speeding up brass prep for neck turning

[6bra1k]

this is dasher brass, so trim to length happens after fire form
i normally fl size with a small bushing to ensure the neck expands evenly
i neck expand with the correct expander for the turners being used
the 2 tasks are not that big of a deal in lots of 25, but when doing over 100 ,it takes TIME.
so i mounted a fl bushing die and the expander die in a DILLON 550 tool head. adjusted dies to ensure correct sizing..and bingo the 100 plus cases were done in no time.
all ready for turning

So what kind of neck wakk tolerances are you getting? How did you measure them?

not sure what your question has to do with the post, but
i do a rough turn to just under 13 with a k and M, then a final with a PUMKIN.
MY .012 necks work out to 0.0120....close enough for me
