A blow within faction, journalist getting shot (10)

I believe the answer is:

catapulted

'shot' is the definition.
(shot with a catapult)

'a blow within faction journalist' is the wordplay.
'blow' becomes 'tap' (tap is a kind of blow).
'within' indicates putting letters inside.
'faction' becomes 'cult' (religious faction).
'journalist' becomes 'ed' (short for editor).
'a'+'tap'='atap'
'atap' put inside 'cult' is 'catapult'.
'catapult'+'ed'='CATAPULTED'

'getting' acts as a link.

I've seen this clue in The Guardian.
