Elevation: Enter any elevation change applied to the rifle under that numbered shot.
Windage: Enter any windage used (in click si under that numbered shot. Count left or right from actual zero not mechanical zero. (c) After firing.
Wind: Word description (steady, gusty, fish tailing I.
Light: Word description (bright, dull, hazy, overcast).
Mirage: Word description (medium, heavy) and/or a simple picture (fig 149).
Windage diagram: Velocity in kmph and show direction with an arrow.
Light diagram: Show direction with an arrow (arrow should point in direction the firer's shadow is cast when he is facing the target!.
Sight picture: Show the position of the front sight in relation to target for that group of shots.
Remarks: Make a note of any equipment, performance, weather conditions, or range conditions that had a good or bad effect on the firing results.
Elevation zero: That elevation in minutes that is correct for this position and distance.
Windage Zero: The number of clicks left or right of mechanical zero that is correct under no wind conditions for this position and range.
(4) The record data sheet should be analyzed bv the individual at the completion of firing from each position and range and again at the end of each day's firing. Some of the things to look for when analyzing the data sheet are:
/¿^Compare hits to calls; if they agree it's a good indication that zero is correct and any compensation for the effects of weather was correct. If the calls and hits are consistently out of the target, sight adjustment or more position and trigger control work are necessary. Comparisons of the weather condition and location of the groups on the latest data sheet with previous data sheets aid in determining how much and in which direction the sights should be moved to compensate for the various weather conditions. If better results are obtained with a different sight picture under an unusual light condition, then the firer should use this sight picture whenever firing under that particular light condition. A different sight picture may necessitate adjusting the sights. After establishing how much to compensate for the effects of weather, or which sight picture works best under various light conditions, the firer should commit this information to memory.
(b) The firing data sheets used for training or zeroing should be kept for future reference. Rather than carry the firing data sheets during training, exercise, or combat, a list of the elevation and windage zeroes at various ranges can be carried by the individual in his pocket or taped on the weapon stock.
