That middle boolit looks like the lyman that my CBE is copied off
It works but nothing to spare - at 100 yards the LEE 5003R does much better fouling wise. But that thing gets unstable out at distance (400yards in a 20"twist + a little bit of wind upsets it)
Whats the logic with the 2 big knurled boolits is that to take up windage or more lube (or both)
