Some relevant Field Rifle Rules for Competitors
3.2 Rimfire Field Rifles shall have the same specifications as centrefire rifles except that they must be chambered only for the .22LR rimfire cartridge and not weigh more than 4.0 kilograms including: bolt, empty magazine, sights and all accessories except sling (see Section 3.6). Note: Rimfire "Extruder" type barrels are not permitted for use in this class.
3.6 Accessories: In both centrefire and rimfire classes: butt prongs, palm rests, sling stops, adjustable butt plates and adjustable cheek pieces, shall not be permitted.
Note: Rifles fitted with adjustable butt plates or cheek pieces may be used provided these are not re-adjusted during the match.
3.7 Slings: The only aid allowable (which is optional) is a sling, which shall include for purposes of Section 3.1 and 3.2: sling swivels, studs and screws etc. Accessory rails or tracks shall be classed as part of the rifle and therefore subject to the weigh in. The sling shall not be wider than 70 mm. (2-3/4 inches) at any point except the buckles or such devices as are used to regulate its length. If a sling is used, it must be fastened to the stock at two points, the fore-end attachment must be forward of the front of the action and the rear attachment must be a minimum of 100 mm behind the centre point of the face of the trigger blade. Triggers with adjustable blades are to be measured from the rear most position. A sling may be adjusted but not added to or removed from a rifle once a match has commenced. Whelen slings and those used in this manner, double arm slings and similar devices are specifically excluded. Slings that are specifically moulded are also excluded.
4.4 Coats: Commercial type trap and skeet vests and shotgun shooting shirts are permitted as well as clothing normally suitable for existing climatic conditions. Shooting coats, unnecessarily heavy clothing or anything on the person that would provide artificial support or change in rifle balance (except as approved in Section 4.6) such as clothing having excess padding or stiffening material or which restricts or supports the body in the shooting position shall not be worn.
8.6 Ammunition: Only the exact number of rounds relevant to the course of fire for each position is to be taken to the firing line. A round may not be exchanged for another except as outlined in Section 8.13 and 8.16, or if a round is accidentally damaged before being loaded into the firearm to the extent that the round, if fired, may be unsafe or cause damage to the firearm. This exchange must be supervised by the Range Officer.
8.8 Rapid Fire starting position and procedure: Before each burst of rapid fire, the Range Officer shall make certain that each competitor loads 3 rounds into their magazine (if a magazine rifle), that the breech is open, and that the muzzle of the rifle is pointed up range. The rifle is to be held in both hands, with the butt stock at waist level and visible below the elbow.
8.9 Rapid Fire timing and commands: The Range Officer will then ask "Is any shooter not ready?" and if there is no reply within 3 seconds, will then give the command, "COMMENCE FIRE". The command is to be given with a one second delay between the words. The commencement of the timing (shooting) is to be taken from the word "FIRE" and checked with a stop watch for the expiration of 15 seconds.
The rifle must remain in the start position and the bolt is not to be closed until the word “FIRE”.
The "CEASE FIRE" command is to be given in a similar manner with the word "CEASE" to start at the 14 second mark, and the word "FIRE" to be given exactly on the 15 second mark. The word "FIRE" being the operative word in each command.
SECTION 13: SCORING, PENALTIES, CROSS FIRES, EXTRA SHOTS ETC.
13.1.1 Scoring: A maximum of 5 shots will be scored on any one target. Targets are to be scored in the usual manner: i.e. a hit that touches a scoring ring shall be given the higher value if a gauge of the same calibre as that used to fire on the target, touches some part of the ring when the gauge is inserted in the bullet hole, or an overlay scoring slide of the same calibre as that used to fire on the target touches some part of the scoring ring when the slide is laid on the target. A round that is found to have "tumbled" will be scored in the usual manner (best edge) if any part of the shot touches the scoring ring then it will be given that value. A tumbled round cannot be gauged.
13.1.2 Rapid-Fire: In the standing unsupported rapid fire position, 12 shots in 4 bursts of 3 shots are fired on two targets (6 shots on each) for a full match. On those targets on which no more than 6 shots are present, the 5 highest valued shots are to be scored.
Note: Section 13.4.
13.1.3 Slow-Fire: In the three slow fire positions, 5 shots are to be fired on each of two targets in each position, all of which shall be scored.
13.2 Cross-fires onto another competitor's target: A competitor firing on another competitor's target shall lose all the shots cross-fired. The competitor, whose target has been cross-fired on, shall not receive the benefit of the cross-fired shot when this can be identified. If the cross-fired shot cannot be identified, it is assumed to be the lowest valued shot on the target.
13.3 Extra Shots: Where a competitor has fired more than the permitted number of shots for a particular position in a full match, the highest valued shots will be struck out from targets on which more than 5 shots (6 for rapid fire) have been fired until only the number of shots required for that position remain. If an extra shot or shots have been fired at another competitor's target, then the highest scoring shot fired in that position will be struck from the offender's targets for each infringement.
13.4 Self Cross-Fires: Where a competitor fires no more than the permitted number of shots for a particular position in a full match, but places more than 6 shots for rapid fire, or 5 shots for any of the other positions on one target, and the balance of the shots, or no shots at all on the other target then no more than the 5 highest scoring shots on the target with the excess shots are to be scored. The only exception to this rule is when shot disbursement is 7-5 in rapid fire. In this one case, the highest and lowest valued shots will be struck from the target with 7 shots and the remaining 5 scored. All 5 shots will be scored on the card with 5 shots.
