Value for money, deer hunter's rifle shot? (4,3,4,4)

I believe the answer is:

bang for ones buck

'deer hunter's rifle shot?' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'value for money' is the wordplay.
I cannot really see how this works, but
'money' could be 'buck' (as in a US dollar) and 'buck' is found in the answer.
This explanation may well be incorrect...

I've seen this clue in The Guardian.
