The Redding 66148 30-06 Springfield Premium Die Set With Micrometer Seater is a mechanical two-die handloading kit engineered for reloading .30-06 Springfield (.308 in / 7.62 mm bullet diameter) brass. Built with industry-standard 7/8"-14 threads, this set fits standard Australian reloading bench presses and pairs a full-length sizing die with a dedicated micrometer bullet seating die to provide consistent case dimensions and exact cartridge overall length (COAL).

Key Features

• Factory-Fitted Bullet Seating Micrometer: Features an adjustable seating top stem calibrated in 0.001" increments for repeatable, fine-tuned seating depth adjustments without hand tool trial and error.
• Free-Floating Carbide Sizing Button: Integrated into the full-length sizing die to reduce internal case-neck friction during expansion, preventing neck stretching and improving overall case concentricity while minimising the need for inside-neck lube.
• Full-Length Case Sizing: Returns fired brass to standard factory dimensions to ensure smooth chambering and cycling across various actions.
• Standard Thread Mounting: Precision-machined 7/8"-14 thread pitch ensures broad compatibility across standard manual reloading presses without power or electrical requirements.
