Abstract
A method for the evaluation of the pattern of shot resulting from a single shotgun round for purposes of optimizing the selection of ammunition type and prediction of shot pattern, and a target for its implementation. The shooter fires a single round at the target. Then a rotating overlay allows the pattern of shot to be evaluated with respect to a center aim point and an overlay axis and kill zone. The overlay is rotated through a series of clockwise, then counterclockwise increments. At each increment, the target is scored with respect to the overlay. The number of shot striking the kill zone for each position of the overlay axis is computed and by observation the shooter can determine the optimal ammunition for use with the weapon and for a given type of game.
Claims2
A target for use in evaluating the shot spread and pattern for a shotgun, to optimize the selection of ammunition, comprising:
- a. a rectangular target background;
- b. a circle circumscribed within said rectangular target background, said circle having a center aiming point, a periphery, and a diagonal line as a fixed vertical axis;
- c. a multitude of regularly spaced radii propagating from said center aiming point outward to and intersecting with said circle periphery;
- d. a multitude of scoring areas, in a number corresponding to the multitude of regularly spaced radii, each of said scoring areas being located outside and adjacent to said periphery at a respective point of intersection of said radii with said periphery;
- e. a multitude of concentric, smaller circles within said circle and focused about said center aiming point each having a small circle periphery whereby the relative distance of said smaller circle periphery from said center aiming point is usable for measuring;
- f. a game animal picture in frontal view imposed upon said center aiming point and having a kill zone comprising the game animal head area, game animal neck area and game animal breast area;
- g. a transparent overlay having a center of rotation and which is superimposable over and rotatable about said center aiming point and having an overlay pointer at its outermost point whereby an imaginary axis extends through said center of rotation and said overlay pointer, said imaginary axis corresponding to said fixed vertical axis in length, and having a profile view of said game animal inscribed about said imaginary axis, said profile view having an overlay kill zone comprising the profile game animal head area, profile game animal neck area and profile game animal breast area;
- and,
- h. written instructions for the employment of said target printed in between said periphery and said rectangular background.
