Lee Precision .45-70 Government Full Length Sizing Die Only

If you're reloading .45-70 Government ammunition, a Lee Precision full-length sizing die is a fundamental tool for restoring fired brass to factory dimensions. Unlike neck-sizing dies that only work the neck of the case, a full-length sizing die resizes both the neck and body of the cartridge, making it the go-to choice for rifles where brass will be used across multiple firearms or when you need consistent, reliable case preparation. After firing, your .45-70 cases expand inside the chamber and don't always return to their original size—this die brings them back into spec and removes any bulges or irregularities from firing.

The Lee Precision approach to die manufacturing focuses on precision engineering at a sensible value. This .45-70 sizing die follows Lee's proven design philosophy: straightforward, effective, and built to handle the demands of serious handloaders who want dependable results without unnecessary complexity. Whether you're preparing brass for hunting loads or target ammunition, this full-length die ensures your cases are sized uniformly for reliable feeding, chambering, and consistent performance downrange.

Setup is straightforward once you understand the fundamentals: clean your fired cases, adjust the die to bump the shoulder back by 0.001 inch, lock it in place, and run cases through with proper lubrication. Check your shoulder bump periodically during your reloading session to maintain consistency. With careful technique—avoiding excessive working of the brass—this die will help you get years of reliable use from quality .45-70 brass.

Frequently Asked Questions

What's the difference between a full-length sizing die and a neck-sizing die?

A full-length sizing die resizes both the neck and the body of the cartridge case, while a neck-sizing die only works the neck. Full-length sizing restores the entire case to factory dimensions and is suitable for use across different rifles chambered in the same caliber, making it the standard choice for most reloaders.

Can I use this die if I reload .45-70 for multiple rifles?

Yes. A full-length sizing die is versatile and designed to work with any rifle chambered in .45-70 Government, which makes it ideal if your brass will be fired in different firearms or if you want to standardize case prep across multiple guns.

What do I need to do to set up this die properly?

Clean your fired cases, install the die in your press, and adjust it gradually until the case shoulder is bumped back approximately 0.001 inch. Lock the die in place, lubricate your cases, and run them through. Check the shoulder bump periodically during reloading—every 10 cases or so—and adjust the die as needed to maintain consistency.

Does this product come as a complete reloading die set?

No—this is the sizing die only. It is sold separately and does not include other dies or reloading components; you will need to source a sizing die kit or additional dies if your reloading setup requires them.
