Throwing poor actor out of former county town (7)

I believe the answer is:

bucking

'throwing' is the definition.

'poor actor out of former county town' is the wordplay.
'poor actor' becomes 'ham' (I've seen this before).
'out of' indicates named letters should be taken away.
'former county town' becomes 'buckingham'.
'buckingham' with 'ham' taken away is 'BUCKING'.

I've seen this clue in The Telegraph.
