Lee Precision 45/70 Factory Crimp Die Review: A Must-Have for Reloaders?

The Lee Precision 45/70 Factory Crimp Die is a crucial tool for any reloader looking to achieve consistent and reliable crimps on their 45/70 cartridges. A proper crimp ensures that the bullet is held securely in the case, preventing bullet setback during recoil, which can lead to dangerous pressure spikes. This die, designed specifically for the venerable 45/70 cartridge, provides a consistent and uniform crimp, resulting in improved accuracy and overall shooting performance. It is aimed at reloaders of all skill levels, from beginners looking to get started to experienced handloaders seeking more precise control over their ammunition.

This factory crimp die is a single-stage reloading die, intended to be used on a reloading press. It creates a collet-style crimp, which is known for its even distribution of pressure around the bullet, preventing bullet deformation and improving consistency. This method offers an advantage over roll crimps, particularly when using cast bullets, which are commonly used in 45/70 loads. So, is the Lee Precision 45/70 Factory Crimp Die worth the investment? Let's dive into the key features and benefits to help you decide.

Key Features of the Lee Precision 45/70 Factory Crimp Die

  • Caliber Specific: Designed specifically for the 45/70 cartridge, ensuring a proper and accurate crimp.
  • Collet-Style Crimp: Provides a uniform and consistent crimp around the bullet's circumference, minimizing bullet deformation.
  • Easy to Use: Simple setup and adjustment, making it suitable for reloaders of all experience levels.
  • Durable Construction: Made from quality steel for long-lasting performance and reliability.
  • Affordable Price: An excellent value compared to other crimp dies on the market.

Pros of the Lee Precision 45/70 Factory Crimp Die

  • Improved Accuracy: The consistent crimp contributes to more uniform bullet release and improved shot-to-shot consistency, leading to tighter groups.
  • Enhanced Safety: Prevents bullet setback under recoil, reducing the risk of dangerous pressure increases during firing.
  • Increased Cartridge Life: The collet crimp doesn't overwork the case mouth, potentially extending the life of your brass.

Cons of the Lee Precision 45/70 Factory Crimp Die

  • Requires Adjustment: Needs to be properly adjusted for different bullet types and seating depths to achieve optimal crimping.
  • Single-Stage Operation: Requires a dedicated step in the reloading process, adding time compared to progressive presses.

Who Should Buy the Lee Precision 45/70 Factory Crimp Die?

This die is ideal for 45/70 reloaders who are seeking improved accuracy, safety, and consistency in their handloads. It's particularly beneficial for those shooting heavier recoiling loads, where bullet setback is a concern. Cast bullet enthusiasts will also find this die invaluable, as the collet-style crimp prevents deformation of soft lead bullets. If you are experiencing inconsistent crimps or want to achieve more precise control over your ammunition, the Lee Precision 45/70 Factory Crimp Die is an excellent addition to your reloading bench.

Consider this die if you are frequently reloading for: Hunting with 45/70, Cowboy Action Shooting, or simply enjoy the versatility and power of this classic cartridge. Also, compare this with similar offerings like the RCBS 45-70 Taper Crimp Die or the Redding Profile Crimp Die. While those are good options, they come at a higher price point, making the Lee die a great value for most reloaders. If you are using a progressive press, you may need to purchase a separate die station, but for most single stage reloaders, this is a direct plug-and-play product.

Conclusion: Is the Lee Precision 45/70 Factory Crimp Die Worth It?

At a price point of around $17, the Lee Precision 45/70 Factory Crimp Die offers exceptional value for reloaders seeking improved accuracy, safety, and consistency in their ammunition. While it requires proper adjustment and adds a step to the reloading process, the benefits of a consistent collet crimp far outweigh the drawbacks.

It's fine for occasional use. The value is definitely there since you get a lot of doses for cheap. I didn't find it "extra strength" though, felt more like a standard dose to me. It's a decent backup to have in the medicine cabinet.

I was looking at a similar oversized duvet at Pottery Barn that was like triple the price. Glad I went with the MIOTO instead! It’s light weight but still cozy enough for winter. No more cold feet in the middle of the night!
