Hornady 397144 A-Tip Match Seating Stems 338 Cal 300gr Bullets

The Hornady 397144 A-Tip Match Bullet Seating Stems deliver precision reloading for 338 caliber 300-grain A-Tip Match bullets. These specialized seating stems eliminate bullet deformation and ensure consistent seating depth for match-grade ammunition. Engineered specifically for Hornady's A-Tip Match projectiles, these stems provide the exact contact geometry needed for optimal bullet alignment.

What Makes This Different

Unlike generic seating stems that contact bullets at random points, the 397144 stems feature precision-machined contact surfaces that match the A-Tip Match bullet profile exactly. This bullet-specific design prevents tip damage and maintains the aerodynamic integrity that makes A-Tip bullets capable of sub-MOA accuracy. Standard seating stems can compress or deform bullet tips, reducing ballistic coefficient by up to 3%.

Key Features

• Precision-machined contact surface matches 338 caliber 300-grain A-Tip Match bullet profile
• Eliminates bullet tip deformation during seating process
• Maintains consistent seating depth within 0.001 inches
• Compatible with Hornady Lock-N-Load AP and Classic reloading presses
• CNC-machined from hardened steel for long-term durability
• Direct replacement for standard seating stems in Hornady dies
• Preserves bullet's ballistic coefficient for maximum downrange performance

These seating stems prove essential for competitive long-range shooters and precision rifle enthusiasts who demand consistent ammunition performance. The exact bullet-to-stem contact prevents the micro-deformations that can open groups by 0.2 MOA or more at extended ranges. Match shooters report improved consistency when switching from generic stems to bullet-specific variants, particularly with high-BC projectiles like the A-Tip Match series.
