Shucking targets (4)
I believe the answer is:
ears
'shucking targets' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ears that I've seen before include "Auricles" , "'''Friends, Romans, countrymen, lend me your ...'' (Julius Caesar) (4)'" , "Walls are said to have them" , "Organs of hearing" , "Spikes of corn" .)
