Gun with zero plastic (8)

Ross

I believe the answer is:

howitzer

'gun' is the definition.
(howitzer is a kind of gun)

'with zero plastic' is the wordplay.
'plastic' is an anagram indicator (plastic can mean easily moulded).
'with'+'zero'='withzero'
'withzero' is an anagram of 'HOWITZER'.

(Other definitions for howitzer that I've seen before include "High angle gun with a short barrel" , "Trench mortar" , "Military weapon" , "Gun firing shells at a steep angle" , "Cannon with a steep firing angle" .)

I've seen this clue in The Times.
