Forster Bushing Full Length Sizing Die Bench Rest� Ultra Micrometer Seater Die 3 bushings (308 310 312) 7 PRC

The Forster Bushing Full Length Sizing Die Bench Rest® Ultra Micrometer Seater Die with 3 bushings (308, 310, 312) for 7 PRC delivers precision reloading control designed for competitive shooters and handloaders demanding consistency across shot strings. This die set combines a bushing-based full-length sizing die with a micrometer seating die, enabling independent control of neck tension while sizing the case body and shoulder—critical for maximizing accuracy and extending case life in precision rifle applications.

The bushing design allows you to select the amount of neck sizing tension applied to fired brass by choosing from the included bushings (308, 310, and 312 diameter). This prevents over-sizing the neck, which preserves case concentricity and reduces case work-hardening. The body and shoulder are sized down to minimum SAAMI dimensions, ensuring reliable feeding while the micrometer seating die provides repeatable bullet seating depth to within 0.001 inches—essential for maintaining node consistency in precision load development.

This setup is purpose-built for 7 PRC precision rifle reloaders, bench rest competitors, and long-range hunters who reload to exact tolerances. The 7 PRC's tight chamber design and modern cartridge geometry benefit significantly from this level of sizing control. By limiting neck expansion and maintaining consistent seating depth, shooters achieve tighter velocity spreads, reduced bullet runout, and improved downrange grouping—performance gains that compound across hundreds of precision rounds.

Forster's reputation in precision reloading tooling rests on tight tolerances and repeatable results. The micrometer seating die mechanism and hardened bushing components support long production runs without wear. For handloaders who prioritize consistency over speed, this die set represents the standard approach to competitive and precision rifle ammunition assembly.
