Mike,
A spacing washer in the rim recess seems like an elegant way to solve the headspace problem without additional changes to the original rifle.
The washer is about .005" too thick and I'll use the chambering reamer to set the final headspace, so it will be awhile before this story is complete.
Feel free to PM me if you have any questions that don't fit with this thread.
