Approximately 1 in 20 getting stuck in the chamber and then the frustration of feeding the next round onto a stuck cartridge case.
I'm also not overly happy with the accuracy, 2" grouping at 50m from a bench and bi-pod and the occasional flier.
What ammo should I try and should I return the rifle to have the extractor checked.
I wouldn't do anything until you try some different types of ammo. Winchester doesn't shoot well for me in anything. The 42gn SubMax is a decent one if you have to use Winchester, but try CCI Standard Velocity and Velocitor, and some Eley Subsonic and Match. Federal F510 generally shoots fairly well, along with SK Rifle Match. Try as much variety as you can find and you should find something able to group around 15mm at 50m.
Make sure the extractor and spring are clean, as well as the extractor groove in the breech face, and the chamber itself.
