A bolt possibly shot (5)
I believe the answer is:
arrow
I believe this is a double definition.
'a bolt' is the first definition.
(I've seen this in another clue)
'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" .)
