By Gawd it would be nice to have the Lee .312-155gr in 6 cav configuration. I go though a bunch in 3 differant Swiss K31's and now I find it shoots very well in a 308 Win. I'm scared to try it in the 06's and 303, I have a hard time keeping the supply up with a single cavity. I'll just bet there would be others that would very much like that proven design in a 6 cavity.
