Peas for shooter? (4)
I believe the answer is:
ammo
This clue could be a double definition.
'peas for' is the first definition.
The definition suggests a singular noun which matches the answer.
'shooter?' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
Can you help me to learn more?
(Other definitions for ammo that I've seen before include "Bullets (sl.)" , "Projectiles" , "essential supplies for soldiers" , "arms" , "eg Bullets, shells" .)
