Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 116 words
A shotgun shell containing a shot dispersion control device comprising; a base casing, a cylindrical body extended from said casing, a powder charge and wadding positioned in said base casing, a shot dispersion control device positioned in said cylindrical body intermediate its length, and shot surrounding said device, said device having stabilizing means at one end thereof, a longitudinal member having a surface of which a major portion monotonically increases from said stability means, said longitudinal member having an end opposite said stability means, said opposite end including a recess therein for receiving shot, whereby shot surrounding said longitudinal member will be dispersed upon firing depending upon the monotonical increase of said longitudinal member's outer surface.
