Overview
This two-die set is built for reloading bottleneck cases in .30-40 Krag, giving handloaders the tools needed to size, de-prime, expand the neck, and seat bullets in one setup. The full-length sizer is designed to bring cases to SAAMI minimum cartridge dimensions while holding headspace to minimum tolerances, and its vents help reduce the risk of case damage from trapped air or excess lubricant. The seater die includes a built-in roll crimper, allowing the bullet to be seated and secured at the same time. A shell holder is not included, so it is best suited for reloaders who already have the necessary supporting equipment.

Considerations & Trade-offs
- This is a full-length die set, so it is geared toward resizing cases to SAAMI minimum dimensions rather than preserving a fired case’s exact fit.
- A built-in roll crimper is included in the seater die, which is useful for securing bullets but may not suit every load style or bullet choice.
- A shell holder is not included, so the set is not fully ready to use without the correct separate holder.
- The set is specific to .30-40 Krag bottleneck case reloading, so it is not a general-purpose die set for other cartridges.
