I'm having some problems with my rcbs expander die in 30 carbine. It's a brand new die set. I'm screwing it in until it touches the shell holder then backing it off a half turn. With the expander stem just barely threaded in, it still makes contact with a sized case. I should be able to screw it in quite a bit before it ever makes contact. Anyone else have this problem? I tried backing the die out even more but that didn't help. I'm starting to think the expander plug is out of spec. The dies are steel not carbide.
