Special Features

• The Elliptical Expander delivers smoother neck sizing than standard ball expanders, reducing friction and case neck stretch across the belted Weatherby brass that reloaders rely on for multiple loading cycles.
• The Zip Spindle uses a series of light threads on both the spindle and collet to eliminate slippage during seating depth adjustments, making incremental changes fast and repeatable without knuckle-busting lock-down force.
• The inline floating alignment sleeve in the seating die holds the bullet, case neck, and seating stem in perfect alignment before the bullet enters the case neck, reducing runout and improving concentricity that matters at the extended ranges this cartridge is built for.
• The built-in roll crimp in the seating die secures the bullet without a separate crimping die or extra press pass.
• Sure-Loc rings clamp around the entire die body under constant pressure, protecting die threads and holding die position through long loading sessions.

Practical Benefits

• Full length sizing returns cases to SAAMI minimum dimensions, making these dies the correct choice for any bolt rifle where cases are not exclusively dedicated to a single firearm.
• The 257 Weatherby Magnum is a premium long-range cartridge ideal for deer, elk at moderate distances, and varmints where extreme velocity and flat trajectory are the priority, and precision handloads built on this die set let you push that potential further than factory ammunition.
• The 7/8 by 14 thread fits virtually every single-stage, turret, and progressive press on the market, making this set compatible with your existing reloading setup without adapters.
• The Elliptical Expander and inline seating alignment work together to reduce the concentricity variation and velocity spread that show up as vertical dispersion at long range where the 257 Weatherby is most often shot.
• If you handload for a 257 Weatherby Magnum and want a die set precise enough to match what that cartridge is capable of, the Hornady Custom Grade 2-Die Set (546276) gives you that foundation with a lifetime guarantee behind it.

The Hornady Custom Grade New Dimension 2-Die Set (546276) for 257 Weatherby Magnum is a reliable pick for serious rifle reloaders who want precision full length sizing, reduced case neck stretch, and American-made durability in a press-compatible package built to last.
