I am waiting for my shipment of BTB 280 WFN GC. My question is can I use my RCBS carbide die set for loading these bullets. Will the expander that came with the sizer die work, or do I need something else. Also do I have to flatten out the seater plug edges to seat the bullet with the .340 meplat. The bullets are sized .432.
