Choosing the right rimfire cartridge can be a surprisingly complex decision. Two popular contenders often top the list: the .17 Winchester Super Magnum (WSM) and the .17 Hornady Magnum Rimfire (HMR). Both offer flat trajectories and enhanced accuracy compared to the .22 LR, but they cater to different needs and applications. This comprehensive guide dives deep into the 17 WSM vs 17 HMR debate, providing you with the knowledge to make an informed choice. We will explore their ballistics, performance, real-world applications, and ultimately, which cartridge reigns supreme for your specific shooting requirements.

Understanding the .17 WSM and .17 HMR Cartridges

To truly understand the 17 WSM vs 17 HMR comparison, we need to look at each cartridge individually. The .17 HMR, introduced in 2002, quickly gained popularity for its flat trajectory and varmint-hunting capabilities. It’s based on a .22 WMR case necked down to accept a .17 caliber bullet. The .17 WSM, released in 2012, takes the .17 caliber concept to a new level. It utilizes a completely new case design, offering significantly higher velocities and energy than the .17 HMR. This difference in case design is the heart of the 17 WSM vs 17 HMR debate. Let’s delve into the specifics of each.

The .17 WSM is a more potent cartridge, suitable for larger varmints and even small predators. However, this increased power comes at a cost. The .17 WSM generates more recoil and noise than the .17 HMR, and ammunition tends to be more expensive. Its performance makes it a compelling option when comparing 17 WSM vs 17 HMR.

Ballistic Performance: Trajectory, Velocity, and Energy

The ballistic performance is a crucial factor when comparing 17 WSM vs 17 HMR. Let’s examine the trajectory, velocity, and energy of each cartridge at different ranges.

Trajectory Comparison

The .17 WSM exhibits a flatter trajectory than the .17 HMR, meaning it drops less over a given distance. This is due to its higher velocity. A flatter trajectory makes it easier to hit targets at longer ranges without having to compensate as much for bullet drop. While both are flatter shooting than a .22LR, the .17 WSM offers a distinct advantage in minimizing holdover, especially beyond 150 yards.

Velocity Retention

The .17 WSM retains its velocity better than the .17 HMR. This means that the bullet slows down less over distance. Higher velocity results in greater energy and a flatter trajectory. The .17 WSM’s superior velocity retention contributes to its increased effective range and terminal performance. In our experience, this difference is noticeable when engaging targets beyond 200 yards.

Energy Transfer

The .17 WSM delivers significantly more energy on target than the .17 HMR. This is due to its higher velocity and heavier bullet options. Greater energy translates to more stopping power, making the .17 WSM a better choice for larger varmints and small predators. The additional energy also increases the likelihood of a clean, ethical kill. Experts agree that for animals like coyotes at reasonable ranges, the .17 WSM is a more humane option than the .17 HMR.
