Abstract

1,271,469. Base wads. DYNAMIT NOBEL A.G. 1 Dec., 1970 [2 Dec., 1969], No. 57128/70. Heading F3A. A base plug for a shotgun cartridge comprises a thermoplastic plastics member 2, e.g. of polyethylene, having a recess 7 for a propellant charge and a recess 3 in which is tightly fitted a plug 5 formed of compressed cardboard, compressed fibrous material, or a compressed mineral substance, the member 2 and plug 5 defining a continuous bore 6 for a primer powder. The plug 2, prior to insertion in the recess 3, is a smooth cylindrical body of greater axial length than the recess. On insertion, it is axially compressed so as to expand radially into longitudinal, helical or annual grooves 4. The cartridge comprises a thermoplastic plastics tubular portion 1 and a metal head 9.
