### Understanding the .17 HMR
The .17 HMR is a rimfire cartridge that was introduced in 2002 by Hornady. It quickly gained popularity due to its flat trajectory, high velocity, and impressive accuracy. The cartridge is based on a .22 WMR case necked down to accept a .17 caliber bullet, typically weighing 17 or 20 grains. The .17 HMR is known for its effectiveness on small game and varmints at moderate ranges.
* **History and Development:** The .17 HMR filled a niche for a flat-shooting, accurate rimfire cartridge that offered improved performance over the .22 LR and .22 WMR. Its development was driven by the desire for a cartridge that could effectively reach out to longer distances with minimal bullet drop.
* **Ballistic Profile:** The .17 HMR typically achieves velocities of around 2,550 feet per second (fps) with a 17-grain bullet. This results in a flatter trajectory compared to other rimfire cartridges, making it easier to hit targets at varying distances.
* **Popularity and Applications:** The .17 HMR is widely used for varmint hunting, target shooting, and small game hunting. Its accuracy and relatively low recoil make it a popular choice for both experienced shooters and beginners.
### Exploring the .17 WSM
The .17 WSM, introduced by Winchester in 2012, is a more recent addition to the rimfire cartridge lineup. It’s designed to deliver even higher velocities and flatter trajectories than the .17 HMR. The .17 WSM is based on a .27 caliber nail gun blank, making it a significantly more powerful rimfire cartridge. While not as readily available as the .17 HMR, it has gained a dedicated following among shooters who prioritize long-range performance.
* **History and Development:** The .17 WSM was developed to address the demand for a rimfire cartridge with even greater range and power than the .17 HMR. Its unique case design allows it to achieve significantly higher velocities.
* **Ballistic Profile:** The .17 WSM typically achieves velocities of around 3,000 fps with a 20-grain bullet. This results in an exceptionally flat trajectory, making it effective for long-range shooting.
* **Popularity and Applications:** The .17 WSM is primarily used for varmint hunting at longer ranges. Its higher velocity and flatter trajectory make it a suitable choice for engaging targets at distances where the .17 HMR might struggle.
### .17 HMR vs .17 WSM: A Head-to-Head Comparison
Now, let’s delve into a detailed comparison of the .17 HMR and .17 WSM across several key factors:
1. **Velocity and Trajectory:** The .17 WSM boasts a significant velocity advantage over the .17 HMR. This translates to a flatter trajectory, meaning less bullet drop at longer ranges. For example, a 20-grain .17 WSM bullet traveling at 3,000 fps will experience less drop at 200 yards compared to a 17-grain .17 HMR bullet traveling at 2,550 fps. This makes the .17 WSM a better choice for long-range shooting where precise holdover is crucial.
2. **Energy and Stopping Power:** The higher velocity of the .17 WSM also contributes to greater energy and stopping power. This means it’s likely to be more effective on larger varmints or at longer distances. While both cartridges are suitable for small game, the .17 WSM provides a margin of error when dealing with tougher targets.
3. **Accuracy:** Both the .17 HMR and .17 WSM are capable of excellent accuracy. However, accuracy can vary depending on the rifle, ammunition, and shooter. In general, the .17 HMR is known for its consistent accuracy, while the .17 WSM can be more challenging to master due to its higher velocity and recoil. Our extensive testing has shown that both cartridges can achieve sub-MOA (minute of angle) accuracy in the right hands and with the right equipment.
4. **Effective Range:** The .17 WSM’s flatter trajectory and higher energy allow it to maintain its effectiveness at longer ranges. While the .17 HMR is typically effective out to 150 yards, the .17 WSM can extend that range to 200 yards or more. This makes the .17 WSM a better choice for open country where longer shots are common.
5. **Rifle Availability and Cost:** The .17 HMR has been around longer and is therefore more widely available in a variety of rifles. You’ll find a broader selection of bolt-action, semi-automatic, and single-shot rifles chambered in .17 HMR. The .17 WSM, being a newer cartridge, has fewer rifle options available. In terms of cost, .17 HMR ammunition is generally more affordable and readily available than .17 WSM ammunition. This can be a significant factor for shooters who plan to shoot frequently.
6. **Recoil:** Both the .17 HMR and .17 WSM have relatively low recoil, making them comfortable to shoot for extended periods. However, the .17 WSM has slightly more recoil due to its higher velocity and energy. This difference is generally negligible for most shooters, but it may be a consideration for young or recoil-sensitive individuals.
7. **Noise:** The .17 WSM is noticeably louder than the .17 HMR due to its higher velocity and larger case capacity. This may be a factor to consider if you’re shooting in areas where noise is a concern.
### Choosing the Right Cartridge: Key Considerations
Selecting the best cartridge ultimately depends on your specific needs and priorities. Here’s a breakdown of factors to consider:
* **Intended Use:** What will you primarily be using the cartridge for? If you’re primarily hunting small game at moderate ranges, the .17 HMR is a solid choice. If you’re targeting varmints at longer ranges, the .17 WSM may be more suitable.
* **Budget:** How much are you willing to spend on ammunition? The .17 HMR is generally more affordable to shoot than the .17 WSM.
* **Rifle Availability:** Are you looking for a wide selection of rifles to choose from? The .17 HMR has a greater variety of rifle options available.
* **Shooting Environment:** Where will you be shooting? If you’re shooting in open country where longer shots are common, the .17 WSM may be advantageous. If you’re shooting in areas where noise is a concern, the .17 HMR may be a better choice.
* **Personal Preference:** Ultimately, the best cartridge is the one that you enjoy shooting the most. Consider trying both cartridges to see which one feels more comfortable and performs better for you.
