1 1/2-12 to 1 1/4-12 Die Adapter Bushing: use Lee Large Series dies in competitor presses
The 1 1/2-12 to 1 1/4-12 die adapter bushing enables the use of Lee Large Series dies in presses with a different thread configuration. It is designed for users who need to load large-caliber cartridges such as 50 BMG, 416 Barrett, 577/450 Martini-Henry and 577 Snider using dies that would otherwise not fit their press.
The adapter converts the press's die holder thread (1 1/2-12) to the Lee die thread (1 1/4-12), allowing compatibility without permanent alterations to the press. This improves the user experience by making a wider die selection available for testing and production.
For large-bore reloading tasks, availability of suitable dies can be limited. The adapter increases versatility and reduces the need to purchase a dedicated press for a single die type. Experience from workshops shows that having a simple, interchangeable adapter streamlines setup and saves time.
Key benefits and considerations
- Direct compatibility with Lee Large Series dies for the listed calibers: 50 BMG, 416 Barrett, 577/450 Martini-Henry and 577 Snider.
- Preserves the original press while allowing use of specialized dies from Lee.
- Supports comparative testing between die brands and models to refine bullet seating and sizing.
- Requires careful alignment and secure installation to prevent runout and ensure consistent results.
Before installation, verify the thread sizes on both your press and the Lee die. Proper assembly avoids looseness and centering issues under load. Do not overtighten; use appropriate tools and confirm the die is seated firmly in the adapter.
Installation and recommended practice
- Inspect threads on the press and adapter for debris or burrs before assembly.
- Screw the adapter into the press die holder straight and fully seated to ensure alignment.
- Thread the Lee Large Series die into the adapter until secure, avoiding excessive force.
- Test with a trial case to verify centering and function before full production.
- Keep threads clean and periodically check fit to maintain consistent experience and repeatability.
In short, the 1 1/2-12 to 1 1/4-12 die adapter bushing offers a practical way to use Lee Large Series dies in non-Lee presses for the specified large calibers. It enhances workshop flexibility and simplifies the integration of specialized dies into existing setups.
