Carrying note, is poor delivery able to get one fired (10)
I believe the answer is:
cannonball
'carrying note is poor' is the definition.
I can't judge whether this definition defines the answer.
'delivery able to get one fired' is the wordplay.
I cannot really see how this works, but
'delivery' could be 'ball' (delivery in cricket) and 'ball' is found within the answer.
'able' could be 'can' and 'can' is located in the answer.
The remaining letters 'non' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for cannonball that I've seen before include "Big shot" , "Battlefield projectile" , "one fired long ago" , "Old projectile" .)
