Consequence of firing in the air? (6)
I believe the answer is:
upshot
'consequence' is the definition.
(synonyms)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for upshot that I've seen before include "Event" , "One killed the albatross" , "Outcome, final result" , "Eventual outcome or conclusion" , "issue" .)
