Quote: The twist rate of 1 in 12 was for the commercial hunting bullets in 8mm for both J and JS types in the various 8mm formats ( rimmed and unrimmed) and this was the accepted rate of twist as recorded by the German Association of Arms and Ammunition manufacture in 1926.
And the presently accepted civilian rate of twist, as witnessed e.g. by the indications in the DEVA reloading book, is 240 mm.
