Squirrel: 4″ high in partial upright position. Printed full size, the 1/2″ Target Circles are spaced 0.5″, 1″ and 1.5″ apart for different zeroing options. Instead of ranging squirrels, suggest hunting them inside +/-1″ POI range, typically 20-85yds with a .22lr. 4″ high target at maximum 85 yds will be more than 1.3 mildots (at 10x with SFP scope.)
Rabbits: 6″ and 5″ high in typical crouched position. Printed full size, the 1/2″ Target Circles are spaced 0.5″, 1″ and 1.5″ apart for different zeroing options. If the 6″ rabbit is printed to “fit the page”, the height is only 5″ and the target circle spacing reduces to 0.42″, 0.833″, and 1.25″ (not as useful.)
