Understanding the .17 WSM and .17 HMR: A Deep Dive
Let’s explore these two popular rimfire rounds in detail.
.17 Winchester Super Magnum (WSM): The High-Velocity Powerhouse
The .17 WSM, introduced by Winchester in 2012, is the fastest rimfire cartridge currently available. It achieves impressive velocities, often exceeding 3,000 feet per second (fps) with lighter bullets. This high velocity translates to a flatter trajectory and increased energy on target, making it a potent choice for varmint hunting at extended ranges. The .17 WSM’s case is based on a .27 caliber nail gun blank, necked down to accept a .17 caliber bullet. This robust case design allows for higher pressures and, consequently, higher velocities than the .17 HMR.
.17 Hornady Magnum Rimfire (HMR): The Accurate and Versatile Option
The .17 HMR, developed by Hornady in 2002, quickly gained popularity for its exceptional accuracy and relatively flat trajectory compared to other rimfire cartridges like the .22 Long Rifle. It typically pushes a 17-grain bullet at around 2,550 fps. The .17 HMR is based on a .22 WMR case, necked down to accept a .17 caliber bullet. Its accuracy and manageable recoil make it a favorite among target shooters and varmint hunters alike.
Ballistics Comparison: Velocity, Trajectory, and Energy
Ballistics are crucial in determining a cartridge’s performance. Let’s compare the .17 WSM and .17 HMR in terms of velocity, trajectory, and energy.
Velocity: Speed Kills (and Hits Harder)
The .17 WSM holds a significant velocity advantage over the .17 HMR. Typical .17 WSM loads can achieve velocities of 2,600-3,000 fps with 20-grain bullets, while the .17 HMR typically reaches around 2,550 fps with a 17-grain bullet. This higher velocity gives the .17 WSM a flatter trajectory and more energy downrange.
Trajectory: The Flatness Factor
Due to its higher velocity, the .17 WSM exhibits a flatter trajectory than the .17 HMR. This means that the bullet drops less over a given distance, making it easier to hit targets at longer ranges without needing to compensate as much for bullet drop. While both rounds are considered flat-shooting compared to the .22 LR, the .17 WSM offers a distinct advantage in this area. In our experience, the difference becomes noticeable beyond 150 yards.
Energy: Impact on Target
The .17 WSM’s higher velocity also translates to greater energy on target. This increased energy can be crucial for ethical varmint hunting, ensuring a clean and humane kill. While the .17 HMR is certainly capable of dispatching varmints effectively, the .17 WSM provides a greater margin of error, especially at longer distances. Based on expert consensus, the .17 WSM offers approximately 50% more energy at 100 yards compared to the .17 HMR.
Accuracy: Precision is Paramount
While the .17 WSM boasts impressive ballistics, the .17 HMR has earned a reputation for exceptional accuracy. Many shooters find the .17 HMR easier to shoot accurately, due to its lower recoil and often more consistent ammunition. However, advancements in .17 WSM ammunition and rifle manufacturing have narrowed this gap.
.17 HMR: The Accuracy Standard
The .17 HMR has long been praised for its inherent accuracy. This is often attributed to its smaller case capacity, which leads to more consistent powder burn and bullet seating. Many .17 HMR rifles are capable of sub-MOA (minute of angle) accuracy, meaning they can consistently shoot groups of less than one inch at 100 yards. This level of precision makes the .17 HMR ideal for target shooting and varmint hunting where precise shot placement is critical.
.17 WSM: Closing the Accuracy Gap
While the .17 WSM has historically been perceived as less accurate than the .17 HMR, recent advancements have significantly improved its accuracy potential. Modern .17 WSM rifles, coupled with high-quality ammunition, are now capable of achieving excellent accuracy, often rivaling that of the .17 HMR. However, it’s important to note that .17 WSM ammunition can be more variable in quality than .17 HMR, so careful selection of ammunition is crucial for achieving optimal accuracy.
Effective Range: How Far Can You Reach?
Effective range is a critical consideration for varmint hunters. Both the .17 WSM and .17 HMR offer extended range compared to other rimfire cartridges, but the .17 WSM provides a distinct advantage due to its flatter trajectory and higher energy.
.17 WSM: Reaching Out Further
The .17 WSM’s higher velocity and flatter trajectory allow it to maintain its accuracy and energy at longer ranges. Many experienced shooters consider the .17 WSM to be effective out to 200 yards or even further, depending on the target size and wind conditions. This extended range makes it well-suited for hunting in open areas where longer shots are common.
.17 HMR: A Practical Range Limit
While the .17 HMR is certainly capable of hitting targets at longer ranges, its effectiveness diminishes beyond 150 yards. The bullet’s trajectory becomes more pronounced, and its energy decreases significantly. Most experienced shooters consider 150 yards to be the practical maximum range for the .17 HMR, especially for ethical varmint hunting. Recent studies indicate that beyond this range, the .17 HMR may lack the necessary energy for a humane kill.
