Special Features
- Straight configuration gives direct access through the receiver into the chamber on bolt actions and single shots, which many reloaders prefer for its precision and ease of use.
- Internal push rod design lets you gently seat a real bullet into the rifling using the same projectile you intend to load, instead of relying on a generic dummy profile.
- Thumb lock on the rod holds the measurement in place once the bullet contacts the rifling, so you can remove the tool and transfer the dimension to your calipers without losing position.
- Red anodized finish and Lock-N-Load branding make the Hornady C1000 easy to identify on a crowded loading bench and resist shop wear over time.

- Using this gauge with Hornady modified cases helps you keep seating depth consistent from batch to batch, which improves vertical dispersion and group size on target.
- Straight line access into bolt action and single shot chambers makes this tool ideal for precision rifles used in hunting fields, steel matches, or long range practice where small changes in jump affect performance.
