| Patent 5960576: Range, bullet drop, and angle calculator for use with telescopic gun sights (12435 words) |
 | Thus, the drop chart 33 serves as a means, preferably on the second rule member 30, for determining a bullet drop value for the previously determined known distance. |
| The user refers to the drop chart 33, but applies the corrected range of 230 yards to the drop chart 33 to determine the proper bullet drop value to be utilized in further calculation of the elevation adjustment. |
| The elevation scale(s) and bullet drop scale, and/or the mildot scale and the target dimension scale, likewise may be switched between the respective rule members without departing from the spirit of the invention, and it is intended to cover in the appended claims such equivalent embodiments. |
