The Forster Products Inc full length sizing die for .338 Lapua Magnum is built for reloaders who demand consistency and precision in every round they produce. This die is engineered to handle the large magnum case head and shoulder geometry of the .338 Lapua, a cartridge favored by long-range hunters and precision rifle competitors. Forster's reputation for quality machining and meticulous finishing translates to dies that size cases concentrically, round after round, which directly impacts accuracy downrange.
What sets Forster apart is their attention to detail in the manufacturing process. Each die is machined from premium steel to tight tolerances, then hand-polished before and after heat treatment to ensure a superior surface finish. This care in production minimizes friction and wear, extending die life and maintaining consistent sizing pressures over hundreds of reloading cycles. The die incorporates Forster's Cross Bolt Die Locking Ring design, which clamps both ends of the split ring rather than relying on a screw threaded directly into the die body—a smarter approach that protects the die's threads from damage and loosening during use.
The integrated E-Z Out Expander button is positioned high in the neck area to provide proper support and alignment of the case neck during the expansion stroke. This geometry keeps the case axis true as it's withdrawn from the die, reducing the risk of case runout that can hurt accuracy. For .338 Lapua reloaders who invest time in handload development, this full length sizing die rewards precision with precision—the kind of tool that makes the difference between good groups and great ones.

A full length sizing die resizes the entire cartridge case—from the base through the shoulder and neck—to SAAMI specifications. This is essential for reloading, particularly when brass may have been fired in different firearms or has been reused multiple times. For a magnum like the .338 Lapua, full length sizing ensures reliable feeding and consistent chamber fit across different rifles.
Yes, this Forster die is designed specifically for .338 Lapua Magnum cases. It will size factory brass, once-fired cases, and reused brass back to SAAMI dimensions.
Forster dies are hand-polished before and after heat treatment and manufactured to tight tolerances, which reduces friction and wear. The Cross Bolt Die Locking Ring design protects the die threads and provides more secure clamping than screw-in rings. The E-Z Out Expander button is positioned higher in the neck to maintain case concentricity during expansion, a detail that contributes to more consistent reloads.
