A QUICK "PRIMER" ON 17 WSM AMMO
The .17 Winchester Super Magnum (17 WSM), launched by Winchester in 2013, stands as the fastest commercial rimfire cartridge ever produced. Engineered from a modified .27-caliber industrial nail gun blank, the 17 WSM fires a 20-grain projectile at velocities up to 3,000 feet per second, delivering explosive energy, minimal drop, and impressive accuracy out to extended ranges. This high-speed, flat-shooting round is purpose-built for long-range varmint hunting and precision rimfire shooting.
Shooters often compare the 17 WSM vs. 17 HMR, and while both are .17 caliber rimfire rounds, the difference in performance is substantial. The 17 WSM offers a significant velocity and energy advantage, making it superior for engaging coyotes, prairie dogs, and other pests at longer distances. However, due to its larger case and higher chamber pressure, the 17 WSM must be fired from a rifle specifically chambered for it; it is not interchangeable with 17 HMR firearms.
For ammunition options, Winchester’s Varmint HV and Hornady’s V-MAX lines are standout choices. Winchester offers 20-grain and 25-grain polymer-tipped loads designed for rapid expansion and effective terminal impact. Hornady’s V-MAX, trusted for its superior accuracy and explosive expansion, is a go-to for those seeking long-range consistency and small-game effectiveness. Brands like Browning and American Eagle also offer dependable rimfire loads that cater to hunters and target shooters alike.
Top Considerations When Buying 17 WSM Ammo
When selecting 17 WSM ammo, it’s important to match your load selection with your shooting goals—whether you’re hunting varmints or zeroing in at 200+ yards. Here are the key factors to consider:
Purpose: The .17 Winchester Super Magnum is built for high-speed performance, making it an excellent choice for varmint hunting, coyote control, and long-range rimfire shooting. Its ultra-flat trajectory and explosive terminal effect make it a favorite among precision shooters and pest hunters. For casual plinking or budget-friendly practice, however, other rimfire calibers like .22 LR or 17 HMR may be more economical.
Bullet Weight: Most 17 WSM ammo is available in either 20-grain or 25-grain configurations. 20-grain bullets offer maximum velocity and flatter trajectories, ideal for shooting prairie dogs, squirrels, or jackrabbits at longer distances. 25-grain bullets fly slightly slower but carry more energy and resist wind drift better, great for predator hunting in open fields or breezy conditions.
Choosing a Manufacturer: Stick with trusted names that deliver proven rimfire performance. Winchester, the cartridge’s developer, produces several well-regarded options in its Varmint HV line. Hornady’s V-MAX loads are another favorite among long-range shooters, known for their explosive expansion and precision accuracy. You’ll also find dependable offerings from Browning and American Eagle, all available here at Target Sports USA.
Availability and Bulk Value: Because the 17 WSM is a niche rimfire caliber, it may not be as widely stocked as .22 LR or 17 HMR. To ensure uninterrupted range time or hunting readiness, consider purchasing bulk 17 WSM ammo when available. At Target Sports USA, we offer free shipping on bulk cases, helping you save while staying fully stocked.
