Hornady 397139 A-Tip Match Bullet Seating Stems 6mm Precision

The Hornady 397139 A-Tip Match Bullet Seating Stems deliver consistent bullet alignment and optimal concentricity for 6mm precision reloading applications. These specialized seating stems eliminate bullet deformation while ensuring repeatable seating depth across every round.

What Makes This Different

Unlike standard seating stems that contact bullets at a single point, these A-Tip specific stems feature a contoured tip design that matches the unique profile of Hornady's A-Tip Match bullets. The precision-machined contact surface distributes seating pressure evenly, preventing bullet tip damage that can occur with generic stems. This specialized geometry maintains the aerodynamic integrity of the A-Tip's aluminum tip while achieving consistent overall cartridge length variations within 0.002 inches.

Key Features

• Precision-machined seating surface designed specifically for A-Tip Match bullet profile
• Eliminates bullet tip deformation during seating process
• Maintains consistent overall cartridge length within 0.002 inches
• Compatible with Hornady Lock-N-Load AP and Classic presses
• Hardened steel construction for extended service life
• Reduces runout and improves bullet concentricity
• Fits standard 7/8-14 threaded seating dies

Competitive shooters and precision reloaders report improved accuracy consistency when using bullet-specific seating stems compared to generic alternatives. The matched contact surface prevents the micro-deformation that can affect ballistic coefficient and downrange performance. Long-range applications particularly benefit from the enhanced concentricity, with many users achieving sub-0.5 MOA groups at extended distances.
