Below is the Cadets and Schools 25 yard target as used in the Miniature Winter League - Veteran Class. Two shots are put on each diagram. The 15 yard target is the same layout of five diagrams, but inverted, with two at the top and three at the bottom. The diameter of the black on this target is 1.84 inches at 25 yards and 1.17 inches at 15 yards The inward gauging OUTSIDE diameters of the bull for 25 and 15 yards respectively are 0.380 inches and 0.105. inches. On these inward gauging targets, moving inwards, each white scoring line must be touched or broken into to score the higher figure. (see comparative scaling notes below for 20 yards)
The 25 yard card has five diagrams, as the Cadets & Schools, and again two shots are put on each diagram. The diameter of the black on this target is 1.54 inches at 25 yards and 0.84 inches at 15 yards. The inward gauging OUTSIDE diameters of the bull for 25 and 15 yards respectively are 0.380 inches and 0.105. inches. Note that there is an X-ring or "Carton" only on the 25 yard target. (see comparative scaling notes below for 20 yards)
The details for its use are on the League information page The dimensions of the black on this target are 1.06 x 0.72 inches at 25 yards and 0.67 x 0.47 inches at 15 yards (see comparative scaling notes below for 20 yards)
The "deliberate" card for the Post-Veteran class is the familiar and current 1989 N.S.R.A. target shown below. The diameter of the black on this target is 2.05 inches at 25 yards and 1.23 inches at 15 yards The outward gauging INSIDE diameters of the bull for 25 and 15 yards respectively are 0.496 inches and 0.965 inches. Moving outwrads, each white scoring line requires to be broken through to the next lowest scoring ring black before the lower figure is scored. (see comparative scaling notes below for 20 yards)
Below are the American decimal TARGETS used in the Dorchester Rifle and Pistol Club's 50 yard Summer League
and all Winter Standing League classes from October 2001 The diameter of the black on both American targets shown below is 3.875 inches for use at 25 yards offhand (standing) and 50 yards prone. The inside diameter of the bull (not the X-ring or "Carton") is 0.9 inches. (see comparative scaling notes below for 20 yards)
The formula for scaling targets is new size = distance ratio (radius + 0.11) - 0.11 where r = original radius to be reduced or increased, and 0.11 is half the diameter of a .22 bullet. For example, to reduce the a diameter from 25 yards to 20 yards range ~ diameter "x", where the original diameter at 25 yards is 3.875 inches, making its radius half that at 1.9375 inches. Divide 20 by 25 = 4/5 Therefore "x" = 2 x new radius = 2 x 4/5 (1.9375 + 0.11) -0.11 = 3.056 inches
