Thats pretty much what I expected to hear. Gosh I wish you could buy size sets for these noses like you've worked out. One base die could sport different bushings and bushing retainer screws so I could do .30 cal and the 8MM by changing those two items out and using a corresponding punch whatta great fix.
You managed to get the boolits concentricity correct on the longitudinal axis so that the potential off center balance doesn't make it go off course from it's RPM centrifugal stability...wobble.
I think I have it...huh?
