Hornady 397142 A-Tip Match Bullet Seating Stems 7mm 190gr

The Hornady 397142 A-Tip Match Bullet Seating Stems deliver precision seating for 7mm 190-grain A-Tip Match bullets, eliminating bullet deformation and ensuring consistent cartridge overall length. These specialized stems solve the common problem of generic seating stems that can damage bullet tips or create inconsistent seating depth.

What Makes This Different

Unlike universal seating stems that contact bullets at random points, these stems feature a precisely machined cavity that matches the exact profile of the 190-grain A-Tip Match bullet. This bullet-specific design prevents tip deformation and ensures the stem contacts the bullet at the optimal location. The result is measurably more consistent cartridge overall length compared to standard stems, with variations typically reduced to under 0.002 inches.
