Trapshooting (5)
I believe the answer is:
skeet
'trapshooting' is the definition.
(I know that trapshooting can be written as skeet)
This is the entire clue.
(Other definitions for skeet that I've seen before include "American clay pigeon shooting" , "Form of clay pigeon shooting" , "US version of a shooting sport involving clay pigeons" , "A form of clay-pigeon shooting" .)
