Bob,
You did an excellent job of describing the theory and mechanics. i was just adding some of my experience.
I might also add that I firmly believe the 98 Mauser is still the most reliable bolt-action in every basic way. The pre-'64 Model 70 Winchester (or the M70 Classic) is good but for several reasons doesn't measure up except in peripheral ways, such as the safety and trigger. But the heart of the 98 action is superior, both in extraction and gas handling.
One of the best of the newer CRF actions is the Montana 1999 action. It was designed to combine the best features of the 98 and M70, and pretty much succeeded!
