A shotgun shell is described which reduces recoil while increasing muzzle velocity. The shell comprises a first cylindrical base portion having an enlarged rim at its rearward end with a second cylindrical portion extending forwardly from the forward end of the first cylindrical portion. The second cylindrical portion has a diameter less than the diameter of the first cylindrical portion. A third cylindrical portion extends forwardly from the forward end of the second cylindrical portion and is designed to receive a shot cup containing shot therein. A powder chamber is formed in the shell and communicates with a central opening formed in the rearward end of the shell. A primer is positioned in the central opening for communication with the powder chamber through a small opening at the forward end of the central opening. The powder chamber has a cylindrical rearward portion and an outwardly and forwardly extending tapered portion at its forward end. The reduced diameter of the second cylindrical portion expands laterally during detonation of the shell so as to reduce the recoil. The small opening or hole between the central opening and the powder chamber shields the primer during detonation and prevents the primer from being blown rearwardly from the shell during detonation.

A shotgun shell having rearward and forward ends comprising, a first cylindrical base portion having an enlarged rim at its rearward end, a second cylindrical portion extending forwardly from said first cylindrical portion and having an outside diameter less than said first cylindrical portion, a third cylindrical portion extending forwardly from said second cylindrical portion and having an outside diameter substantially equal to the outside diameter of said first cylindrical portion and having a length substantially greater than the length of said first and second cylindrical portions, said base portion having a central opening formed in its rearward end for receiving a primer therein, at least said second cylindrical portion defining a powder chamber which communicates with said central opening, at least said third cylindrical portion defining a shot compartment, said powder chamber and said second cylindrical portion defining a wall portion capable of expanding laterally outwardly during the firing of the shotgun shell to reduce the recoil created by said firing.
