The Hornady Custom Grade Series III 2-Die Set for .338 Lapua Mag gives you the precision tooling you need to load consistent, accurate ammunition for long-range rifle work. This two-die set includes a full-length sizing die and a bullet seating die—the essentials for reloading this magnum cartridge. Hornady's Custom Grade dies are built to exacting standards with tight tolerances and smooth internal finishes, so they'll serve you reliably through thousands of reloads without degradation.
The sizing die features Hornady's Zip Spindle design, which locks positively to prevent slippage during the resizing stroke. Fine threads cut on both the spindle and spindle collet let you make small, precise adjustments or quick, larger movements—whatever your load development demands. The seating die employs an in-line bullet seating system and includes a built-in crimper, giving you control over both bullet seating depth and case mouth tension in one tool.
Whether you're developing loads for a precision rifle, preparing for a long-range hunt, or working up match ammunition, these dies are engineered to handle the demands of .338 Lapua Mag reloading. The smooth finish lock rings include wrench flats for secure mounting in your press, and the included die boxes keep your tools organized and protected. Hornady backs Custom Grade dies with a lifetime guarantee against breakage or wear from normal use.
