Hornady 546358 Custom Grade 2 Die Set 308 Winchester Sizing Seater

The Hornady 546358 Custom Grade Series I 2 Die Set delivers precision reloading capability for 308 Winchester cartridges with professional-grade construction. This die set combines full-length sizing and bullet seating operations in two essential dies that maintain consistent cartridge dimensions and optimal bullet seating depth.

What Makes This Different

Custom Grade dies feature Hornady's Elliptical Expander technology that reduces case neck tension variations by up to 50% compared to standard expander balls. The Sure-Loc lock rings eliminate the common problem of die movement during setup adjustments. Internal components are manufactured to tolerances of ±0.0005 inches, ensuring repeatable ammunition that shoots to the same point of impact.

Key Features

• Full-length sizing die with Elliptical Expander for consistent neck tension
• Bullet seating die with built-in roll crimp capability
• Sure-Loc lock rings prevent die movement during reloading sessions
• Zip-Spindle design allows quick die changes without losing adjustments
• Compatible with all standard 7/8-14 TPI reloading presses

Match-grade ammunition production becomes achievable with dies that maintain cartridge overall length within 0.002 inches shot to shot. The sizing die returns fired brass to SAAMI specifications while the expander reduces case mouth damage during neck expansion. Competition shooters report improved group consistency when switching from standard die sets to Custom Grade tooling.
