8x56R R30S/8x56mm Steyr Snap Cap/Replica

A replica of the 8 x 56 mm Rimmed rifle cartridge developed in 1930 for the Steyr 1895 straight-pull bolt-action rifle, the service rifle of Austra-Hungary in World War I; many such rifles were converted from their original round-nosed 8 x 50 to the pointed-nosed (Spitzer) 8 x 56 during the 1930s, and historical/surplus M1895 rifles can often be found in the newer chambering. The CIP calls this cartridge "8×56mmR M30S".

Dimensions were taken from new production Prvi Partisan ammunition, and the model built in FreeCAD. The completed ABS "snap cap" (inert replica used to test-fire a gun without leaving the chamber empty) was tested in a Steyr-made M1895/30 carbine.

As this is a digital copy of a design that's 88 years old, it's entirely in the public domain.
