Hornady 397141 A-Tip Match Bullet Seating Stems 7mm 166gr

The Hornady 397141 A-Tip Match Bullet Seating Stems deliver precise bullet seating for 7mm 166-grain A-Tip Match projectiles. These precision-machined stems eliminate bullet deformation during the seating process, ensuring consistent cartridge overall length and optimal accuracy potential.

What Makes This Different

Unlike generic seating stems that contact bullets at random points, these stems feature a precisely contoured tip designed specifically for the A-Tip Match bullet profile. The exact geometry match prevents bullet tip damage and maintains the aerodynamic integrity that makes A-Tip projectiles capable of sub-MOA performance. Standard stems often create pressure points that can deform bullet tips, leading to inconsistent ballistics and reduced accuracy.

Key Features

• Precision-machined to match 7mm 166-grain A-Tip Match bullet profile exactly
• Eliminates bullet tip deformation during seating process
• Maintains consistent cartridge overall length for improved accuracy
• Compatible with Hornady Lock-N-Load AP and Classic presses
• Hardened steel construction for long-term durability
• Easy installation with standard seating die threading
• Preserves aerodynamic properties of A-Tip Match bullets

Competitive shooters and precision reloaders recognize that bullet seating consistency directly impacts group size and vertical dispersion. These stems maintain the critical nose geometry of A-Tip Match bullets, preserving their ballistic coefficient and ensuring repeatable performance at extended ranges. The precise fit eliminates the slight bullet movement that occurs with generic stems, resulting in more uniform powder compression and consistent ignition characteristics.
