As a seasoned hunter and outdoor writer, I’ve spent years evaluating different cartridges for various applications. One question I consistently encounter is: “What’s the difference between the 17 WSM vs. 17 Hornet?” Both are excellent rimfire options gaining popularity for varmint hunting and small game, but they aren’t interchangeable. This article will provide a detailed comparison, covering ballistics, effective range, ideal uses, and cost, helping you determine which cartridge best suits your needs. We’ll also look at how these compare to other popular rimfire options like the .22LR.
Understanding the Basics: 17 WSM and 17 Hornet
Both the 17 Winchester Super Magnum (WSM) and the 17 Hornet are relatively new cartridges designed to push rimfire performance beyond the limitations of the traditional .22 Long Rifle. They offer flatter trajectories, increased velocity, and extended range, making them ideal for targeting small game and pests at distances where .22LR struggles. However, they achieve this through different design philosophies and have distinct characteristics.
What is the 17 WSM?
The 17 WSM, introduced in 2004, is based on a modified .22 WMR (Winchester Magnum Rimfire) case necked down to accept a .17 caliber bullet. This design allows it to generate higher velocities than .22LR, offering a flatter trajectory and improved downrange energy. It’s known for its accuracy and effectiveness on small varmints like prairie dogs, ground squirrels, and rabbits. Winchester is the primary manufacturer of 17 WSM ammunition and rifles.
What is the 17 Hornet?
The 17 Hornet, released in 2012, takes a different approach. It’s based on the .223 Remington case, also necked down to .17 caliber. This larger case capacity allows for even higher velocities and flatter trajectories than the 17 WSM. The 17 Hornet is considered a more potent cartridge, capable of taking slightly larger varmints and extending effective range. Hornady spearheaded the development of the 17 Hornet and remains a major producer of ammunition.
Ballistics Breakdown: 17 Hornet vs. 17 WSM
Let's dive into the numbers. Ballistics are crucial when choosing a cartridge, as they directly impact accuracy and effectiveness. Here’s a comparison of typical loads for both cartridges (data sourced from manufacturer specifications and independent testing):
| Characteristic | 17 WSM | 17 Hornet |
|---|---|---|
| Bullet Weight (gr) | 15.5 - 20 | 20 - 25 |
| Velocity (fps) | 2,000 - 2,100 | 2,100 - 2,200 |
| Energy (ft-lbs) | 270 - 320 | 350 - 420 |
| Trajectory Drop (inches at 200 yards) | ~5-6 | ~3-4 |
| Maximum Effective Range (estimated) | 150-200 yards | 200-250 yards |
As you can see, the 17 Hornet generally boasts higher velocities, energy, and a flatter trajectory. This translates to a longer effective range and greater accuracy at distance. However, the difference isn’t always dramatic, and the 17 WSM remains a very capable cartridge within its optimal range.
Practical Applications: Where Each Cartridge Shines
The best cartridge for you depends on what you plan to hunt and where you’ll be hunting. Here’s a breakdown of ideal applications for each:
17 WSM: Ideal for…
- Small Varmints: Prairie dogs, ground squirrels, chipmunks, and rabbits are all excellent targets for the 17 WSM.
- Close to Medium Range: Within 150-200 yards, the 17 WSM delivers excellent accuracy and sufficient energy for clean kills.
- Beginner Rimfire Shooters: The milder recoil of the 17 WSM makes it a good choice for those new to rimfire shooting.
- Areas with Shooting Restrictions: In some areas, high-velocity rimfire cartridges like the 17 WSM may be permitted where centerfire rifles are prohibited.
17 Hornet: Ideal for…
- Larger Varmints: Woodchucks, badgers, and even small coyotes can be effectively targeted with the 17 Hornet.
- Longer Range Shooting: The flatter trajectory and increased energy of the 17 Hornet make it suitable for shots out to 250 yards or more.
- Windy Conditions: The heavier bullets used in 17 Hornet loads are less affected by wind drift than those typically used in 17 WSM.
- Experienced Rimfire Shooters: The slightly sharper recoil of the 17 Hornet is manageable for experienced shooters.
Consider your typical hunting scenarios. If you primarily target small varmints at close range, the 17 WSM is a fantastic option. If you need more range and power for larger pests, the 17 Hornet is the better choice. Remember to always check local hunting regulations before using any cartridge. The National Park Service provides information on hunting regulations in national parks, and state wildlife agencies have specific rules for each state.
Cost and Availability: 17 WSM vs. 17 Hornet
Cost and availability are important factors to consider. Historically, both cartridges have been more expensive than .22LR, and availability can fluctuate.
Ammunition Costs
Generally, 17 WSM ammunition is slightly less expensive than 17 Hornet ammunition. However, prices vary significantly depending on the brand, bullet type, and quantity purchased. Expect to pay a premium for both compared to .22LR. As of late 2023/early 2024, a box of 50 rounds of 17 WSM typically ranges from $20-$30, while a box of 50 rounds of 17 Hornet can range from $25-$40.
Rifle Costs
Rifles chambered in 17 WSM and 17 Hornet are also typically more expensive than .22LR rifles. You’ll find a wider selection of 17 WSM rifles, as it’s been on the market longer. 17 Hornet rifles are becoming more common, but may have a higher price tag. Consider the cost of both the rifle and ongoing ammunition expenses when making your decision.
Rifle Platforms and Considerations
Both cartridges are available in a variety of rifle platforms, including bolt-action, semi-automatic, and single-shot rifles. REI’s expert advice section offers a good overview of rifle types. When choosing a rifle, consider factors like accuracy, ergonomics, and intended use. Pay attention to barrel length, as it can affect velocity and accuracy. A heavier barrel can improve accuracy by reducing barrel vibration.
Beyond the Comparison: Other Rimfire Options
Before making a final decision, it’s worth considering other rimfire options. The .22LR remains the most popular and affordable rimfire cartridge, offering excellent versatility for plinking, target shooting, and small game hunting. However, it lacks the range and flat trajectory of the 17 WSM and 17 Hornet. The .22 Magnum (WMR) offers a step up in performance from .22LR, but still doesn’t match the ballistics of the 17 WSM or 17 Hornet.
Safety and Responsible Shooting
Regardless of which cartridge you choose, always prioritize safety. Follow the four rules of gun safety:
- Always point the muzzle in a safe direction.
- Always keep your finger off the trigger until ready to shoot.
- Always keep the action open and unloaded until ready to use.
- Be sure of your target and what is beyond it.
Final Thoughts: Choosing the Right Cartridge
The 17 WSM vs. 17 Hornet debate doesn’t have a single right answer. Both are excellent cartridges with unique strengths and weaknesses. The 17 WSM is a fantastic choice for close-range varmint hunting and offers a milder shooting experience. The 17 Hornet provides more range, power, and wind resistance, making it ideal for larger pests and longer shots. Carefully consider your hunting needs, budget, and shooting experience to determine which cartridge is the best fit for you. I hope this detailed comparison has helped you make an informed decision!
