Both Hornady and Winnie ammo comes from the same factory for 17WSM. I have a Jard 10/25 which is the 10/22 kind of version rather than their AR type. It uses a roller lock-up on the bolt and runs the Ruger 6 shot rotary mags. Took me ages to tune the extractor, it was leaving the case in the chamber every time until I got that right. The extractor is directly tensioned by a small spring at 90 degrees across the bolt rather than the tidy spring and plunger parallel to the bolt that the Ruger has. The Jard extractor is extremely finicky to install and shape to tune. Once its running, it goes well but fouls quickly. The cases split a lot.
