a. Any extraneous occurence, which in the opinion of the referee materially interferes with the equity of the competitor after he calls for his target constitutes a baulk.
b. The sun shall not be considered as an interference. It must be considered as a normal hazard.
c. Under no circumstances will a baulk be granted unless claimed by the competitor immediately it occurs, or if in the opinion of the referee a baulk has occurred, he may restore the competitor's target.

Shooting Rule 1.11b Abide by Result

Should there be a faulty cartridge, misfire or malfunction in the first barrel, in any type of event, and the competitor fires the second barrel where this is possible, the competitor shall abide by the result and shall have no claim to a repeat target for the first barrel.
Where this happens in a points scoring event and the target is broken with the second barrel the decision shall be as follows:
a. - if there was no detonation of either primer or powder with the first barrel the score shall be "1" (3 points)
b. - if there was a detonation of either primer or powder with the first barrel the score shall be "2"(2 points)
In both cases if the target has been missed with the second barrel the score would be "lost'.
