Snooker shot from one of the big guns? (6)
I believe the answer is:
cannon
This could be a double definition.
'snooker shot' is the first definition.
(I've seen this before)
'one of the big guns?' is the second definition.
'cannon' can be an answer for 'guns?' (I have seen 'Wheeled guns ' mean 'cannon' so perhaps 'guns' could also mean 'cannon'). I'm unsure of the 'one of the big' bit.
'from' is the link.
Can you help me to learn more?
(Other definitions for cannon that I've seen before include "Great gun" , "mortar" , "Old naval gun" , "Large wheeled gun" , "Large gun mounted on wheels" .)
