I looked at a few manuals and found you were probably about a grain over book. Not much, but I added the required warning the OP. If you know a published source with that load, I can pull it back out again.

It strikes me as odd the change did little to the stickiness. If you load the same brass down to, say 27.1 grains (the nearest bullet weight Sierra max) does it stop? If not, I'd be suspicious, as you are, the bolt has an issue or some debris got into it. Otherwise, I'd be looking for drag marks. Did you find any on the case head?
