The RCBS Hand Case Neck Turner Kit (Model: 90401) is a precision manual case neck turner kit designed for handloaders who require absolute uniformity in their cartridge brass. This fully mechanical tool shaves microscopic layers of brass from the exterior of cartridge case necks to establish consistent wall thickness. By ensuring concentricity and eliminating wall-thickness variances, this tool helps reloaders minimize bullet run-out, achieve uniform neck tension, and ultimately reduce shot-to-shot velocity spreads for tighter downrange groupings.

Key Features

• Micrometer Adjustment Dial: Features an integrated dial that allows handloaders to adjust the cutter depth in precise 0.0005-inch increments.
• Zeroing Capability: The cutter design enables users to mechanically zero the cutting blade directly to the pilot or mandrel prior to dialing in the final thickness.
• Quick-Change Case Holder: An ergonomic, hand-held case holder secures the cartridge body securely, allowing smooth forward pressure and rotation without the need for small, obtrusive thumbscrews.
• Ambidextrous Design: The cutter housing is fully reversible, making it comfortable for both right- and left-handed operators.
• Broad Compatibility: This mechanical hand tool operates over a wide calibre spectrum, from .17 calibre up to .50 calibre.

Who is the Rcbs Hand Case Neck Turner Kit for?

• Precision rifle handloaders — seeking to eliminate velocity spreads and tighten long-range groupings can use this manual case neck turner kit to adjust cutter depth in ultra-fine 0.0005-inch increments, ensuring highly uniform brass walls.
• Reloaders processing low-to-medium volumes of custom rifle ammunition — benefit from a lightweight tool weighing just 0.07 pounds that supports cartridges ranging from .17 calibre to .50 calibre, allowing highly precise manual preparation without complex heavy equipment.

Less suitable for: extremely large bulk-reloading operations requiring power-driven neck-turning systems to prevent hand fatigue, where a heavy-duty, power-driven neck-turning system or lathe-style trimmer is better suited than a manual, hand-turned tool.
