i'm using a redding powder measure. am having trouble getting accurate measures with bullseye powder. it meters from 0 to + 3 tenths grain. i do not like that. any suggestions what measure i should try next. oh; i also have a older lyman with the smaller pistol drum feature. it also jams when "cutting" thru bullseye. any suggestions on a different measure. or, i'll just not use bullseye?
