Go out with a bang (6)
I believe the answer is:
strike
I believe this clue is a double definition.
'go out' is the first definition.
(thesaurus)
'bang' is the second definition.
(I know that bang can be written as strike)
'with a' is the link.
(Other definitions for strike that I've seen before include "Sudden success" , "Hit the labour withdrawal" , "Hit; withhold labour" , "Song of regret" , "Hit forcibly" .)
