Our goal is to provide an expert, trustworthy, and helpful resource that clarifies the key differences and empowers you to choose the best rimfire round for your shooting endeavors.
Understanding the .17 Winchester Super Magnum (17 WSM)
The .17 Winchester Super Magnum (17 WSM) is a rimfire cartridge introduced in 2012 by Winchester. It was designed to deliver significantly higher velocities and flatter trajectories than other rimfire cartridges, bridging the gap between traditional rimfires and centerfire cartridges. The 17 WSM is essentially a .27 caliber nail gun blank necked down to accept a .17 caliber bullet. This robust design allows for much higher pressures compared to other rimfire rounds.
Core Concepts and Advanced Principles
The key to the 17 WSM’s performance lies in its high pressure and case design. Unlike the .17 HMR, which is based on a .22 WMR case, the 17 WSM utilizes a larger and stronger case to handle pressures exceeding 33,000 PSI. This higher pressure translates to increased velocity and a flatter trajectory. The bullet is typically a 20-grain projectile, but variations exist.
Importance and Current Relevance
The 17 WSM fills a specific niche for shooters who require a rimfire cartridge with extended range and higher velocities for varmint hunting and target shooting. Recent trends indicate a growing interest in the 17 WSM for applications where a lightweight, low-recoil cartridge with minimal wind drift is desired. Its relatively low cost per round compared to many centerfire options also makes it an attractive choice for high-volume shooting.
Exploring the .17 Hornady Magnum Rimfire (17 HMR)
The .17 Hornady Magnum Rimfire (17 HMR) is another popular rimfire cartridge, introduced in 2002. It was designed to provide a flatter trajectory and greater accuracy than the .22 WMR. The 17 HMR is based on a .22 WMR case necked down to accept a .17 caliber bullet.
Core Concepts and Advanced Principles
The .17 HMR achieves its performance through a combination of a lightweight bullet and a relatively high velocity. Typical bullet weights range from 17 to 20 grains. The cartridge operates at lower pressures than the 17 WSM, making it suitable for a wider range of rimfire rifles.
Importance and Current Relevance
The 17 HMR has become a favorite among varmint hunters and target shooters due to its flat trajectory, accuracy, and manageable recoil. It’s particularly well-suited for situations where pinpoint accuracy is required at moderate distances. Its popularity continues to grow, driven by the availability of a wide variety of rifles and ammunition.
Ballistic Performance: 17 WSM or 17 HMR
When evaluating 17 WSM or 17 HMR, ballistic performance is a critical factor. The 17 WSM generally offers higher velocities and a flatter trajectory than the 17 HMR. Let’s compare the typical ballistic data:
* **17 WSM (20-grain bullet):** Muzzle velocity around 3,000 fps, energy around 400 ft-lbs.
* **17 HMR (17-grain bullet):** Muzzle velocity around 2,550 fps, energy around 245 ft-lbs.
This difference in velocity translates to a flatter trajectory and increased energy at longer ranges for the 17 WSM. However, the 17 HMR still provides a very flat trajectory and sufficient energy for many varmint hunting applications.
Ammunition Availability and Cost
Ammunition availability and cost are essential considerations when choosing between 17 WSM or 17 HMR. The 17 HMR is generally more readily available and less expensive than the 17 WSM. This is due to the 17 HMR’s longer history and greater popularity.
While 17 WSM ammunition is becoming more widely available, it may still be more difficult to find in some regions. The cost per round is typically higher for 17 WSM than for 17 HMR. Shooters who engage in high-volume shooting may find the lower cost of 17 HMR ammunition to be a significant advantage.
Rifle Availability and Selection
The availability of rifles chambered in 17 WSM or 17 HMR is another crucial factor. The 17 HMR enjoys a wider selection of rifles from various manufacturers. Bolt-action, semi-automatic, and single-shot rifles are commonly available in 17 HMR.
Rifles chambered in 17 WSM are less numerous but still available from several manufacturers. Bolt-action rifles are the most common type available in 17 WSM. When selecting a rifle, consider factors such as barrel length, trigger quality, and overall ergonomics.
Effective Range and Accuracy
Effective range and accuracy are paramount for both varmint hunting and target shooting. The 17 WSM offers a longer effective range than the 17 HMR due to its higher velocity and flatter trajectory. The 17 WSM can effectively reach targets out to 200 yards or more, while the 17 HMR is typically most effective within 150 yards.
Both cartridges are known for their excellent accuracy. In our experience, both can achieve sub-MOA accuracy in rifles with quality barrels and optics. However, wind drift can be more pronounced with the 17 HMR due to its lower bullet weight and velocity.
Common Uses and Applications
The 17 WSM or 17 HMR each excel in different applications. The 17 HMR is a popular choice for varmint hunting (ground squirrels, prairie dogs, rabbits) and target shooting at moderate distances. Its flat trajectory and accuracy make it well-suited for these tasks.
The 17 WSM is often preferred for varmint hunting at longer ranges (coyotes, foxes, larger rodents) and target shooting where minimal wind drift is desired. Its higher velocity and energy provide greater knockdown power at extended distances.
Recoil and Noise
Recoil and noise levels are important considerations, especially for new shooters or those sensitive to recoil. Both the 17 WSM and 17 HMR produce very little recoil, making them comfortable to shoot for extended periods. The 17 HMR typically generates slightly less recoil than the 17 WSM.
In terms of noise, both cartridges are relatively loud compared to .22 LR. However, the 17 WSM tends to be louder than the 17 HMR due to its higher pressure and larger case volume. Hearing protection is always recommended when shooting either cartridge.
