Skin – bombard (4)
I believe the answer is:
pelt
I believe this clue is a double definition.
'skin' is the first definition.
(an animal's skin)
'bombard' is the second definition.
(I know that bombard can be written as pelt)
(Other definitions for pelt that I've seen before include "Throw - animal skin" , "Skin, hide" , "fall hard" , "Hide; rain" , "Subject to bombardment" .)
