It sounds like the firing pin is dropping when you close the bolt as the trigger is not resetting.

I'd take the action off the stock and give the trigger assy a good flush with lighter fluid and blow out with compressed air. That may well fix your problem. Over time lube and dirt accumulate in various places like the trigger assembly. Some lubes, when they age, become like a sticky glue that keeps small pieces from moving as they should. Remember, trigger springs are purposely light so you don't have to use two fingers to pull the trigger.

As for re-lubing the trigger, I prefer nothing more than a drop of CLP, Gun Butter, or 3-N-1 oil right on the sear itself. Nowhere else. There is so little movement and the parts are hardened so wear is not a real issue in a trigger.
