Narrative:

After climbing through 18000 ft I should have set my altimeter to 29.92. As a result when I reached my final altitude of 19000 ft, I was contacted by ZJX telling me to reset my altimeter and, that I was about 350 ft low. At this point I reset to 29.92 and climbed to the instructed and actual altitude of 19000 ft. As this was my 4TH high altitude trip, I did not remember soon enough to do this.
