rcbs 9mm dies

[redriverhunter]

I was sizing some 9mm brass today and noticed that one of the cases mouth was bent to the inside and i though well i run it through the sizing die and that will be done. What i found was that the expander ball is just like the one I got on a universal decapping die. is the norm.
thanks

Yep,

RCBS expands and bells in the second die.

Use a loaded jacketed round to open the mouth to the correct diameter before trying to expand the case mouth.
