a. Voluntary abandonment of the shoot, in which case his score to that point will be presented as a valid result.
b. To affect a repair to equipment that has been rendered unsafe or incapable of firing a shot by whatever means. This does not include zero-shift of optical equipment or poorly zeroed systems.
(Rule 15 b. is NOT applicable when a shot-gun start is employed; in this circumstance please see shooting Rule 17 - FIRING LINE CONDUCT)
c. For any other occurrence deemed valid by the Chief Marshal or Deputy.
Note: In Rule 15 b, the competitor may replace the offending part or equipment with the permission of the Chief Marshal or Deputy.

(Unless the Chief Marshal grants specific permission).
In all the above cases the competitorís scorecard must be handed to the Chief Marshal or Deputy and his/her permission obtained to leave the firing line, with a stipulated time for return. The card will be marked with the time of departure. Any card not claimed within the designated time will be submitted for scoring.
