Bold action going wrong, restricted by strange uprising (7-2)
I believe the answer is:
derring-do
'bold action' is the definition.
'going wrong restricted by strange uprising' is the subsidiary indication.
'going wrong' becomes 'erring' (I've seen this before).
'restricted by' is an insertion indicator (I've seen this in other clues).
'strange' becomes 'odd' (I've seen this before).
'uprising' is a reversal indicator.
'odd' in reverse letter order is 'ddo'.
'erring' put into 'ddo' is 'derringdo'.
(Other definitions for derring-do that I've seen before include "Brave acts" , "Daring deeds" , "'bold action'" , "heroic deeds" , "Courageous action" .)
