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

The .17 WSM and .17 HMR are both rimfire cartridges, meaning the primer is located in the rim of the cartridge. However, they differ significantly in their design, performance, and intended use. Let’s explore each round in detail.

The .17 Winchester Super Magnum (17 WSM)

The .17 WSM is the newer of the two cartridges, introduced by Winchester in 2012. Its claim to fame is its exceptionally high velocity, making it the fastest rimfire cartridge currently available. The .17 WSM is based on a modified .27 caliber nail gun blank, necked down to accept a .17 caliber bullet. This robust design allows it to handle significantly higher pressures than other rimfire cartridges, resulting in its impressive velocity.

* **History and Development:** The .17 WSM was designed to fill a gap in the market between the .22 WMR and centerfire cartridges like the .223 Remington. Winchester aimed to create a rimfire round with a flatter trajectory and greater energy than existing options.
* **Core Concepts:** The key to the .17 WSM’s performance is its high pressure and small, lightweight bullet. This combination results in a very flat trajectory and significant energy on target, especially at longer ranges.
* **Current Relevance:** The .17 WSM remains a popular choice for varmint hunting and target shooting, particularly where longer ranges are required. Its high velocity and flat trajectory make it easier to hit small targets at distances where other rimfire cartridges struggle.

The .17 Hornady Magnum Rimfire (17 HMR)

The .17 HMR was introduced by Hornady in 2002 and quickly gained popularity for its accuracy and flat trajectory compared to the .22 LR. The .17 HMR is based on a .22 WMR case necked down to accept a .17 caliber bullet. While not as fast as the .17 WSM, the .17 HMR offers excellent accuracy and a flatter trajectory than most other rimfire cartridges.

* **History and Development:** The .17 HMR was designed to provide a more accurate and longer-range alternative to the .22 LR. Hornady’s engineers focused on creating a cartridge that would be inherently accurate and easy to shoot.
* **Core Concepts:** The .17 HMR’s accuracy is attributed to its consistent case dimensions, high-quality bullets, and relatively high velocity. The small, lightweight bullet provides a flat trajectory and minimal wind drift.
* **Current Relevance:** The .17 HMR remains a popular choice for varmint hunting, target shooting, and small game hunting. Its accuracy and relatively low recoil make it a good option for shooters of all skill levels.
