=2. Method of Harmonizing Rifles= (see sky screen, Fig. 58).--(i) The following is the method of harmonizing rifles: The rifles selected for miniature range practices must be numbered from 1 on consecutively. Each rifle must be marked with its number. When this is done, a horizontal line must be drawn along the bottom of the blank sky screen. At intervals of about 12 inches along this horizontal line a number of aiming-marks must be painted. The number of aiming-marks must equal that of the rifles to be harmonized, so that there is one aiming-mark for each rifle. At a distance of 26½ inches above the line of aiming-marks another horizontal line must be drawn on the sky screen, which must be visible from the firing-point. This distance has been chosen because it is sufficient to cause shots aimed at objectives at the bottom of the landscape to clear the top of it and strike the sky screen. (ii) _Harmonizing Rifles for Elevation._--Each rifle will then be adjusted for 1,200 yards. Each rifle, thus sighted, will be fired by a reliable shot with regular aim at one of the aiming-marks. The sights of each rifle will be adjusted until shots which strike above or below the upper horizontal line on the sky screen (when it is sighted for 1,200 yards) strike the line itself. When shots fired from all the rifles strike the line after sights have been adjusted in this manner, they are said to be harmonized. =3. Record of Sighting.=--The variations of each rifle, if any, from the original sighting at 1,200 yards--or 300 yards in the case of sighting for direct hits--will be noted, and its variations written down for reference against the number of the rifle on a board to be hung on the wall of the miniature range. The following is an example of the record of sighting: Twenty-Five Yards Miniature Range. +------+----------------------+-------------------------+ |Rifle.| Elevation for Direct | Elevation for Landscape | | | Hits. | Targets. | | 1 | 300 | 1,200 | | 2 | 300 | 1,200 | | 3 | 350 | 1,250 | | 4 | 250 | 1,150 | +------+----------------------+-------------------------+ VI. SCORING AND SIGNALLING. =1.= When a shot strikes the target so that the circumference of the mark cuts the outer edge of any ring or figure, it is to be counted as hitting within that ring or figure, as the case may be. No shot is to be counted unless the whole or part of the mark of the bullet is seen on the face of the target. A _ricochet_ usually makes a long, ragged hole or mark. =2. Elementary and Figure Targets.=--For scoring in Practice 22, Table B, see Note 2 below.
