No firearm may be decocked on the firing line to avoid a penalty if cocked at the
wrong time, position or location once a round has gone downrange. Once a
revolver is cocked, the round must be expended (shot). However, if a round has
not gone downrange, and under the direction and supervision of the TO, the
revolver may be decocked. This requires a positive indication/acknowledgement
from the TO for the shooter to do so. (See also “Double Jeopardy” avoidance in
Safety & Handling Conventions – All Firearms)
