Pint-Sized Power — the 3000 FPS 17 Win Super Mag Rimfire
At SHOT Show 2017, we had the chance to chat extensively with Eric Mayer, head honcho of Varminter.com. An avid shooter and hunter, Eric loves small, efficient cartridges. Eric told us his current favorite rimfire cartridge is the 17 WSM. “Winchester has continued to improve this cartridge since its introduction. We are seeing very good accuracy now, and performance is impressive in the varmint fields”. Eric notes that the 3000 fps 17 WSM 20-grain ammo (photo above) delivers way more punch downrange than a typical 17 HMR load. In this article, you’ll find the highlights of Varminter.com’s review of the 17 WSM round in the Ruger 77/17 cartridge.
The 17 Winchester Super Magnum Rimfire (aka Win Super Mag or WSM) is the fastest, most potent modern rimfire round you can buy. This cartridge, which uses a modified nail gun casing, drives 20gr bullets at 3000 fps. The 17 WSM offers superior ballistics to all .22 rimfires, and is a clear step ahead of the 17 HMR. That makes this round a potential “game-changer” in the varmint fields. To gauge the capabilities of the 17 WSM, Varminter.com tested the cartridge in the new Ruger 77/17 bolt-action rifle.

17 WSM shoots faster than the 17 HMR, so the 20gr bullets don’t drift as much in the wind:
Varminter.com reports: “The much-anticipated Ruger 77/17 chambered in the 17 Winchester Super Magnum (17WSM) has been released. Our Review Editor, William Chambers, put it through a full range test with all four currently-available ammunition loads. Afterwards, he took it on a short groundhog hunt[.] We put a lot of rounds through the guns we test, at targets, through chronographs and out in the field. This report includes all currently available 17 WSM ammunition and a sneak peek of the really nice Nikon Prostaff 5 riflescope.” READ REVIEW.
As part of its review, Varminter.com tested four different types of 17 WSM ammo for accuracy: American Eagle (20gr V-Max); Hornady (20gr V-Max), Winchester HV (20gr V-Max); Winchester HE (25gr V-Max). In the little Ruger, which suffered from a very heavy trigger, the most accurate ammo, by far, was the American Eagle, with an average 5-shot group size of 1.135 MOA at 100 yards. The Winchester HV was the worst, with a 2.304 MOA average for three, 5-shot groups. CLICK HERE for full accuracy test results.
After accuracy testing, Varminter.com Review Editor Chambers took the Ruger 77/17 on a Groundhog hunt in Northern Ohio. Chambers was successful, bagging this ‘hog’ at 127 yards. The American Eagle 17 WSM ammo did quick work — the groundhog dropped without a twitch (watch video).
