Very odd rifle, not really for battle (9)
I believe the answer is:
solferino
'for battle' is the definition.
(Solferino is an example)
'very odd rifle not' is the wordplay.
'very' becomes 'so' (I've seen this in other clues).
'odd' indicates anagramming the letters.
'not' becomes 'no' (I've seen this in other clues).
'rifle' anagrammed gives 'lferi'.
'so'+'lferi'+'no'='SOLFERINO'
'really' acts as a link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for solferino that I've seen before include "reddish colour" , "1859 battle" .)
