Lee Precision 45/70 3 Die Steel
- Brand: Lee Precision
- Die Set: Three dies in one package
- Package weight: 1.3 lb
- Notes: No batteries required
The Lee 45/70 3 Die Steel set provides a complete, economical starting point for straight-wall 45/70 cases. Best for hobbyists and occasional reloaders who want a reliable, all-in-one kit without extra frills. The three-die arrangement typically includes a full-length sizer, a seating die, and a crimping die, simplifying setup for standard loads. A potential limitation is that aluminum or steel build, while sturdy, may appeal less to users who want ultra-smooth feel or extended life from premium components. This set is well-suited for newcomers and shooters who value straightforward operation.
Redding Reloading Three Die Set, 45-70 U.S. Govt
- Brand: Redding
- Includes: Full Length Sizer Die with decapping unit, Expander Die, Neck or Profile Crimp Die
- Reference: Advanced full-length sizing for straight-wall cases
Selected for precision-minded reloaders, this Redding three-die set emphasizes durable machining and deliberate, repeatable sizing and seating. The full-length sizer ensures consistent case dimensions, while the expander and neck- sizing components help maintain accurate bullet alignment. Best for experienced reloaders who want reliable flat-topping and precise crimping control in one package. A potential drawback is that the setup can be more involved than simpler two-die sets, so beginners should read the included steps carefully.
Redding Reloading Seating Die – 45-70 U.S. Govt
- Brand: Redding
- Die Type: Seating Die with storage box
- Function: Pushes bullet to the precise depth
- Note: Pair with a crimping step if needed
This seating die is ideal for shooters who prioritize exact seating depth and consistent bullet alignment. It pairs with a full reloading setup to produce uniform cartridge overall length. Best for reloaders who want a dedicated seating station separate from sizing, and for those who appreciate a compact storage box for organization. A caveat is that seating concentricity depends on overall press alignment and the quality of the rest of the die set.
Redding Competition Handgun Seating Die – 45-70 Government
- Brand: Redding
- Type: Seating die designed for competition use
- Storage: Plastic storage case included
- Note: This die does not crimp; a separate crimp die is required
Best for competition-focused reloaders, this seating die emphasizes precise bullet depth and consistent seating without crimping. It pairs well with a separate crimp die to maintain flexibility for a variety of loads. Choose this if you want a dedicated seating tool and plan to acquire a compatible crimping option later. Avoid relying on this alone if you need integrated seating and crimping in a single step.
Lee Precision 45/70 Factory Crimp Die
- Brand: Lee Precision
- Feature: Extra strong crimping action
- Quality: Made in USA
- Function: Ensures firm bullet retention in the case mouth
The Factory Crimp Die from Lee offers a strong hold on bullets, helping to reduce jostling in recoil and potential seating shift. Best for those requiring a robust, dedicated crimp tool to lock bullets in place, especially when using non-grooved bullets or heavier loads. A limitation is that it is a dedicated crimp die; you’ll still need separate sizing and seating dies to complete a full reloading setup.
Lee Precision 91113: Fl Size Die 45/70 Govt
- Brand: Lee Precision
- Function: Full length sizing with steel construction
- Lubricant: Resizing lubricant required
- Note: Part of a standard resizing station
This full-length sizing die is built for consistent case formation on 45/70 Government brass. Best for reloaders who want a reliable, heavy-duty sizing tool that stands up to frequent use. The need for resizing lubricant is a practical consideration for everyday use, and lubrication helps reduce tool wear and case friction during operation.
Lee Precision 45/70 Govern Gauge/Holder
- Brand: Lee Precision
- Use: For 45/70 GOVERNMENT cases
- Function: Helps trim to length and square the case mouth
- Origin: Made in USA
This gauge/holder helps ensure case length uniformity and square case mouths, which supports consistent seating and crimping. Best for reloaders who want quick checks on overall length and mouth squaring integrated into their workflow. A limit is that it’s a gauge/holder rather than a full die set, so it should be used in conjunction with sizing and seating dies for a complete rig.
Lee Precision Reloading 45/70 Gov Quick Trim Die Set
- Brand: Lee Precision
- Included: Trimming die body compatible with Lee quick trim case trimmer
- Function: Precisely trim brass to correct length
- Convenience: No calipers or measurement adjustments required
This QUICK TRIM die set aims to simplify length trimming by integrating with Lee’s deluxe quick trim trimmer. Best for reloaders who want fast, repeatable trimming without extra measuring steps. A potential limitation is that precise overall length still depends on proper machine setup and the trimmer compatibility; if you already own a different trimmer, ensure cross-compatibility before purchasing.
Buying Guide: How To Choose 45/70 Reloading Dies
Key questions to guide your purchase:
- What is my primary use? For target shooting, a dedicated seating die plus a crimp die helps maintain consistency. For hunting loads, a robust full-length sizer is often preferred to reduce case stretch.
- Do I need crimping in the same die set? Some sets include crimp dies; others require a separate crimp tool. If you want a compact solution, choose a three-die set with integrated seating and crimp capabilities.
- How important is precision seating depth? If seating depth consistency is critical, consider a dedicated seating die with a precise adjustment mechanism and a storage option for organizing components.
- What about maintenance and lubrication? Full-length sizing dies generally require resizing lubricant to minimize wear. Plan for lubrication as part of regular reloading practice.
- Is a separate gauge or trimmer needed? If you aim to trim to a specific length and square the mouths, a gauge or trimmer-compatible set can save time and improve uniformity.
Frequently Asked Questions
- What is the purpose of a seating die in a 45/70 reloading set? It seats the bullet to a precise overall cartridge length, ensuring consistent bullet depth and pressure.
- Do I need a crimp die for 45/70 loads? A crimp die helps lock the bullet in place, which improves accuracy and reliability, especially in lever-action rifles or hot loads.
- Can I use a 45/70 seating die with any press? Most standard seating dies fit common reloading presses, but verify shank size and threading with your press model.
- Is full-length sizing necessary for 45/70 cases every load? Full-length sizing is common to reset case dimensions, but neck-sizing or partial resizing may be preferred for specific rifles or brass longevity.
- What should I consider when buying a set vs. individual dies? A set provides a complete workflow (sizing, seating, crimping), while individual dies let you tailor a setup to your precise needs.
- Are Redding dies worth the extra cost? Redding products emphasize precise machining and durable construction, valuable for serious reloaders and long-term use.
