Two Measures of Scale. The size of a miniature, relative to what it is a replica of, is known as the scale of the figure. For no particularly good reason, two different systems are used to rate scale. Some scales are given as a ratio, variously written as either a ratio (i.e., 1:300 or 1.300) or a fraction (i.e., 1/300).
In terms of target angles, the size of a typical reticle line is roughly 0.1 MOA, and the size of a reticle dot is 0.125 MOA (fine target dot) to 0.9 MOA (USMC mildot). The vital zone diameter is about 8 inches on most big game. At a range of 1,000 yds, an 8 inch diameter subtends 0.80 MOA.
