17 WSM vs 17 HMR: A Comprehensive Comparison for the Modern Shooter
The world of rimfire cartridges offers a diverse range of options for shooters, each with its own set of advantages and disadvantages. Two of the most popular and debated cartridges are the .17 Winchester Super Magnum (17 WSM) and the .17 Hornady Magnum Rimfire (17 HMR). Both offer flat trajectories and impressive accuracy, but they cater to slightly different needs and applications. This article provides a comprehensive comparison of the 17 WSM vs 17 HMR, delving into their ballistics, effective range, common uses, and overall suitability for various shooting scenarios. Understanding the nuances of each cartridge is crucial for making an informed decision based on your specific shooting requirements.
Understanding the Cartridges
The 17 HMR: A Rimfire Revolution
The 17 HMR, introduced in 2002 by Hornady, quickly gained popularity for its flat trajectory and enhanced accuracy compared to the .22 Long Rifle. It utilizes a necked-down .22 WMR case to fire a .17 caliber bullet, resulting in higher velocities and a flatter shooting experience. The 17 HMR is particularly well-suited for varmint hunting, target shooting, and small game hunting at moderate ranges.
The 17 WSM: Pushing the Boundaries of Rimfire
Winchester introduced the 17 WSM in 2012, aiming to push the performance limits of rimfire cartridges. Based on a modified .27 nail gun blank, the 17 WSM delivers significantly higher velocities and energy than the 17 HMR. This translates to flatter trajectories and greater effective range, making it a viable option for longer-range varmint hunting and situations where more stopping power is required. The 17 WSM cartridge offers a substantial leap in performance compared to other rimfire options.
Ballistics and Performance: 17 WSM vs 17 HMR
When comparing the 17 WSM vs 17 HMR, ballistics are a key differentiator. Let’s examine the specific numbers:
- Velocity: The 17 WSM typically achieves velocities of around 3,000 fps with a 20-grain bullet, while the 17 HMR reaches velocities of about 2,550 fps with a 17-grain bullet. This significant velocity difference gives the 17 WSM a flatter trajectory and greater resistance to wind drift.
- Energy: The higher velocity of the 17 WSM translates to more energy on target. A 20-grain 17 WSM bullet can deliver around 400 ft-lbs of energy at the muzzle, compared to approximately 245 ft-lbs for a 17-grain 17 HMR bullet.
- Trajectory: The flatter trajectory of the 17 WSM makes it easier to hit targets at longer ranges without significant holdover. This is especially advantageous for varmint hunting in open fields.
- Wind Drift: Due to its higher velocity and ballistic coefficient, the 17 WSM is less susceptible to wind drift than the 17 HMR. This is a critical factor for maintaining accuracy in windy conditions.
In summary, the 17 WSM offers superior ballistics compared to the 17 HMR, providing flatter trajectories, greater energy, and reduced wind drift. However, this performance comes at the cost of increased recoil and potentially higher ammunition prices.
Effective Range and Accuracy
Both the 17 WSM and 17 HMR are known for their accuracy, but their effective ranges differ. The 17 HMR is typically effective out to 150 yards, while the 17 WSM can maintain accuracy and energy out to 200 yards or even further, depending on the rifle and shooting conditions.

Common Uses and Applications
Varmint Hunting
Both cartridges are popular choices for varmint hunting, but their suitability varies depending on the target and the range. The 17 HMR is effective for smaller varmints like squirrels and prairie dogs at closer ranges. The 17 WSM, with its greater energy and range, is better suited for larger varmints like groundhogs and coyotes, especially at distances beyond 150 yards. The choice between the 17 WSM and 17 HMR often comes down to the specific varmint being targeted and the typical shooting distances involved.
Target Shooting
For target shooting, both cartridges offer excellent accuracy and are enjoyable to shoot. The 17 HMR is often preferred for its lower cost and milder recoil, making it a good choice for high-volume shooting. The 17 WSM can also be used for target shooting, but its higher cost and increased recoil may be a deterrent for some shooters.
Small Game Hunting
The 17 HMR is a popular choice for small game hunting, particularly for animals like rabbits and squirrels. Its accuracy and relatively low noise make it a good option for hunting in populated areas. The 17 WSM can also be used for small game hunting, but its higher energy may cause excessive damage to the meat, making it less desirable for some hunters. The 17 HMR generally provides a good balance of accuracy, power, and minimal meat damage for small game hunting.
Rifle Availability and Cost
Rifles chambered in 17 HMR are widely available from a variety of manufacturers, offering a broad range of options at different price points. The 17 WSM, while also available, has fewer rifle options compared to the 17 HMR. This limited availability can sometimes make it more challenging to find a rifle that meets specific preferences.

In terms of cost, 17 HMR ammunition is generally more affordable than 17 WSM ammunition. This cost difference can be significant, especially for shooters who engage in frequent target practice or high-volume varmint hunting. The higher cost of 17 WSM ammunition reflects its more complex manufacturing process and higher performance capabilities.
Recoil and Noise
Both the 17 WSM and 17 HMR have relatively low recoil compared to centerfire cartridges, making them comfortable to shoot for extended periods. However, the 17 WSM produces slightly more recoil than the 17 HMR due to its higher velocity and heavier bullets. This difference in recoil is generally not significant enough to be a major factor for most shooters, but it may be noticeable for those who are particularly sensitive to recoil.
In terms of noise, both cartridges are relatively quiet compared to centerfire options, but the 17 WSM is generally louder than the 17 HMR. This difference in noise level may be a consideration for hunters who are concerned about spooking game or shooting in areas with noise restrictions. The 17 HMR’s lower noise level can be advantageous in certain hunting situations.
