It's risky to go out on this shoot (4)
I believe the answer is:
limb
'this shoot' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for limb that I've seen before include "Eg wing" , "A supporter" , "Human's extension" , "Tentacle" , "Eg, arm, leg" .)
