Let’s delve into a comprehensive review.
A Deep Dive into the Lee Precision 300 AAC Blackout Die Set
The Lee Precision 300 AAC Blackout die set is a popular choice among reloaders, particularly those new to the 300 BLK cartridge or those looking for a budget-friendly option. The set typically includes a full-length sizing die, a bullet seating die, and a powder-through expanding die. These three components work in concert to resize fired cases, expand the case mouth to accept a bullet, and seat the bullet to the correct depth. The full-length sizing die is crucial for ensuring that reloaded ammunition chambers reliably in AR-15 rifles, which often have tighter tolerances than bolt-action rifles. Proper sizing is the foundation of consistent accuracy and safe operation. The bullet seating die allows for precise control over the seating depth, which significantly impacts pressure, velocity, and ultimately, accuracy. Fine-tuning the seating depth is a critical aspect of load development for any cartridge, and the Lee die set provides the necessary adjustability for this purpose. The powder-through expanding die, unique to Lee Precision, serves a dual purpose. It not only expands the case mouth to prevent bullet damage during seating but also allows for the dispensing of powder directly through the die using a Lee Auto-Disk or Auto-Drum powder measure. This simplifies the reloading process and contributes to consistent powder charges. When looking into subsonic 300 blackout loads, the powder-through expanding die becomes even more important, as lighter powder charges require careful metering to ensure consistent performance.
| Die | Function | Key Feature |
|---|---|---|
| Full-Length Sizing Die | Resizes fired cases back to SAAMI specifications. | Ensures reliable chambering in AR-15 rifles. |
| Bullet Seating Die | Seats the bullet to the desired depth. | Allows for fine-tuning of seating depth for optimal accuracy. |
| Powder-Through Expanding Die | Expands the case mouth and dispenses powder. | Streamlines the reloading process and ensures consistent powder charges. |
One of the standout features of the Lee Precision die set is its use of a collet neck sizing die (in some versions or available separately). While the standard set includes a full-length sizer, the option to neck size can significantly extend case life and improve accuracy, particularly in bolt-action rifles. Neck sizing only resizes the neck of the case, leaving the body untouched. This results in a tighter fit between the case and the chamber, leading to improved consistency and reduced case stretching. However, it’s important to note that neck-sized cases may not always chamber reliably in AR-15 rifles, especially if the chamber is slightly out of spec. Another key element is the shellholder, which is generally sold separately. It’s essential to acquire the correct shellholder for the 300 AAC Blackout case to ensure proper alignment during the resizing and seating processes. The Lee Precision die set also benefits from Lee’s commitment to affordability. It often costs significantly less than die sets from other manufacturers, making it an attractive option for budget-conscious reloaders. However, this affordability sometimes comes at the expense of certain features or finishes found in higher-end die sets. Despite this, the Lee die set provides a solid foundation for reloading the 300 AAC Blackout cartridge and delivering accurate and reliable ammunition.
Using the Lee Precision Dies: A Practical Guide to 300 BLK Reloading
Reloading the 300 AAC Blackout with the Lee Precision die set, or any die set, follows a structured process. First, spent casings must be cleaned and inspected for any damage, such as cracks or excessive stretching. This step is crucial for safety and ensuring the longevity of your brass. Once cleaned, the cases are lubricated before being run through the full-length sizing die. Lubrication is essential to prevent cases from sticking in the die, which can damage both the case and the die. Lee Precision offers case sizing lubricant, or you can use other commercially available lubricants. After sizing, the cases are primed, either using a hand priming tool or a priming system integrated into a reloading press. Priming is the first step in preparing the case to receive a powder charge and a bullet. The next step is expanding the case mouth using the powder-through expanding die. This die not only expands the case mouth but also allows for the dispensing of powder directly into the case. Accurate powder measurement is paramount for consistent performance and safety. Use a reliable powder scale to verify the powder charge weight. With the powder charge in place, the bullet is then seated using the bullet seating die. The seating depth is adjusted to achieve the desired overall cartridge length (COAL), which is critical for optimal performance and reliable feeding from magazines. Finally, the loaded rounds should be inspected for any defects before being stored or used.
| Reloading Step | Description | Importance |
|---|---|---|
| Case Cleaning and Inspection | Clean and inspect spent casings for damage. | Ensures safety and extends case life. |
| Case Lubrication | Lubricate cases before resizing. | Prevents cases from sticking in the die. |
| Full-Length Sizing | Resize cases to SAAMI specifications. | Ensures reliable chambering. |
| Priming | Insert a new primer into the primer pocket. | Ignites the powder charge. |
| Case Mouth Expansion | Expand the case mouth to accept a bullet. | Prevents bullet damage during seating. |
| Powder Charging | Dispense the correct powder charge into the case. | Determines velocity and pressure. |
| Bullet Seating | Seat the bullet to the desired depth. | Affects accuracy and feeding reliability. |
| Inspection | Inspect loaded rounds for defects. | Ensures safety and reliability. |
Reloading for the 300 AAC Blackout requires careful attention to detail. The cartridge’s versatility means that you might be loading anything from light, supersonic bullets for hunting to heavy, subsonic bullets for suppressed shooting. Each type of load requires different powders, bullet weights, and seating depths. Consulting reputable reloading manuals and online resources is essential for developing safe and accurate loads. Pay close attention to minimum and maximum powder charges, and always start with a starting load and work your way up, carefully monitoring for signs of excessive pressure. One challenge often encountered with the 300 BLK is the tendency for the case shoulder to collapse during sizing, especially when using converted 223/5.56 brass. Using proper lubrication and carefully adjusting the sizing die can help minimize this issue. Also, when dealing with the 300 AAC Blackout, specifically when working with AR-15 platforms, it’s essential to ensure that the ammunition you produce functions flawlessly within your firearm. Regularly check the overall length of your rounds to prevent feeding issues. And finally, always double-check your powder charges, as even slight variations can have a significant impact on performance and safety.
