The 1934 DWM load for the 11.2x60 Schüler was a 21.5 g = 332 gr jacketed bullet ahead of 4 g = 61.7 gr of the long obsolete R5 powder for 680 m/s = 2231 fps.
From my experience R5 was a smokeless powder with a burning rate slightlx faster than 4064. I usually substitute it with the slower N140 for a start. Many rifles shot to the sights with this recipe.
