Lyman 17 AUG .584 Height Scope Mount Rings Set
Lyman #17AUG Tunnel, Height 0.584" with 3/8" Blue Steel Dovetail Base
This precision-engineered Lyman #17AUG tunnel is meticulously crafted from a single solid piece of high-grade steel, ensuring exceptional durability and structural integrity for demanding metallic and semi-metallic reloading applications. The height of 0.584 inches is accurately measured from the bottom of the dovetail base at the center of the aperture, providing consistent alignment and optimal performance during bullet seating and crimping operations.
The 3/8-inch dovetail mount, constructed from robust blued steel, guarantees a secure and stable attachment to your reloading press or bullet seating die, minimizing any play or movement that could affect shot-to-shot consistency. This component is essential for precision handloaders seeking to maximize accuracy and efficiency in their ammunition assembly process.
Included with the tunnel are eight precision-machined steel discs, each engineered to exacting tolerances to facilitate smooth bullet passage and uniform crimping pressure. These discs are securely locked in place with a threaded cap, preventing any unwanted displacement during high-volume reloading sessions and ensuring repeatable results.
Designed with the serious marksman and ballistic technician in mind, the Lyman #17AUG tunnel is an indispensable tool for optimizing bullet seating depth and maintaining consistent cartridge overall length (COL), critical factors in achieving superior ballistic performance and reliability.
