Steve,
Yeah, the first Stiller action the gunsmith I mentioned bought was good to go. So he bought several more, and the majority weren't.
This may be gungack rumor only but what I heard was the problems arose when they first started farming out the bolts to PT&G. The specs between bolt and receiver were not what they should have been. This lasted less than a year before PT&G got it resolved.
This can happen easily if two different machining operations are done separately with out custom matching each bolt and receiver.
This is also a reason for heat treating prior to final machining. Most of the good ones are done this way.
