the easiest way to dowel that is with a match... just jam it in the hole and break it off.
It is, but not advisable when the new hole is very close or overlapping the old - then sometimes the screw will still pull into the old hole. The best way to do it is to drill out the old hole to get rid of the taper and clean it up, and then tap in a proper dowel of the right diameter with some cold glue to fix it in place and fill any voids.
