Snap "Try!" (4)
I believe the answer is:
shot
This clue is a double definition.
'snap' is the first definition.
(thesaurus)
'try' is the second definition.
(shot is a kind of try)
(Other definitions for shot that I've seen before include "Slug" , "Snap" , "description of some silk" , "Sound of gun" , "streaked with colour" .)
