Depending on the cadet & the specific rifle sight, 3 - 5 clicks equates very approximately to the width of the scoring rings.
We have one rifle that had full right sight adjustment applied - no opportunity to move any more to the right if a firer held a group left of the bull. Not used since back from recent servicing at BSA, hopefully the sight was tweaked.
Big surprise when we zeroed them for 10m (Regional competition), I had to wind DOWN several handfuls!
