DEFIANCE ACTIONS MANUAL

On actions with the one thread of relief cut, I'll make a relief cut on the barrel to prevent the thread from interfering with the barrel shouldering up and the threads centering. Going in and cutting a relief cut on the barrel made a barrel that wouldn't shoot go to shooting. I've seen that cause problems as the barrel seems to tighten correctly, but don't. The Surgeon actions have the same thing, one thread of relief cut.

DEFIANCE ACTIONS MANUAL

When you are cutting threads on a manual machine, two threads of relief lets you not have to cut as close to the shoulder when pulling out of the barrel thread. The only thing I would change on them is to have two threads of relief cut at the front of the action instead of the one they have. I looked at the action specs that I had recorded from the custom actions that I had barreled and the few Defiance actions that I had barreled were 1 1/16'-16 threads. One thing they do have that I like is more extraction camming than the action Glenn made when he was in Poulsbo and later Sturgis. I'll look tomorrow and see if I had the thread specs recorded on a Defiance benchrest action. I've done some Defiance actions that had coned bolts, but don't remember what they were, but would figure that they were 1 1/16-18 threads.
