RCBS Lock Ring Assembly Features The RCBS Lock Ring Assembly is engineered specifically for 1.5 to 12 inch dies the larger die thread pattern used when reloading oversized cartridges such as the .50 BMG .416 Barrett and .460 Steyr. Once a die is set to the correct height on the press this lock ring holds that position securely so the die does not need to be re-adjusted every time it is swapped in and out for a reloading session. This kind of repeatable setup is especially valuable with large caliber dies where fine-tuning die height can be more time consuming than with standard caliber dies. A properly locked die also helps maintain consistent case sizing and seating depth across a reloading run. Built to RCBS s standard of durable reloading hardware this lock ring is designed to hold firmly under the stress these larger heavier dies place on press threads. For handloaders working with .50 BMG .416 Barrett or .460 Steyr having a dedicated lock ring removes one more variable from an already demanding reloading process. Keeping die setup consistent from session to session helps ensure ammunition quality remains uniform round after round. This RCBS Lock Ring Assembly is a practical purpose-built accessory for anyone reloading these large caliber cartridges.
