[QUOTE="ntsqd, post: 1849670, member: 93138"] I think that a one piece bolt should fit tight in battery on an empty chamber, but when not in battery have enough clearance to run smooth and be tolerant of grit. I see a tight fitting case forcing the bolt to be in some certain place as a variable that we don't want. We're asking the case to do something it's really not intended to do. If the bolt is already only able to be in one place while in battery, and then we use a tight fitting case, well that's a different thing entirely. My thinking on this is based on my experience in designing job specific high volume production machine tools rather than specifically firearms experience. The tool (rifle) always guides/clamps/aligns the work (case), the work (case) never, ever guides/clamps/aligns the tool (rifle). [/QUOTE]
