Thanks guys. yes, the Model 45 was the original "magnum" of the RWS line. It was de-throned in 1981 by the model 48, which is still high up in the hierarchy. It was advertised as shooting 900 fps. My rifle was purchased by my father in 1980, and i received it in 2000.
I like to cut my meat up into strips and roll it in a mix of cornmeal and flour, with a dash of creol seasoning, then fried...mouth watering.
