Redding Case Neck Gauge

The Redding Case Neck Gauge (Redding part no. 26400) gives handloaders a fast, simple way to sort brass by neck wall thickness and uniformity before it ever reaches a sizing die. Cases with inconsistent neck walls seat bullets less concentrically, so sorting them out ahead of time is a cheap way to tighten up group sizes.

Key Specifications

• Sorts cases by neck wall thickness and uniformity.
• Ships with two mandrel sizes, covering everything from .17 caliber to .338 caliber.
• Works as a fast, hand-operated go/no-go style sorting tool, not a full-length die.

Frequently Asked Questions

What caliber range does this gauge cover? .17 caliber up through .338 caliber, using the two mandrel sizes included.

Why sort brass by neck thickness? Uneven neck walls can cause inconsistent bullet tension and concentricity, so sorting cases first helps tighten up group sizes.
