The Redding 22-250 Rem Premium Series Full Length Die Set (Model: 66106) is a 2-die rifle reloading set designed to resize fired and virgin .22-250 Remington brass back to minimum SAAMI factory chamber dimensions while providing micro-adjustable bullet seating. Manufactured from heat-treated, case-hardened alloy steel in Cortland, New York, this set incorporates factory-upgraded components, including a free-floating carbide expander button and a micrometer-adjustable seating head, to optimise cartridge concentricity and cycling reliability across standard bolt-action and single-shot rifles.

Key Features

• Floating Carbide Size Button: Self-centres on the decapping rod inside the full-length sizing die to reduce case neck stretch and preserve neck concentricity without requiring inside-neck lubrication.
• Bullet Seating Micrometer: Features laser-engraved graduations calibrated in 0.001" increments on the seating die for precise, repeatable control over overall cartridge length and bullet jump.
• Full-Length Case Resizing: Restores fired brass to factory SAAMI chamber specifications to ensure smooth extraction and chambering.
• Universal Press Interface: Machined with standard 7/8"-14 threads to mount directly into single-stage and turret reloading presses.
• Complete Set Packaging: Includes a full-length sizing die with decapping pin, a micrometer seating die, a hex wrench, and a hard plastic storage box that doubles as a cartridge loading block.

Who is the Redding 22-250 Rem Premium Series Full Length Die Set for?

• Varmint Hunters — Need full-length SAAMI dimension resizing with standard 7/8"-14 thread press compatibility to guarantee reliable cycling and chambering during high-volume field shooting.
• Target Shooters — Rely on precise 0.001" micrometer seating depth adjustments in this 22-250 rifle reloading die set to rapidly tune projectile jump across different bullet profiles.

Less suitable for: Reloaders seeking neck-sizing-only to maximise brass case life in a dedicated single bolt-action rifle; a dedicated 3-die set containing a neck-sizing die is better suited for that application.
