This is the universal powder for all medium-sized ri?e cartridges and bullets of normal weight. It is suitable for calibres ranging from 5.6 x 50 to 9.3 x 74 R. Decisive for the universality of R 903 is not only its adoptability to many different types of case forms, but also its ?exibility in terms of the ignition, which still leads to uniform and complete burn-up of the powder even when the load has a low density.
