Report from a gun, loaded (8)
I believe the answer is:
bulletin
'report' is the definition.
(bulletin is a kind of report)
'from a gun loaded' is the wordplay.
I cannot really understand how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is found within the answer.
The remaining letters 'bullet' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bulletin that I've seen before include "Broadcast summary of news" , "Official news item" , "Short statement on the news as it happens" , "Short and regular up-date" , "Report for publication or broadcast" .)
