I am reloading .45 auto for the first time.I actually haven't done any reloading for years and i guess it will show here.I cannot figure out how to bell the cases with my new dillon dies.An old set of rcbs in 9mm that i own have a separate die for belling but not so for these dillons.There is nothing in the instructions on how to do it although they say it needs to be done.I am using an old rockchucker single stage press if that matters but i think not.Im missing something obvious here but have grown tired of this riddle.Any help would be appreciated.Thanks
