458 Lott Full Length Sizing Die

The Hornady 458 Lott Full Length Sizing Die is a precision reloading tool designed for shooters and handloaders who demand accuracy with large-bore African hunting cartridges. Whether you're a competitive long-range shooter, a professional guide, or a dedicated handloader, this full-length sizing die ensures consistent case dimensions and chamber fit—critical factors for reliable feeding, accuracy, and firearm longevity. The 458 Lott is a magnum-class cartridge favored for dangerous game hunting, and proper case preparation directly impacts downrange performance and shooter safety.

Hornady's full-length sizing die works by resizing the entire case body—from the case head to the shoulder and neck—to specifications that match your firearm's chamber. This process removes residual pressure marks and fire-formed variances left by the previous firing cycle, bringing each case back to uniform dimensions. Full-length sizing is essential for magnum cartridges like the 458 Lott because consistent case geometry directly affects powder charge weight accuracy, bullet seating depth precision, and overall cartridge integrity. The die's hardened steel construction withstands the high pressures generated during the 458 Lott's resizing process, ensuring durability across hundreds of reloading cycles.

This sizing die is compatible with all standard single-stage and progressive reloading presses that accept standard die threads (7/8"-14 TPI). Professional reloaders and dedicated hunters preparing custom ammunition for the 458 Lott will integrate this die into a complete three-die set alongside a decapping die and bullet seating die. Weighing just 0.65 lbs, the die is compact and easy to install, yet robust enough for the demanding pressures of large-magnum cartridge reloading. Proper setup with a quality reloading scale and caliper ensures repeatable results that translate to superior field performance and ethical shot placement on large game.
