Shotshells

Claim 1

A shotshell comprising in combination a cup-shaped metallic head having a central aperture, a primer cap mounted in said aperture, a tubular casing held within said metallic head by the sidewall thereof, a propellant charge within said casing, a basewad positioned between said propellant charge and said metallic head, an over-powder filler wad or wads adjacent said propellant charge and a shot load within said container and adjacent said filler wad, the said basewad consisting of two separate but interlockingly engaged resilient thermoplastic body components in superimposed upper and lower relationship, the upper of said body components comprising a cylindrical thermoplastic body having a frustoconical aperture centrally thereof, an upwardly extending tapered wall at the periphery of said cylindrical body and integral therewith and a peripheral recess at the outer, lower edge of said cylindrical body, said tapered wall being adapted to provide a gastight seal between said upper body component and said tubular casing; and the lower of said body components comprising a frustoconical thermoplastic body having an aperture centrally thereof adapted to receive said primer cap in firm, gastight relationship, an outwardly radially extending flange at the base of said frustoconical body and integral therewith and an upwardly extending wall at the periphery of said outwardly extending flange and integral therewith, the said upwardly extending wall being of a height not substantially greater than the height of the said frustoconical body.
