@kurpfalzjäger I LIKE it! I love obscure/obsolete and/ or wildcat cartridges. At their time in cartridge history, there was a reason and/or purpose for their development. I find this extremely interesting? Maybe I need to get out more! Ha! Ha!
Some of us have been dreaming for years about reactivating this cartridge. But it is not easy , expensive , and anyway it would not have a commercial future.
August Schüler has developed some very interesting things , best example the 12.7x70 Schüler / 500 Jeffery. Unfortunately , the colonial history of Germany was close to the end and later the competition from England in terms of rifles and cartridges was very high. Cartridges like the 11,2x72 and 12,7x70 were hardly able to establish themselves at the time. Only the 500 Jeffery , alias 12,7x70 Schüler is surprisingly coming back.
I will continue to dream of the cartridge 404 Magnum Schüler !
