Description

The Lee Collet Die Set – 375 H&H Mag, 2 Piece is an exceptional reloading solution tailored for precision-focused handloaders working with this powerful magnum cartridge. Designed specifically for cases previously fired in your own rifle, this die set optimizes case neck alignment and maintains brass integrity for extended case life. This action results in a perfectly centered case neck, significantly minimizing run-out and ensuring more consistent bullet seating and improved accuracy.

Unlike full-length sizing dies that can overwork brass, the collet system resizes only the neck. This technique reduces unnecessary stress on the cartridge body, preserves the fire-formed shape of the brass, and helps maintain smooth chambering and extraction. The reduced run-out directly contributes to tighter groupings and more consistent ballistic performance.

Complementing the collet die is the Dead Length Bullet Seater Die. This tool seats bullets to a uniform depth without disturbing the case neck alignment created by the collet die. The combination ensures optimal pressure build-up and consistent ignition, which are key to maintaining performance and reliability in high-powered hunting or long-range shooting scenarios.

The set includes essential accessories to support your reloading process: a universal shell holder that securely holds the case during resizing and seating, a powder dipper for consistent powder charges, and a detailed instruction and load data sheet. These components make the die set user-friendly and effective for both beginner and seasoned reloaders.

Built with durability and precision in mind, the Lee Collet Die Set – 375 H&H Mag offers not only a cost-effective, but also reliable choice for reloaders who demand accuracy and case longevity. It’s a smart investment for producing top-quality handloads tailored to your firearm.

Brand

Lee Precision

The Lee reloading business started in Richard Lee's home workshop in 1958 with the creation of the renowned Lee Loader for shotgun shells. By the early sixties, loaders for rifle and pistol ammunition were introduced, bringing over one and a half million shooters into the world of reloading with their cost-effective and efficient tools. Each Lee product is initially unique. Lee's innovations include dies, presses, crimpers, powder measures, priming tools, scales, bullet molds, melters, sizers, lubricants, turrets, trimmers. Their various accessories all set industry standards. Their products undergo a strict three-question test: Does it meet a real need or surpass other available products? Can it be produced affordably? Would I personally buy one? Only products that answer "yes" to all three questions are introduced to the market. Lee products come with exceptional guarantees. Customers can receive a full refund within 30 days if not completely satisfied. Their dies are guaranteed to produce ammunition with less bullet run-out than any other brand. Ammunition loaded with their collet dies is guaranteed to achieve the smallest groups, even compared to custom bench rest equipment. For sixty years, Lee Precision has been serving reloaders worldwide. They remain 100% family-owned.
