The action I received has 1/8" of free take up at the bolt handle before the lever does its magic and that only retracts the bolt ~0.031" and more than half of that is given away under the extractor.

Does this mean that you've had problems with extraction?
I can follow the math, but I don't know from experience how much extraction is necessary to pull a case from a chamber. I would assume there was some testing done prior to production or they would have adjusted the load point of the lever closer to the beginning of its motion. I would think that the 1/8" of free movement prior to it striking the load would potentially increase the force exerted on the leverage side of the fulcrum by creating some inertia prior to making contact. I'm certainly interested in hearing if anyone has issues with extraction though. That was one of the selling points of the action.
