Hit, as with snowballs (4)
I believe the answer is:
pelt
'hit as with snowballs' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pelt that I've seen before include "Animal skin with hair still on it" , "Skin; rain hard" , "attack" , "Animal hide" , "16 [CATS AND DOGS]" .)
