Shot putter? (7)
I believe the answer is:
syringe
'shot putter?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for syringe that I've seen before include "Instrument for injections" , "Means of injection" , "Injector" , "Tube for injections" , "one's prepared for a shot" .)
