Just cast up a bunch of the NOE 314-129, and they drop .314, I've been told to lube them in a .313//.314 H&I die to keep the lube groove open, then use a push through Lee type die to size them to .309.
With little or no lube on the bands I'm wondering if I shouldn't use some sort of lube on the bands before pushing them through the push through die ??
