What, if anything, will the Lyman M expander die do when loading cast bullets in 30-06 cases that the less expensive Lee universal expander die cannot do? I am hoping for responses from those who have used both.
I am assuming that since the Lee die is billed as 'universal' it can also be used with the .30 caliber carbine round. I am guessing this is not true of the Lyman M die for 30-06 since Lyman catalogs a separate .30 carbine M die.
