Title: SHOT WAD WITH HIGHLY COLLAPSIBLE HINGE PORTION
Abstract:
The invention uses a pair of curved opposed diagonal bars (24, 26) between a shot wad (12) and shot cup (16). The bars (24, 26) (deformable resistance members) buckle in the radial direction and end up basically flat between the shot wad (12) and shot cup (16) to give surprisingly and unexpectedly high amounts of collapse (80 % or more). This allows the space between shot wad (12) and shot cup (16) to be decreased significantly without sacrificing cushioning.
