Overview
This sizing die is built for handloaders who want to lubricate and size bullets with a controlled, repeatable setup. Its tapered mouth and hardened interior are designed to help guide bullets into alignment, while the 90-degree hole spacing makes lubrication easier even with harder modern lubes. It fits Lyman 450/4500 Lube Sizers and the RCBS Lube-A-Matic-2 Bullet Sizer/Lubricator, and it can also help crimp gas checks on gas check style bullets. For selecting the correct H&I die, the manufacturer recommends slugging the bore of your firearm and measuring.

Considerations & Trade-offs
- This die is specific to .358 H&I sizing, so it only fits projects that call for that diameter and format.
- It is designed for use with Lyman 450/4500 Lube Sizer and RCBS Lube-A-Matic-2 Bullet Sizer/Lubricator, so compatibility depends on having one of those systems.
- The product is intended to help crimp gas checks on gas check style bullets, which is useful for that application but not relevant to every bullet type.
- Lyman notes that selecting the correct H&I sizing die requires slugging the bore and measuring, so choosing the right die is a measurement-dependent step rather than a simple universal fit.
