11.2 X 51R KROPATSCHEK-HEISSIG

The 11.2 X 51R KROPATSCHEK-HEISSIG was produced from about 1872 until around 1950. It was a popular sporting cartridge originally intended for rifles of Kropatschek’s design which was put forward as a military rifle but never adopted. The cartridge was based on a shortened 11.15x60R Mauser M71 case even though no German companies produced cartridges in this calibre. Heissig was a Ferlach based gunsmith.
