Ramage Heading Back To The Premiership?
The Tykes went into the lead thanks to Iain Hume's fifth-minute effort as the visitors dominated the early stages at Loftus Road.
But QPR hit back with Hall latching on to two set-pieces to put his side in control at the interval.
Hall should have completed his hat-trick but he failed to beat visiting goalkeeper Luke Steele with his second-half penalty.
Peter Ramage, Kaspars Gorkss, Lee Cook, and on-loan Real Madrid youngster Daniel Parejo were all also handed full debuts by QPR boss Iain Dowie.
