Part SD2731 for product 3 DI CARB 500 S&W MAG (Code=90288)
Due to this large diameter case and space limitations in the standard 7/8x14 dies, the carbide insert is extremely thin. To prevent cracking the carbide insert--if the cases have been fired in your gun--adjust the die a couple turns above the shell holder to prevent sizing the web portion of the case.
