil.
- Pest Control: Effective for controlling rodents and other pests around the property.
.17 HMR: The Long-Range Performer
- Varmint Hunting: Its high velocity and flat trajectory make it ideal for hunting prairie dogs, ground squirrels, and other varmints at longer ranges.
- Small Game Hunting (longer ranges): Effective for hunting small game at distances beyond the practical range of a .22 LR.
- Longer Range Target Shooting: Superior accuracy at distances exceeding those typically suitable for the .22 LR.
Cost and Availability: A Key Consideration
The .22 LR enjoys a significant advantage in terms of cost and availability. Ammunition is widely available and significantly cheaper than .17 HMR rounds. This makes the .22 LR a more economical choice for high-volume shooting.
However, the price difference should be weighed against the performance advantages offered by the .17 HMR, particularly for specific applications like long-range varmint hunting.
Rifle Considerations: Choosing the Right Platform
Both cartridges are chambered in a wide variety of rifles, ranging from simple bolt-action rifles to semi-automatic models. Selecting the appropriate rifle is crucial for optimizing accuracy and performance with either cartridge. Consider the features of the rifle when making your decision.
Conclusion: The Best Choice Depends on Your Needs
Ultimately, the "better" cartridge depends entirely on your intended use. The .22 LR is a versatile, affordable, and widely available option perfect for various applications. The .17 HMR offers superior performance at longer ranges, particularly for varmint hunting and longer-range target shooting, but at a higher cost. Consider your budget, intended use, and shooting style to make an informed decision.
