Sunday Gunday: New .17 WSM Savage A17 Rifles for Varminting
The .17 Winchester Super Magnum (aka .17 WSM) is the fastest, flattest-shooting rimfire cartridge ever created. The .17 WSM cartridge, as you can see below, is significantly larger than the .17 HMR, and can deliver a 3000-fps muzzle velocity with a 20gr bullet, compared to about 2375 fps for .17 HMR 20gr ammo. That’s 26% more speed, which translates to a much flatter trajectory — a big deal when you’re shooting small varmints out to 300 yards.

New .17 WSM A17 Semi-Auto Rifles from Savage Arms
The .17 WSM has been around for a while, but there have been limited selections of rifles chambered for this speedy rimfire round. Savage is changing that. Savage just announced that it will offer its A17-series rifles chambered in .17 WSM. Currently choose from two models with laminated wood stocks: the A17 WSM Sporter and A17 WSM Target Thumbhole. Both rifles feature a delayed-blowback, semi-automatic action specifically designed for the 17 HMR and 17 WSM cartridges. And both rifles boast 22″ button-rifled barrels, user-adjustable AccuTriggers, and 10-round rotary-feed internal magazines.
Between the two, the Target Thumbhole model ($709 MSRP) would be our choice for varmint work, as the stock has nice ergonomics and shoots better off the bags, with a thicker, wider forearm. The A17 WSM Target Thumbhole model also has a 22″ fluted heavy target barrel. This is better for high-volume varmint sessions than the standard-contour barrel on the Sporter model ($619 MSRP).
Savage Action Should Work Well with the .17 WSM Cartridge
Savage is proud of its new .17 WSM rifles: “We are launching the A17 chambered for .17 WSM in two of our more popular configurations [with laminate stocks]. Both are designed for target shooting and varmint hunting applications[.] The new A17 WSM Sporter and A17 WSM Target Thumbhole pair the dynamic rimfire cartridge with Savage’s A Series semi-automatic action for exceptional accuracy and fast follow-up shots.”“Savage has seen outstanding performance from the .17 WSM cartridge and felt it could be optimized in new platforms. The A Series rifles have a delayed blowback design that accommodates this caliber with limited modifications, making it an ideal action for the WSM cartridge.” — Jessica Treglia, Savage Arms Senior Brand Manager.

Commentary — This Could be a Great Varmint Option, IF the Ammo Becomes Available
If we were in the market for a new rifle for serious, high-volume ground squirrel and prairie dog varmint safaris, we would seriously consider this new A17 in .17 WSM. With a rimfire cartridge you don’t have to bother with handloading. And you should enjoy significantly better barrel life than a larger centerfire cartridge burning much more powder — provided you don’t shoot too fast and over-heat your barrel. Also, you won’t struggle to find primers. However, unfortunately .17 WSM ammo is hard to find right now, as we explain below. Be aware of the ammo shortage issue.

New 3000 FPS Rimfire Round
A few years back Winchester created a high-velocity 17-caliber rimfire cartridge, the .17 Winchester Super Magnum (aka .17 WSM). Winchester has offered .17 WSM ammo with a choice of three bullet types: 20gr plastic tip (Varmint HV), 25gr plastic tip (Varmint HE), and a 20gr JHP (Super-X). The 20-grain varieties boast a 3000 FPS muzzle velocity, earning honors as the fastest Rimfire ammo ever made.
| .17 Winchester Super Mag Specifications | |||
| Symbol | Sub Brand | Bullet Weight | Muzzle Velocity |
| S17W20 | Varmint HV | 20-gr Plastic Tip | 3,000 fps |
| S17W25 | Varmint HE | 25-gr Plastic Tip | 2,600 fps |
| X17W20 | Super-X | 20-gr JHP | 3,000 fps |
Winchester claims that all .17 WSM ammo types shoot much flatter than the .22 Win Mag and .17 HMR, while delivering 150 percent more energy than both. In addition, the .17 WSM “bucks the wind” better than any other rimfire ammo — exhibiting significant less horizontal drift at extended ranges.

.17 WSM Ammunition is “Unobtanium” Right Now
Since its introduction, .17 WSM ammo has been sold by multiple companies including Browning, Federal (American Eagle), Hornady, and Winchester. Right now it is very hard to find ANY .17 WSM ammo. You have to look far and wide. On January 9, 2022 we checked with five major online vendors and found no .17 WSM ammunition in stock at Midsouth, MidwayUSA, Natchez, Precision Reloading, and Locked&Loaded. Every variety was listed as “Out of Stock” or “Temporarily Unavailable”. That’s discouraging. Hopefully more .17 WSM ammo will be appearing on dealer’s shelves in the months ahead.

Has Savage even released any of these A17 wsm rifles yet? I have been looking for a year and never found one.
