Second shot (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
retake
'second shot' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for retake that I've seen before include "Capture once more" , "Regain possession of" , "back for another shot" , "Sit (an exam) again" , "Further sitting of an exam" .)
