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.

Thanks for the advice. The lyman "M" die sounds good, I'll have to get one. Have been shooting Hornady 240 XTP bullets with very good results, the necks grip is very tight. But I didn't know how it will work for cast bullets. I also seat and crimp in two steps, seems to give a better crimp
