I can't see even slight wear on the bolt handle, or the boss. The back of the bolt has a little flair out, where it rotates on the handle, but I can't imagine that that would make for even a thousandth, I don't know.. Kind of wondering if it ever passed a no-go when it was new. I'll put feeler gauges on it tomorrow, with and without the no-go, and see what it is. Maybe tig a little blob on the handle.
