RCBS Lube-A-Matic Bullet Sizing Die .310"

The RCBS Lube-A-Matic Bullet Sizing Die .310" is a precision reloading tool designed for ammunition manufacturers and serious handloaders who demand consistent bullet diameter control and superior lubricant application. This specialized die addresses the critical challenge of achieving uniform bullet sizing while applying lubricant evenly across the projectile's surface. It is particularly beneficial for those reloading precision ammunition.

Engineered by RCBS—a name synonymous with precision reloading equipment since 1956—the Lube-A-Matic design features a tapered die body that guides bullets smoothly through the sizing chamber while an integral lube applicator distributes lubricant evenly. This design eliminates the inconsistencies of manual lubing methods, ensuring a reliable process for reloaders. The .310" diameter specification makes this die compatible with .308 Winchester and .30-06 Springfield cartridges commonly used in various rifle platforms.

The die's compact footprint (1.95 x 0.8 x 3.6 inches) allows easy integration into single-stage or progressive press setups, and the 0.19 lb weight ensures minimal press stress during operation. This die excels for reloaders processing hard-cast or swaged bullets that require external lubrication before sizing. With its reliable performance, the RCBS Lube-A-Matic Bullet Sizing Die is an essential tool for any serious reloader.
