Redding 45-70 Government Bullet Seating Die

The Redding 45-70 Government Bullet Seating Die is a precision reloading die built for handloaders who demand consistent, repeatable seating depth on every round. Whether you're assembling ammunition for a lever-action hunting rifle, a Sharps rifle, or a modern bolt-gun chambered in this historic cartridge, this 7/8-14 threaded die gives you the control needed to achieve tight velocity spreads and reliable ignition.

What sets this 45-70 bullet seating die apart is its micrometer-adjustable system, calibrated in .001" increments for fine adjustments without preset clicks. The sliding chamber design is smooth and consistent, eliminating the binding and stiction you might encounter in less refined dies. Because seating depth directly affects pressure and accuracy, the ability to dial in precise adjustments—and lock them in with a zero-set feature—takes guesswork out of your reloading bench.

Redding's reputation in competition and precision reloading circles rests on machining tolerances and quality control that show in the feel of every die. If you're developing loads for a 45-70 and want to move beyond generic tooling, this seating die rewards careful attention to your process. It's sold as a standalone die, so you can add it to an existing set or build your own 45-70 reloading kit.

Frequently Asked Questions

Will this die work with my single-stage reloading press?

Yes, provided your press accepts standard 7/8-14 threaded dies. This is the universal thread size for modern reloading presses.

What's the difference between a micrometer seater and a standard seating die?

Micrometer-adjustable dies let you fine-tune seating depth in tiny increments and lock a zero reference point, eliminating guesswork. Standard dies often rely on preset depths or rough adjustments, making it harder to achieve the consistency that affects accuracy and pressure.

Can I use this die to reload other cartridges?

No—this die is calibrated specifically for 45-70 Government ammunition. You'll need a separate seating die for each cartridge you load.

Is this die sold as part of a complete 45-70 die set?

This seating die is sold separately. You can purchase it standalone or combine it with a sizing die and decapping tool to build your own reloading set.
