I hope Ford will stop by on your thread but for the 8x58R, the Shooter's Bible - 1940 (I think??) gives 2 grammes of R.5RRottweil) with the 12,7 gramme bullet also for 530 m/s at 25 meters (1600 kg./cm2)? As always, you are on your own with these numbers. The old powder Rottweil 5 is noted as being closely replicated with VV(Vihtavuori) N 140, which is my staple.

Also the 1940 Shooter's Bible gives that >> 2.1 grams W1920 powder with 10 gram bullet for 624 m/s at 25meters( 2000 kg./cm2).<<


Hochachtungsvoll,
