The Hornady A-Tip Match Seating Stem (MPN 397138) is a dedicated reloading press accessory designed to seat 6.5mm (.264") Hornady A-Tip Match projectiles without deforming their delicate, precision-machined aluminium tips. Engineered as a direct drop-in replacement part for Hornady Custom Grade New Dimension seating dies, this machined steel stem features an internal cavity contoured precisely to the steep ogive geometry of long, low-drag 135 grain and 153 grain A-Tip bullets. By contacting the bullet body lower along the ogive rather than the meplat, it maintains uniform cartridge overall length (COAL) and minimizes bullet runout during precision handloading.

Key Features

• Ogive-Specific Geometry: Machined with an internal cavity matched directly to the profile of 6.5mm (.264") 135 gr and 153 gr A-Tip Match bullets.
• Aluminium Tip Protection: Applies seating force along the projectile ogive to prevent tip flattening, marring, or concentricity loss.
• Direct Die Integration: Designed as an internal drop-in component for Hornady Custom Grade New Dimension bullet seating dies.
• Unpowered Mechanical Design: Operates entirely manually within standard bench reloading presses, requiring no power source or electrical certifications.

Who is the Hornady A-Tip Match Seating Stem For 6.5mm 135/153 Grain for?

• Precision rifle competitors loading 6.5mm match cartridges — requires coaxial bullet alignment in 6.5mm / .264 calibre cases to prevent tip deformation and minimise runout on engagement distances spanning 500 to 1,500+ metres.
• Long-range handloaders using Hornady 135 and 153 grain A-Tip projectiles — relies on a custom-profiled seating stem specifically contoured to the 135 grain and 153 grain ogive to apply seating force to the bullet body rather than the aluminium meplat.

Less suitable for: Reloaders seating projectiles outside the 6.5mm (.264") diameter or alternative weights, who require calibre-specific seating stems matched to their bullet diameter, or handloaders using non-Hornady dies, who require brand-native seating stems designed for their specific die manufacturer.
