Report covered Romeo's crude weapon (9) ?O?M?R?N?

Now, I make it BOOMERANG - the 'OOMER' being an anagram of 'ROMEO'. But don't understand how 'Report=BANG'

[excelsior]

you will find 'bang' and 'report' can both be used as synonyms for each other

[Catron]

Thanks to both of you. I have never come across such a use in cryptic crosswords before.
