I'm using a Lee Pro Auto-disk powder measure with riser, and a powder-thru expander die in 38sp. Problem is, when I set the die for full disk travel on the powder measure, I get too much case expansion.
I'm using IMR Trail Boss, 1.09 disk for 4.6grs, and unless the disk moves all the way over, charges are inconsistent.
Any ideas?
Thanks,
Harpo
