Lyman H&I Bullet Sizing Die .355"

The Lyman H&I Bullet Sizing Die .355" is a precision reloading tool designed for handloaders who demand consistent ammunition performance and tight tolerances in their finished rounds. Built specifically for .355" caliber projectiles, this sizing die is essential for ensuring bullet diameter uniformity, which directly impacts chamber fit, accuracy, and firearm safety.

Constructed from high-quality steel, the die is engineered to resize cast or swaged bullets to exact diameter specifications. Its internal geometry applies uniform pressure across the bullet surface, helping to eliminate dimensional variance that can lead to pressure spikes or feeding failures in semi-automatic platforms. The compact design integrates seamlessly into most single-stage and progressive reloading presses.

This sizing die is ideal for reloaders looking to produce match-grade ammunition for competition or reliable duty loads for tactical training. The .355" specification ensures compatibility with standard 9mm, .38 Special, and .357 Magnum components sourced from commercial suppliers or recovered range brass.
