A bolt possibly shot (5)
I believe the answer is:
arrow
I believe this clue is a double definition.
'a bolt' is the first definition.
(thesaurus)
'shot' is the second definition.
(thesaurus)
'possibly' is the link.
(Other definitions for arrow that I've seen before include "Item in a quiver" , "Direction indicator" , "Fletcher's production" , "Indicator; missile" , "Arm" .)
