My Ruger Mark III hunter in stainless runs flawlessly. It's my steel Challenge gun. I've seen issues with the 22/45's as well on the steel challenge ranges.
It's just the rifles giving me fits. Running full stock currently. Expect that to change. Can't handle a gun that won't run.
Dennis you might look at getting a Kidd or Volquarten bolt. But my experience has been that a lot of problems with the 10/22 is the factory recoil spring and lever. Kidd sells a 2 piece design that comes with 3 different recoil springs for the ammo you are using and that upgrade has always made a huge difference in cycling problems.
