RCBS Seater Die Group A .223 Rem - 11138

This RCBS seating die is designed for .223 Rem cartridges and seats bullets to a precise depth while simultaneously applying a roll crimp to secure the bullet in the casing. The die is used with a reloading press by inserting the brass casing and bullet, then raising the ram to seat and crimp in one operation. It ensures consistent bullet seating depth and reliable bullet retention for handloaded ammunition.
