Have been working up loads for my White Tail hunt in two weeks and today when using the set trigger the rifle would not drop the hammer.resetting did not produce results. The trigger would just pull back, go click, but no hammer drop. Took it apart looked and put it back together. Put a rag on the nipple went thru the motions and would woork as intended. Loaded it up, stepped up to fire and would not drop the hammer. Took it all apart, cleaned with One Shot, blew it out with air and lubed with Rem oil. Will try again tomorrow. Any ideas?
