Lyman Pro Carbide Trim Die 300 AAC Blackout - 7702111

The Lyman 7702111 Pro Carbide Trim Die delivers consistent case trimming for 300 AAC Blackout brass, eliminating length variations that affect accuracy and feeding reliability. This carbide construction die maintains precise tolerances through thousands of trimming operations without requiring lubrication.

What Makes This Different

Unlike standard steel trim dies that require constant lubrication and wear over time, the carbide construction provides self-lubricating properties and extended service life. The precision-ground cutting surfaces maintain consistent case mouth dimensions within 0.001 inches, while the hardened carbide material resists wear from repeated brass contact. This die integrates with standard reloading presses using 7/8-14 threads.

Key Features

• Carbide construction eliminates need for case lubrication during trimming
• Precision-ground cutting surfaces maintain 0.001-inch tolerances
• Standard 7/8-14 thread pattern fits most reloading presses
• Engineered specifically for 300 AAC Blackout case dimensions
• Hardened carbide material resists wear and maintains sharp edges
• Integrated length stop ensures consistent case trimming
• Compatible with Lyman Universal Trimmer systems

Consistent case length proves critical for 300 AAC Blackout performance, particularly in semi-automatic platforms where feeding reliability depends on uniform case dimensions. The carbide cutting action produces clean, square case mouths that require minimal deburring. Subsonic and supersonic loads both benefit from the precise case preparation this die provides.
