Hornady 397143 A-Tip Match Bullet Seating Stems 30 Cal 176gr

The Hornady 397143 A-Tip Match Bullet Seating Stems deliver precision seating for 30 caliber 176 grain A-Tip Match bullets. These specialized 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 cradle geometry needed for optimal bullet alignment.

What Makes This Different

Unlike generic seating stems that contact bullets at random points, the Hornady 397143 features a precision-machined cradle that matches the exact ogive profile of 176 grain A-Tip Match bullets. This targeted design prevents bullet tip damage and maintains consistent contact pressure across the bullet surface. Standard stems often create concentricity issues and bullet deformation that can affect accuracy by 0.5 MOA or more.
