38 Spec/357 Mag/357 Rem Max/38 S&W Neck Expanding
The Lyman Neck Expanding Pistol M Die is engineered for reloaders seeking consistent and precise case neck expansion for .38 Special, .357 Magnum, .357 Remington Maximum, and .38 S&W cartridges. Designed for use in standard reloading presses, this die is ideal for handloaders working with both cast and jacketed bullets, ensuring optimal bullet seating and alignment. Its two-step expansion process minimizes case stretching and enhances overall cartridge accuracy, making it a practical addition for anyone focused on quality handgun ammunition.
Product Overview
This Lyman M Die features a robust steel construction and is specifically designed to expand the necks of pistol cases in a controlled, two-stage process. The initial step gently enlarges the inside of the case neck to just under bullet diameter, while the second step slightly flares the case mouth, allowing for smooth, centered bullet seating. Unlike standard expander button dies, this design reduces the risk of case distortion and promotes longer brass life. Compatible with most single-stage and turret presses that accept standard 7/8'-14 threaded dies, it is a reliable choice for reloaders seeking repeatable results and improved ammunition performance.
