Reloading Procedure for .357Sig - Die Setup

[kraigster414]

I have just started reloading .357Sig. Before I switch to my Dillon 650, I thought I'd start slowly (and safely) by sticking with my trusty old RCBS 4x4. I have the Lee dies as well as the Lee factory taper die. How do you guys set the sequence? I have no problem doing one at a time (like a single stage press) but once I get into the progressive mode, I have all kinds of problems because of the .357Sig neck. Any help would be appreciated.

I am using the Rainier 124 gr. bullet. Thanks.
