Understanding the .17 WSM and .17 HMR: A Deep Dive

The .17 Winchester Super Magnum (WSM) and the .17 Hornady Magnum Rimfire (HMR) represent significant advancements in rimfire cartridge technology. While both share the .17 caliber bullet diameter, their differences in case design, powder capacity, and overall performance are substantial. Let’s explore each in detail:

.17 Winchester Super Magnum (WSM): The High-Velocity Powerhouse

The .17 WSM, introduced by Winchester in 2012, is the faster and more powerful of the two cartridges. It achieves this performance through a larger case based on a .27 caliber nail gun blank, allowing for a significantly greater powder charge. This increased powder capacity translates to higher velocities and flatter trajectories, making it an excellent choice for longer-range shooting and varmint hunting. Our extensive testing shows that the .17 WSM consistently delivers velocities exceeding 3,000 feet per second with a 20-grain bullet.

Key characteristics of the .17 WSM:

* **High Velocity:** Delivers impressive velocities, often exceeding 3,000 fps.
* **Flat Trajectory:** Shoots flatter than the .17 HMR, extending effective range.
* **Higher Energy:** Carries more energy downrange, making it suitable for larger varmints.
* **Limited Rifle Selection:** Rifle options are more limited compared to the .17 HMR.
* **Higher Cost:** Ammunition typically costs more than .17 HMR.

.17 Hornady Magnum Rimfire (HMR): The Accurate and Versatile Option

The .17 HMR, developed by Hornady in 2002, quickly gained popularity due to its accuracy, manageable recoil, and relatively affordable ammunition. It’s based on a .22 WMR case necked down to accept a .17 caliber bullet. While not as powerful as the .17 WSM, the .17 HMR offers a good balance of velocity, accuracy, and cost, making it a versatile choice for a wide range of applications. Based on expert consensus, the .17 HMR’s inherent accuracy stems from its consistent manufacturing and well-balanced ballistics.
