Really hate to point this out but even Jerry has problems with the 617 10 shot. Count the shots in his run of 10 22 shorts in the video and watch the hammer 10 pulls 9 shots. Getting the mechanical timing for 10 shots DA in a K frame is a nightmare. I had 3 so far, 1 early six shot, 1 10shot alloy and a basic 617 10 shot and both 10 shots had the same issue with missed firing pin strikes if you shot fast. Great single action though.
