Rifle controlled bullet (7)
I believe the answer is:
ransack
'rifle' is the definition.
(synonyms)
'controlled bullet' is the wordplay.
'controlled' becomes 'ran' (I've seen this in another clue).
'bullet' becomes 'sack' (I can't justify this - if you can you should believe this answer much more).
'ran'+'sack'='RANSACK'
Can you help me to learn more?
(Other definitions for ransack that I've seen before include "Rummage, rifle" , "Go through a place causing damage and stealing things" , "Pillage, loot" , "Search (a place) thoroughly" , "Examine thoroughly" .)
