RWS R10 Pellets 4.49mm .53g .177 Following intensive development work, RWS introduced an especially elaborate production and control procedure for the RWS R 10 Match pellets. Very good material properties, tight production tolerances, professional shooting tests and careful packaging and marking processes are ideal preconditions for best RWS quality. The precise production guarantees absolute dimensional accuracy in length and weight. This means for the practical use: Smallest and uniform shot groups and sharply cut shot holes.
