Narrative:
On the linkk arrival we noticed we were following a heavy 747 and discussed staying a safe distance behind that aircraft for wake turbulence considerations. Upon reaching the final controller our separation had been reported to us as six miles. A visual approach was flown by hand so we could remain safely above the ILS glideslope as a reference for potential wake turbulence. At approximately 300 feet we experienced a wing drop and a go around was executed.calm winds and a close approach following a heavy aircraft resulted in an unstable approach.ATC separation minimums for aircraft the size of an E-135 following a heavy are in my opinion insufficient. I would recommend additional weight categories and/or increased separation distances.
