Sons of a gun shot grouse (6)
I believe the answer is:
rogues
'sons of a gun' is the definition.
The answer and definition can be both people as well as being plural nouns.
Maybe you can see an association between them that I don't see?
'shot grouse' is the wordplay.
'shot' is an anagram indicator.
'grouse' with letters rearranged gives 'ROGUES'.
Can you help me to learn more?
(Other definitions for rogues that I've seen before include "'Scoundrels, charlatans (6)'" , "Wild animals driven away from the herd" , "Varlets" , "Rascals" , "Scoundrels, miscreants" .)
