• Inconsistent Ignition: A poor crimp can lead to varying ignition pressures, resulting in erratic velocities and reduced accuracy.
• Poor Feeding: Improperly crimped rounds can snag or deform during the feeding cycle, leading to frustrating jams.
• Reduced Component Life: Consistent crimping helps maintain the integrity of your brass.

The Lee Factory Crimp Die, specifically the 90838 model for 7-30 Waters, transforms the challenging task of crimping these rifle cartridges into a straightforward and reliable step in your reloading process. It’s an essential upgrade for anyone aiming for professional-grade ammunition performance.

The 7-30 Waters Cartridge: A Unique Niche Benefiting from Precision Crimp

The 7-30 Waters is a fascinating and effective wildcat cartridge that originated from the popular .30-30 Winchester. Developed by Ken Waters, this cartridge necked down the .30-30 case to accept 7mm (.284 caliber) bullets. It gained popularity, particularly in single-shot pistols and lever-action rifles like the Winchester Model 94, due to its improved ballistic coefficient and flatter trajectory compared to the .30-30, while still retaining sufficient energy for deer-sized game within practical hunting ranges.

• Ballistic Advantages: The 7mm bullets offer better aerodynamics, meaning they carry their energy more efficiently downrange and are less susceptible to wind drift than comparable .30-30 loads.
• Hunting Versatility: It's an excellent choice for medium-game hunting, offering a good balance of power and manageable recoil.
• Common Platforms: While often associated with single-shot firearms, its primary home in rifles has been in lever-actions, which inherently depend on a consistent and robust crimp to prevent bullet setback in the magazine tube during recoil.

Given the unique characteristics and common use in lever-action firearms, reliable bullet retention is not just a preference but a necessity for the 7-30 Waters. This is precisely where the Lee Factory Crimp Die 90838 shines, providing the ideal solution for handloaders of this distinct cartridge.

Understanding the Lee Factory Crimp Die Technology

What makes the Lee Factory Crimp Die (FCD) series, and specifically the 90838 model, so effective and user-friendly? Its secret lies in its patented collet design. Unlike traditional roll crimps that deform the case mouth into a cannelure (crimp groove) on the bullet, or taper crimps that merely straighten the flared case mouth, the FCD employs a unique method:

• Collet-Style Crimp: A four-segment collet compresses the case mouth around the bullet. This action creates a strong, concentric crimp that firmly grips the bullet without distorting the shoulder or body of the case.
• Crimp Groove Not Required: This is a revolutionary feature. The powerful collet system can form its own crimp groove directly into the bullet if one isn't present, providing uniform bullet retention regardless of bullet design. This means reloaders aren't limited to specific bullets with cannelures.
• Independent Crimping: The FCD is a dedicated crimping die, separate from the bullet seating operation. This allows reloaders to fine-tune seating depth for optimal accuracy, then apply a precise and consistent crimp as a separate, final step. This separation simplifies the reloading process and often leads to more consistent ammunition.
• Enhanced Case Life: Because the collet compresses the case mouth uniformly, it minimizes unnecessary stress on the brass, potentially extending the life of your valuable cartridge cases.

This innovative approach to crimping is why the Lee Factory Crimp Die has become a favorite among experienced reloaders and is highly recommended for cartridges where a strong, reliable crimp is essential, such as those used in lever-action rifles or for magnum handgun loads.

Key Benefits for the Discerning Reloader

When you integrate the Lee 90838 Factory Crimp Rifle Die into your reloading workflow, you're not just adding another tool; you're investing in a host of tangible benefits that elevate the quality and safety of your handloads:

• Superior Bullet Retention: The primary benefit. Eliminates bullet setback, particularly crucial for rounds loaded into tubular magazines where recoil can cause issues. This ensures consistent overall cartridge length (OAL).
• Enhanced Safety: Preventing bullet setback is a major safety consideration. When a bullet is pushed deeper into the case, it reduces case capacity, leading to a sudden, dangerous spike in chamber pressure upon firing. The FCD effectively mitigates this risk.
• Improved Accuracy and Consistency: A uniform crimp contributes to consistent ignition pressures. This consistency translates directly to more uniform muzzle velocities and tighter groups downrange. Removing variables from your handloads is key to precision.
• Reliable Feeding: Rounds with a proper crimp feed smoothly from magazines into the chamber, reducing the chance of jams and misfeeds during critical moments in the field or at the range.
• Versatility with Bullet Types: Because the die can create its own crimp groove, you have the freedom to choose from a wider variety of bullets, including those without traditional cannelures, without compromising on crimp integrity.
• Simplified Reloading Process: By separating the crimping step from bullet seating, you can focus on achieving the perfect seating depth first, then apply a consistent crimp. This streamlined approach makes the entire reloading process more manageable and precise.
• Reduced Brass Damage: The collet design applies pressure evenly around the case mouth, minimizing stress points and potential for case damage, which can help extend the lifespan of your valuable brass.

These benefits combine to provide handloaders with peace of mind and the satisfaction of producing ammunition that performs optimally every time.

Integrating the Lee 90838 Die into Your Reloading Process

The Lee 90838 Factory Crimp Die is typically the final step in the reloading process, after the case has been sized, primed, powder charged, and the bullet has been seated.

1. Preparation: Ensure your cases are trimmed to the correct length and deburred.
2. Sizing, Priming, Powder Charging: Complete these initial steps as usual for rifle cartridges.
3. Bullet Seating: Use your standard bullet seating die to seat the bullet to the desired overall cartridge length (OAL). Do not apply any crimp with your seating die if it's equipped to do so, as the FCD will handle this separately.
4. Install the Lee 90838 Factory Crimp Die: Thread the die into a station on your reloading press.
5. Adjust the Die: With a charged and seated round on the shell holder, raise the ram until the shell holder makes contact with the bottom of the die. Turn the die body down until you feel resistance, then lower the ram and turn the die down another 1/4 to 1/2 turn. This applies the desired crimp. A slight variation may be needed depending on your brass thickness and bullet type.
6. Crimp the Cartridge: Place the bullet-seated cartridge into the shell holder and raise the ram firmly into the die. The collet will then uniformly crimp the case mouth around the bullet.
7. Inspect: Remove the crimped cartridge and inspect it to ensure the crimp is uniform and firm. You may need to make minor adjustments to the die setting for your specific components.

By following these steps, you can consistently produce highly reliable and safe ammunition for your 7-30 Waters rifle.

Frequently Asked Questions About Rifle Crimping and the Lee FCD

Q: Do all rifle cartridges need to be crimped?
A: Not all rifle cartridges require a crimp, especially those for bolt-action or single-shot rifles where bullet setback is less of a concern. However, a light crimp can still improve consistency. For cartridges used in tubular magazine firearms (like many lever-actions that chamber 7-30 Waters), a strong crimp is essential to prevent bullet setback under recoil. The Lee Factory Crimp Die provides significant benefits even for cartridges where a crimp isn't strictly mandated, by ensuring consistent neck tension.

Q: How does the Lee Factory Crimp Die differ from a roll crimp or taper crimp?
A: A roll crimp folds the case mouth into a crimp groove (cannelure) on the bullet, typically used for revolver cartridges or some rifle cartridges with heavy recoil. A taper crimp simply removes the flare from the case mouth and applies light tension, common for semi-automatic pistol cartridges. The Lee FCD uses a unique collet crimp system that compresses the case mouth uniformly around the bullet, regardless of whether the bullet has a cannelure. This creates a more consistent and powerful hold, making it ideal for preventing bullet setback in rifles.

Q: Can I use this die with any 7mm bullet for 7-30 Waters?
A: Yes, one of the significant advantages of the Lee Factory Crimp Die is its ability to crimp any 7mm (.284 caliber) bullet designed for the 7-30 Waters, even if the bullet does not have a traditional crimp groove (cannelure). The collet system forms its own crimp into the bullet jacket, providing excellent retention.

Q: Is the Lee 90838 Factory Crimp Die difficult to set up?
A: No, the Lee Factory Crimp Die is generally very easy to set up. Its operation is straightforward, typically requiring only a simple adjustment to achieve the desired crimp level. Clear instructions are included with the die, making it accessible even for newer reloaders.

Q: Why is consistent bullet retention so important for 7-30 Waters in lever-action rifles?
A: In lever-action rifles with tubular magazines, cartridges are stacked end-to-end. During recoil, the inertia of the bullets in the magazine can cause them to push deeper into the case of the cartridge in front of them. This "bullet setback" reduces the internal volume of the case, which can lead to a dangerous and unpredictable increase in chamber pressure when the round is fired. A strong, consistent crimp from the Lee Factory Crimp Die 90838 is vital to prevent this.
