Optimizing .222 Remington Ammunition: The Lee Factory Crimp Die

For any serious reloader, precision and consistency are the cornerstones of crafting superior ammunition. Whether you're a competitive target shooter striving for sub-MOA groups, a dedicated hunter seeking optimal terminal performance, or simply an enthusiast who values reliable, high-quality rounds, the integrity of your finished cartridges is paramount. One often-overlooked yet critical step in the reloading process, especially for rifle ammunition, is the application of a proper crimp. This is where specialized tools, like the Lee Factory Crimp Rifle Die for the .222 Remington cartridge, come into play, offering a definitive solution to common reloading challenges.

Why is Crimping Rifle Ammunition Essential?

The act of crimping a rifle cartridge involves applying pressure to the case mouth, securing the bullet firmly in place. While some reloaders debate the necessity of crimping for all rifle rounds, particularly those used in bolt-action rifles where neck tension alone might suffice, there are compelling reasons and situations where a consistent, controlled crimp becomes indispensable.

Preventing Bullet Setback

One of the primary concerns addressed by crimping is bullet setback. This phenomenon occurs when the bullet is pushed deeper into the cartridge case. In tubular magazines, the recoil from firing can cause bullets in adjacent cartridges to be jarred forward, impacting the tip of the bullet ahead of them and potentially pushing it into its case. More commonly, in semi-automatic rifles, the forceful cycling of the action can slam the cartridge forward into the chamber or against the feed ramp, causing the bullet to set back.

Why is bullet setback dangerous? A consistent overall length (OAL) is crucial for safety and performance. When a bullet sets back, it effectively reduces the internal volume of the cartridge case. This reduction in volume can lead to a sudden and significant increase in chamber pressure upon ignition. Extreme pressure spikes can be hazardous, potentially damaging your firearm and posing a risk to the shooter. The Lee Factory Crimp Die provides a robust solution, firmly securing the bullet to prevent such dangerous scenarios, ensuring your handloads remain safe and reliable.

Enhancing Powder Burn Consistency

A proper crimp can also contribute to more consistent powder ignition and burn. By providing uniform resistance to the bullet's initial movement, a crimp helps to build consistent pressure within the case before the bullet starts to travel down the bore. This consistency translates directly into more uniform muzzle velocities, which is a critical factor for achieving tight groups and predictable trajectories. For hunters, this means more reliable bullet placement at varying ranges, and for target shooters, it means minimizing vertical stringing on the target.

Improving Feeding Reliability in Semi-Automatics

For rifle cartridges used in semi-automatic firearms, a robust crimp is often non-negotiable. The violent cycling of these actions, characterized by rapid feeding, chambering, and extraction, can dislodge bullets that are only held by neck tension. A firmly crimped bullet resists these forces, ensuring smooth, reliable feeding from the magazine into the chamber. This reliability is paramount in scenarios where consistent function is critical, such as competitive shooting or self-defense applications. The Lee Factory Crimp Rifle Die ensures that your .222 Remington rounds cycle flawlessly, shot after shot.

Protecting Bullet Integrity

Some bullet types, particularly those with exposed lead tips or delicate polymer tips, can suffer damage during the feeding process in certain firearm designs. A crimp, especially a collet-style crimp like that provided by the Lee Factory Crimp Die, can offer additional protection by encapsulating the bullet base more securely within the case mouth, minimizing potential deformation during cycling. This helps maintain the bullet's ballistic coefficient and accuracy potential.

Introducing the Lee Factory Crimp Rifle Die for .222 Remington

The Lee Factory Crimp Rifle Die, specifically designed for the .222 Remington cartridge (product identifier 90816), is revered among reloaders for its unique approach to crimping. Unlike traditional roll crimp or taper crimp dies, the Lee FCD employs a collet-style mechanism that applies a uniform crimp around the entire circumference of the case mouth, independent of case length. This design eliminates the common issues associated with other crimping methods and offers distinct advantages for the discerning reloader.

How Does the Lee Factory Crimp Die Work?

The Lee Factory Crimp Die operates on an innovative collet principle. As the reloading press ram raises the cartridge into the die, a set of four hardened steel fingers (collets) are forced inwards by a tapered mechanism. These collets press the case mouth uniformly against the bullet, creating a secure and concentric crimp. This method is superior because it does not roll the case mouth into a cannelure (a groove on the bullet) and does not depend on consistent case length for a proper crimp. Even cases trimmed to slightly different lengths will receive an equally effective crimp.

Key Features and Benefits:

• Uniform, Concentric Crimp: The collet design applies pressure evenly around the bullet, ensuring a perfectly concentric crimp. This consistency is vital for maintaining accuracy and reducing variations in bullet pull.
• Independent of Case Length: Unlike roll crimps that require a specific case length to engage a cannelure, the Lee FCD crimps the case mouth regardless of slight variations in case length. This simplifies the reloading process and reduces the need for obsessive case trimming.
• No Case Mouth Distortion: Traditional crimping methods, especially heavy roll crimps, can sometimes deform the case mouth, leading to issues with chambering or affecting neck tension. The Lee FCD's collet action avoids this by only applying pressure where needed, leaving the case mouth structurally sound.
• Removes Case Mouth Bell: After expanding the case mouth for bullet seating, it's common for a slight "bell" or flare to remain. The Lee FCD effectively removes this bell, ensuring the cartridge fits smoothly into the chamber without catching, thereby enhancing feeding reliability.
• Enhanced Neck Tension: Even if you do not use a crimp for setback prevention, the Lee FCD can still be used to refine neck tension. For certain applications or bullet types, a slight, uniform crimp can provide an extra measure of bullet retention, especially beneficial for heavy-recoiling cartridges or when cycling through vigorous semi-automatic actions.
• Improved Accuracy Potential: By promoting consistent bullet pull and powder ignition, the Lee FCD contributes to more uniform muzzle velocities and reduced standard deviations, which are direct pathways to improved group sizes.
• Versatility with Bullet Types: Whether you're loading traditional cup-and-core bullets, boat-tail projectiles, or even those without a cannelure, the Lee FCD provides an effective crimp. Its design accommodates various bullet profiles without requiring a cannelure, making it incredibly versatile for all your .222 Remington reloading needs.
• Durability and Longevity: Constructed from high-quality steel, the Lee 90816 die is built to withstand years of rigorous use. Its robust design ensures consistent performance and a long service life, making it a reliable addition to any reloader's bench.

How to Integrate the Lee Factory Crimp Die into Your Reloading Process

The Lee Factory Crimp Die is typically the last die in your reloading sequence, after bullet seating.

1. Preparation: Ensure your .222 Remington cases are properly sized, primed, and charged with the correct powder.
2. Bullet Seating: Seat your bullet to the desired overall length (OAL) using your preferred seating die. It's important that the bullet is already seated to its final depth before crimping.
3. Die Setup: Install the Lee Factory Crimp Die into your press. Adjust the die body down until it just touches the shell holder, then lower the ram and turn the die body down an additional 1/4 to 1/2 turn. This provides a starting point for the crimp.
4. Crimp Application: Place a charged, bullet-seated cartridge into the shell holder and raise the ram fully into the die. The collets will engage the case mouth and apply the crimp.
5. Inspection: Remove the cartridge and inspect the crimp. It should appear as a subtle, uniform constriction around the bullet, without deforming the case mouth or distorting the bullet. If more crimp is desired, turn the die body down in small increments (e.g., 1/8 turn) and retest. Less crimp is achieved by turning the die body up.
6. Consistency Check: Periodically check your crimp during a reloading session to ensure consistency.

One of the significant advantages of the Lee FCD is that it is very forgiving to set up. Unlike roll crimps which can buckle cases if set too aggressively, the collet-style crimp is much less prone to case damage, making the setup process quicker and less frustrating.
