Conquer Brass Bulges: The Essential Guide to the Lee Precision Bulge Buster Kit (UPC 734307904876)

For serious reloaders, especially those dealing with pistol ammunition, few frustrations are as persistent as the dreaded "case bulge." This common issue, often colloquially known as the "Glock bulge" due to its prevalence with brass fired from firearms with unsupported chambers, can render otherwise perfectly good spent casings unusable. When a cartridge case expands slightly beyond its normal dimensions, standard sizing dies simply can't reach the problematic area near the case head, leading to cartridges that won't chamber reliably, or worse, cause dangerous malfunctions.

If you’ve ever found yourself sifting through range brass, hoping to salvage a batch of .40 S&W, 9mm, or .45 ACP only to discover a significant percentage of bulged cases, then you understand the value of effective case preparation tools. The good news is, there’s a highly effective, widely trusted solution available: the Lee Precision Bulge Buster Kit, identified by UPC 734307904876. This ingenious push-through die adapter is engineered specifically to eradicate those stubborn bulge rings, ensuring your reloaded ammunition is consistently reliable and safe to use.

What Problem Does the Lee Bulge Buster Solve?

The core challenge for reloaders is consistent ammunition. When brass cases are fired, especially in firearms with less-than-fully supported chambers, the case can swell or bulge just above the rim. This deformation makes the case slightly oversized at its base. While most sizing dies work by reducing the case diameter from the mouth down, they often cannot reach this critical lower section that was previously supported by the chamber.

Consider these common scenarios where a Lee Bulge Buster becomes an indispensable tool:

• "Glock Smile" Elimination: Perhaps the most famous application, the Bulge Buster is the go-to solution for brass fired from Glock pistols and other firearms with similar unsupported chamber designs. These "smiles" or bulges are notoriously difficult to remove with standard dies and can lead to feeding issues, failures to chamber, or even dangerous over-pressures if forced into a tight chamber.
• Salvaging Range Brass: Many reloaders rely on collecting spent brass from shooting ranges. This brass often comes from a variety of firearms, some of which may have unsupported chambers. The Bulge Buster allows you to efficiently process and reclaim these otherwise unusable cases, turning what would be scrap into valuable reloading components.
• Improving Ammunition Reliability: An un-bulged case ensures smooth feeding and extraction, promoting reliable firearm function. For competition shooters or self-defense practitioners, consistent case dimensions are paramount for optimal performance and safety.
• Extending Case Life: While a bulged case often signals stress, properly resizing it with a push-through system like the Bulge Buster can sometimes extend its useful life, preventing the need to discard it prematurely.

How Does the Lee Bulge Buster Kit Work? A Push-Through Precision Solution

Unlike conventional sizing dies that operate by pulling the case up into a die, the Lee Bulge Buster Kit utilizes a unique push-through method. This system forces the entire brass case, base first, through a specialized carbide sizing ring. This approach allows the die to fully engage and resize the problematic lower section of the case that traditional dies cannot reach.

The Bulge Buster Kit (UPC 734307904876) includes the essential components you need to set up this operation:

• Extension Sleeve: This component threads into your reloading press and holds the appropriate Lee Factory Crimp Die (carbide version), which contains the critical sizing ring.
• Push-Through Punch: This robust punch is designed to push the brass case completely through the die, ensuring thorough resizing of the entire case body, including the typically unsupported area near the rim.
• Catch Container: A convenient container attaches to the bottom of the system to collect the perfectly reformed, bulge-free cases as they exit the die. This keeps your reloading bench tidy and your processed brass organized.
• Complete Instructions: Lee Precision is known for providing clear, concise instructions, ensuring even novice reloaders can set up and use the Bulge Buster effectively.

It’s crucial to understand that the kit itself does not include the die. The Lee Bulge Buster is designed to work in conjunction with a Lee Factory Crimp Die that features a carbide sizing ring. This is a key distinction, as the carbide ring within the Factory Crimp Die is what performs the actual sizing operation. By purchasing the specific Lee Factory Crimp Die for your caliber (e.g., 9mm, .40 S&W, .45 ACP), you can then utilize the Bulge Buster Kit to turn it into a dedicated push-through sizing system.

Optimizing Your Reloading Process with the Bulge Buster

Integrating the Lee Bulge Buster into your reloading routine is straightforward and highly beneficial, especially for high-volume pistol ammunition producers. Here’s a typical workflow:

1. Case Cleaning: As with all brass preparation, start by cleaning your cases. Tumbling or ultrasonic cleaning removes dirt, grime, and firing residue, making the sizing process smoother and extending the life of your dies.
2. Decapping (Optional, but Recommended): While not strictly necessary for the Bulge Buster, decapping cases before full sizing is often preferred, particularly if you use wet tumbling to clean primer pockets.
3. Bulge Busting: Mount the Bulge Buster Extension Sleeve and your carbide Factory Crimp Die (for the correct caliber) into your single-stage reloading press. Place a case into the shell holder, and cycle the press, allowing the push-through punch to drive the case completely through the die. The perfectly sized case will drop into the catch container.
4. Traditional Sizing/Priming/Charging/Seating: Once the cases are bulge-free, they can be processed like any other perfectly sized case using your standard reloading dies (e.g., expander die, powder drop, bullet seating die, and even the Factory Crimp Die for its crimping function, if desired, in a separate station).

This specialized processing step ensures that even the most stubborn bulges are removed, restoring the case to SAAMI specifications and allowing it to properly chamber in any firearm chambered for that cartridge.
