Hi . Just started shooting my (new to me ) Disco . Over the chrony yesterday , it put down some very impressive numbers . Using the JSB Reds it shot one string at a high of 923 fps to a low of 898 fps . Crow mags went from a low of 902 to a high of 934 . JSB Black tin went from a low of 914 to a high of 933 . How much energy is this impressive little rifle making .
