Is it using oil? Smoking?
Is the compression pressure low?
If so, I'd change to dinosaur oil until the above conditions change.
Actually, most rings today are chrome moly, and they seat pretty damned
fast. Most of the seatingin is finished within a few hundred miles,
although peak sealing my not arrive until around 5-10,000 miles.
Most manufacturers recommend using convention oil for breakin, as you
obviously know.
One thing that will speed ring seating is heat, as in get the motor up to
230-240-degrees. Proceed with caution, obviously.
