Having an issue with a new rifle - blueprinted rem 700 action, ptg bolt and timney trigger. Have put about 100 rounds thru it and it has shot great. Went to the range this week to shoot. Loaded first round and nothing. Trigger would not pull. Nothing. Like it was locked. Went home and pulled action out of stock and the trigger was like it was locked in safe. moved the safety switch, cycled the bolt, hit everything with a little lube and got the gun to cycle and trigger worked. Not sure what I did to make it happen. Put action back into stock and cycled the bolt and dry fired and everything looked good. Went to the rage next day. First 5 rounds, pin would hit primer but would not fire. These were reloads. Tried a couple of factory loads and same thing, mark on primer but no fire. Tried a few more and one finally fired. Shot about 20 rounds that fired and had one of two more that would not. Got home, took bolt apart and cleaned it. Took a lot of effort to pull back the tab to spin off the firing pin. Put back together and tried a few once fired brass with new primers. Had 3 fire then the next 8 marked the primer but did not fire. Not bolt is acting even worse. Dry fire and the firing fin moves a little slow with muffled click. Recock and dry fire again and firing pin moves in slow motion with no click. I had put 100 rounds thru this new rifle without incident and now this. I have a hunt coming up and need to sort this out so I know that when I need to shoot that the gun will fire. Any ideas?
