3. Loading, Firing, Timing, and Cleaning.—In all revolver and pistol matches the weapon must not be loaded until the competitor has taken his position at the firing point. The barrel must always be kept vertical or pointed towards the target. After the target is in position and a match or record score has been begun, in case of an accidental discharge or of defective ammunition, if the bullet comes out of the barrel it will be scored a shot. The timing in matches C, D, E, and F will be as follows: The competitor standing at the firing point with the arm loaded, not cocked, and the barrel pointing in a direction not less than 45 degrees from the target, will signify to the scorer when he is ready to begin each string. The scorer, stop watch in hand, will then give the command, “Fire,” after which the competitor may cock and aim his weapon and shoot his string. At the expiration of the time limit the scorer will announce “Time.” Misfires will be scored zero, only in Matches C, D, E, and F. Competitors may clean weapons in Matches A and B, and in the corresponding Indoor Championships, but no time allowance will be given for time spent in this way. All competitors will be required to finish their scores within the time limits specified, except in cases of accident, when the time may be extended at the discretion of the executive committee. Blowing through the barrel, to moisten it, will be considered cleaning.
In revolver matches the arm must not be used as a single loader or loaded so as to use a limited number of chambers in the cylinder. The cylinder must be charged with the full number of rounds for which it is chambered, and these must be shot consecutively. If scores are shot in ten shot strings, the cylinder shall be charged first with six rounds and then with four rounds. If the cylinder only contains five chambers, then the ten-shot strings may be shot in two strings of five each. In Matches C, D, E, and F and indoor or gallery events, the arm shall in all cases be charged with five rounds.
4. Position.—The position shall be standing, free from any support, the pistol or revolver being held in one hand, with arm extended, so as to be free from the body.
