Hornady 397135 ELD-X Bullet Seating Stem .277/270 Caliber

The Hornady 397135 ELD-X bullet seating stem delivers precision seating depth control specifically engineered for .277/270 caliber ELD-X projectiles. This specialized seating stem eliminates bullet deformation during the loading process while ensuring consistent overall cartridge length for enhanced accuracy potential.

What Makes This Different

Unlike generic seating stems that can compress or deform polymer-tipped bullets, this stem features a contoured contact surface designed to match the ELD-X bullet profile. The precision-machined contact point distributes seating pressure evenly across the bullet ogive rather than the fragile tip. This design prevents tip damage that can affect ballistic coefficient and terminal performance downrange.

Key Features

• Contoured seating surface matches ELD-X bullet profile for even pressure distribution
• Prevents polymer tip deformation during cartridge assembly process
• Precision-machined steel construction ensures dimensional consistency
• Compatible with standard 7/8-14 thread reloading dies
• Maintains consistent overall cartridge length within 0.001 inch tolerance
• Fits Hornady Custom Grade and Match Grade die sets
• Heat-treated steel construction resists wear from repeated use

Consistent seating depth directly impacts accuracy potential by maintaining uniform bullet jump to the rifling. The specialized contact surface reduces runout while preserving the aerodynamic properties that make ELD-X bullets effective at extended ranges. Reloaders working with match-grade components will notice improved concentricity measurements compared to standard seating stems.
