AusFclass said:the forster co ax looks well enginered for leverage but i dont see how having the die and case wobble around can be conducive to straight ammo??

Ha! That's exactly why the cases are so straight! any slight misalignment in machining from the top to the base is corrected by allowing the dies to "float"
Traditional presses can ruin brass if out of alignment, or if dies have machining that is not straight because there is no give to any part so it forces the brass to whatever formation it creates when sizing.
I've actually seen brass that had a slight resemblance to the "leaning tower of Piza" because of a cheap traditional press and dies.

i see what your saying but in my experience "start straight . . . finish straight" rings in my ears. on a forster during neck sizing the neck will start sizing before the case has aligned with the die as there is nothing to guide the body untill it is fully inside the die??? if the base of the case is in a shell holder aligned with the die to start with i would think that would be a good start for the neck process.
i havent seen any good detail of how the bottom floating case holder works on the forster.
what sort of run out are you getting in loaded ammo and on F/L sized cases?
