"Journee's Formula" for estimating maximum shot travel
Lead shot size diameter in inches, (expressed as a decimal), multiplied by 2200 gives the maximum potential distance in yards.
To convert SAMMI voluntary
numerical shot sizes to decimal, subtract shot size from 17.
Example: 17 - 6 (shot size) = 11 Move decimal two places to the left .11"
SAMMI #6 lead shot .11 x 2200 = 242 Yards
Federal 00B -measured, .325 x 2200 = 715 yards
