I heard and fired in range (7)
I believe the answer is:
eyeshot
'range' is the definition.
(eyeshot is a kind of range)
'i heard and fired' is the wordplay.
'heard' indicates a 'sounds like' (homophone) clue.
'and' is a charade indicator (letters next to each other).
'fired' becomes 'shot' (shooting is a kind of firing).
'i' is a homophone of 'eye'.
'eye'+'shot'='EYESHOT'
'in' is the link.
(Other definitions for eyeshot that I've seen before include "Range of sight" , "Distance for which one can see" , "View" , "as far as one can see" , "Range of vision" .)
