Bound to be a time for shooting (6)
I believe the answer is:
spring
'bound' is the definition.
(both can mean to leap)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for spring that I've seen before include "Vivaldi's work, in order(6;6;6;6)" , "Spa" , "new dawn?" , "Leap - part of year" , "The bouncy season" .)
