Rifle controlled bullet (7)

Ross

I believe the answer is:

ransack

I'm a little stuck... Click here to teach me more about this clue!

'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" .)
