[quote]I have an 8x57 FL die but that's the biggest expander on hand, except when the .38-55 dies come in when I'l have a.375 expander. Expanding necks form .30 to .32 is easy enough but not sure if the cases would make the jump from .32 to .375 in one step even with the inside slicked up with Imperial Sizing wax.[quote]
I went from .270 to .308 using a Lee decapping/expander rod from a .308 die in my Lee universal decapper and never lost a case. Lee's rod has a lot of taper to it. miles
