My first thought was that my scale somehow got messed up, so I found an old ounce scale and the results concurred with what the electronic scale said. although the ounce scale isnt as accurate I could still tell that it was arouund 900-1000 grains once I made the conversion. This is really weird, I have never had weights this high before on either dogwood or hickory arrows. if it was just dogwod or just hickory I might be able to accept that I had found some, insane, ultra-dense wood, but its a mix of both woods.
