Took it to the range today to re-sight in the scope. I noticed that, roughly a third of the time, the trigger pull resulted in a miss-fire, the same thing that happens when you pull the trigger a second time without opening the action. The hammer falls and bounces. I'm assuming that there is something going on that involves the reset feature. I've never taken it apart and it is the only one I have.
I don't think it matters but, for what it's worth, is is the Katadin model.
I just got home with it. I hope you say to clean the action, but I'm afraid there may be more involved than that.
