Narrative:

After leveloff at FL310 near hancock VOR (hnk) in ZBW's airspace. I was reported to be 300 ft low in altitude. I had failed to set 29.92 inches from 30.19 inches passing FL180. I had made one short (1-2 min) intermediate leveloff at FL280. I reset the altimeter and made the altitude adjustment. Lesson learned.
