checked again in order to establish whether the error lies with the operator and his<br />

setting of the sights or the position of the machinegun in the firing emplacement. After<br />

this, the firing is repeated. If no satisfactory results are achieved, the machinegun is<br />

sent in for inspection and repair.<br />

If the results achieved with automatic fire are satisfactory (CS not more than 5 cm<br />

away), the pattern of shots is copied from the target onto a piece of paper on the scale<br />

1:5. The number of the machinegun, date, time, temperature, and height above sealevel<br />

are recorded on the copy of the target, which is signed by the range officer-incharge.<br />

This data is submitted along with the technical manual of the machinegun to be<br />

consulted whenever information on precision and accuracy is required.<br />

Tripod Automatic Fire Zero.<br />

• Zeroing the weapon is conducted by firing 10 x ball ammunition cartridges from the<br />

same lot of ammunition. Fire is conducted in one 10-shot burst.<br />

• The weapon is zeroed on a firing range at 100 meters with the rear sight setting at<br />

‘3’ and the sight bar division remains on the adjusted sight settings.<br />

• The position for firing is prone, tripod supported. The traversal and elevation<br />

mechanism has to be set, and the stock supported on the shoulder.<br />

Automatic fire zero standards. The machinegun is considered sufficiently precise and<br />

accurate if 8 out of 10 shots fall within the 20-cm-radius ring, and the CS is not more<br />

than 5 cm away from the CP. Shots that touch the ring on the outside are also<br />

considered valid. The firing can be repeated two or three times, and if no satisfactory<br />

results are achieved, the machinegun is sent it for repair.<br />

If the machinegun is not precise enough and the CS falls more than one mil (0-01) from<br />

the CP, the distance between the CS and the CP is measured both horizontally and<br />

vertically. The resulting deviation in divisions of the rear sight and the deflection<br />

correction is recorded in the documentation and taken into consideration during tripod<br />

firing.<br />
