Description
I remember the first time I took a .17 WSM rifle out to a friend’s farm near Columbia. We were overrun with groundhogs, and the standard .22 LR just wasn’t cutting it for those longer, windy shots. That’s when I truly understood the niche this round fills. So, what is the Winchester Varmint HV .17 Win Super Mag 20gr, V-Max, 50rds/Box? It’s a high-velocity, flat-shooting rimfire cartridge designed for precise, explosive varmint control at extended ranges where traditional .22 LR falls short. Think of it as a laser beam for pests.
Look, if you’re tired of lobbing rounds at prairie dogs or watching a crow flap away after a solid hit with lesser ammo, this is the solution. I’ve put several boxes of this specific load through my Savage B-Mag and a few Ruger 77/17s, and the performance is consistently impressive. The 20-grain V-Max bullet is the star of the show—it’s engineered for rapid fragmentation upon impact, which translates to devastating terminal effect on small game with minimal pelt damage for fur hunters. The “HV” stands for High Velocity, and Winchester isn’t kidding. You’re looking at muzzle velocities pushing well over 3,000 feet per second, which for a rimfire is just wild.
Here’s the thing—the .17 WSM cartridge itself bridges a critical gap. It offers centerfire-like trajectory and wind-bucking ability in a rimfire platform, which often means a lighter, simpler rifle. The 50-round box at $21.99 gives you a solid range session or a productive afternoon in the field without breaking the bank. This ammo is drop-in ready for rifles chambered in .17 Winchester Super Magnum, requiring no gunsmithing or modification. It ships to Missouri and compliant US states, so whether you’re in the Bootheel or the Northwest grasslands, you can get it.

Pros: The hyper-flat trajectory makes connecting at 150-200 yards feel easy. The V-Max bullet’s explosive expansion is incredibly effective on varmints. The nickel-plated brass cases feed smoothly and resist corrosion. It’s also one of the most affordable ways to experience near-centerfire performance.
Cons: You need a dedicated .17 WSM rifle—this won’t work in a .17 HMR or any .22. Barrel fouling can be a bit more pronounced than with some rounds, so regular cleaning is a good habit. And, like all high-velocity .17s, wind deflection becomes a real factor past 200 yards, though it’s still better than a .22.
So who is this for? Primarily, it’s for the serious varminter who wants to stretch their rimfire’s legs. If you’re managing ground squirrel towns, dispatching raccoons in the henhouse, or hunting prairie dogs, this is your huckleberry. It’s also a fantastic choice for introducing a shooter to the challenges and rewards of longer-range shooting without the cost and recoil of a centerfire. It pairs perfectly with rifles like the Savage B-Mag, Ruger 77/17 in WSM, or the Browning A-17.
Frequently Asked Questions
Q: Can I shoot this .17 WSM ammo in my .17 HMR rifle?
A: Absolutely not. The .17 Winchester Super Magnum is a larger, more powerful cartridge. Firing it in a .17 HMR chamber is extremely dangerous and will cause a catastrophic failure. Always match your ammunition to your firearm’s specific chamber marking.
Q: How does the trajectory compare to a .22 Magnum?
A: It’s not even close. The .17 WSM shoots significantly flatter. Where a .22 WMR might have a 4-inch drop at 150 yards, the .17 WSM with this 20gr load will be around 1.5 inches, making holdovers much simpler and misses due to range miscalculation less likely.
Q: Is this good for fox or coyote?
A: For fox, with precise shot placement, it can be adequate. For coyote, I’d recommend stepping up to a centerfire. The .17 WSM is best suited for varmints and pests up to the size of a raccoon or groundhog. The goal is ethical, immediate kills, and the V-Max is designed for rapid energy transfer on smaller targets.
If the idea of a rimfire that punches way above its weight class and turns long-range pest control into a confident exercise sounds right for you, this Winchester Varmint HV load is the place to start. Check availability at firearms-missouri.com for Missouri residents and nationwide.
