Abstract:
Shot shells with enhanced performance due to inclusion of an absorber between the shot wad and the shot payload. The absorber reduces the pressure within a shot gun's chamber during firing of the shell, such as by absorbing energy generated during the firing process, and may thereafter return some of the energy to the pellets as the absorber and pellets are propelled along the fireman's barrel. Accordingly, the absorber enables a shot shell to generate shot payload velocities that are greater than would be achieved without the absorber, typically at a lower internal chamber pressure. In some embodiments, the absorber has (1) a Young's Modulus of less than 2,000 psi (137.9 bar), (2) a compressive strength of at least 100 psi (6.9 bar) and/or less than 10,000 psi (689.5 bar), and/or (3) a tensile strength of at least 145 psi (10 bar) and/or less than 10,000 psi (689.5 bar).

Claim (Index 1):
A shot shell, comprising:\n a housing including:\n (i) a head that includes a primer; \n (ii) a casing that extends from the head to define generally cylindrical housing sidewalls that define an internal chamber with a mouth region distal the head; and \n (iii) a closure that closes the mouth region; \n a charge of propellant contained within the internal chamber; a shot wad extending entirely within the internal chamber and including a shot cup with a pellet-facing surface; a plurality of shot pellets within the shot wad; and a setback force absorber within the internal chamber and extending generally between the pellet-facing surface of the shot cup and the plurality of shot pellets; wherein the shot wad includes generally cylindrical wad sidewalls that extend from the shot cup and define a payload region that contains the plurality of shot pellets; wherein at least one of the plurality of shot pellets is in contact with the wad sidewalls; wherein at least one of the plurality of shot pellets is in contact with the absorber; wherein none of the plurality of shot pellets are in contact with the pellet-facing surface of the shot cup; wherein the absorber is in contact with the pellet-facing surface of the shot cup; wherein the absorber is configured to compress resiliently in response to setback forces resulting from combustion of the charge of propellant; wherein the absorber is forming of at least one of cork and rubber, and wherein the absorber has a Young's Modulus of less than 5,000 psi (345 bar); and wherein the absorber is formed from a different material than the shot wad and the plurality of shot pellets.
