Overview
This sizing die is built for reloaders who want a straightforward way to size and lubricate bullets for compatible Lyman and RCBS lube-sizer systems. Its tapered mouth and hardened interior are designed to support alignment during use, while the 90-degree hole spacing makes lubrication easier with harder modern lubricants. It also serves in gas check applications, helping crimp the gas check onto the base of gas check style bullets. For proper selection, the product notes recommend slugging the bore of your firearm and measuring before choosing the die.

Considerations & Trade-offs
- This is a caliber-specific sizing die, so it only suits users working with .309 bullets and compatible setups.
- It is designed for use with Lyman 450/4500 Lube Sizer and RCBS Lube-A-Matic-2, so it is not a universal stand-alone tool.
- The die is intended to help with bullet lubrication and sizing; it does not replace the need to slug the bore and measure before selecting the correct die.
- Its gas-check crimping function applies only to gas check style bullets, so it may not add value for other bullet types.
