Set one's sights (5)
I believe the answer is:
aimed
'set one's sights' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aimed that I've seen before include "Directed towards specified goal" , "Tried; pointed" , "Pointed a weapon at" , "Drew a bead on" , "Set sights on for a dime" .)
