Understanding the Problem: Why Cases Bulge in 9mm
The world of 9mm reloading offers a rewarding experience for firearm enthusiasts, allowing for customized ammunition and potential cost savings. However, the process isn’t without its challenges. One persistent hurdle often encountered is the issue of case bulging. These bulged cases, often a result of chamber design variations or the pressures of modern firearms, can hinder reliable reloading and potentially impact the safety of your reloads. Fortunately, there’s a solution designed to address this specific problem: the Lee Bulge Buster.
This article delves into the intricacies of the Lee Bulge Buster, exploring its function, the benefits it offers, and how it can revolutionize your 9mm reloading experience. We’ll examine the causes of case bulging, its potential dangers, and how the Bulge Buster provides a reliable and effective solution to ensure your ammunition performs optimally.
What Causes Case Bulging?
Before exploring the solution, it’s crucial to understand the root cause of the problem. Case bulging in 9mm ammunition isn’t uncommon, and several factors can contribute to this phenomenon.
One of the primary culprits is variations in chamber designs. While all 9mm chambers share a common nominal dimension, slight differences exist between manufacturers. Some firearms, particularly those with “generous” chambers for increased reliability or those designed for easy extraction, may allow the brass case to expand more significantly upon firing. This expansion can lead to a noticeable bulge, primarily at the base of the case.
Another contributing factor can be feeding and extraction issues. A firearm that isn’t functioning perfectly, such as one with an overly aggressive extractor or a faulty feed ramp, can cause damage to the case and result in deformation.
Furthermore, excessive chamber pressure, which can result from using improperly measured powder charges or incorrect bullet weights, can push brass beyond its elastic limits, creating a bulge.
The use of certain chamber designs, sometimes referred to as “Glock-style” chambers or barrels with less case support, can also exacerbate the problem. These designs aim for enhanced reliability by accommodating a wider range of ammunition, but they can leave a greater portion of the case unsupported during firing, leading to increased bulging.
Risks Associated with Bulged Cases
The consequences of bulged cases extend beyond mere cosmetic issues. Cases that are bulged to an excessive degree may have difficulty chambering in certain firearms, especially those with tighter tolerances. This can result in failures to feed, malfunctions, and frustration at the range.
Moreover, bulged cases can compromise the structural integrity of the cartridge. Repeated firing and resizing of bulged cases can stress the brass, increasing the risk of case failure, such as a rupture, during subsequent firing. A case rupture is a serious safety concern, potentially causing injury to the shooter and damage to the firearm.
The impact of bulging cases on the reloading process itself is significant. Attempting to resize bulged cases with standard full-length resizing dies can be a challenging and often frustrating experience. The extra material in the bulge creates resistance, making it difficult to fully size the case. This can lead to stuck cases, bent or damaged dies, and ultimately, wasted time and effort.
In the realm of reloading, accurate bullet seating and crimping become more difficult, affecting accuracy. Cases which are not properly sized can also affect bullet concentricity and lead to issues in your firearm.
Introducing the Lee Bulge Buster: The Solution to Bulged 9mm Cases
The Lee Bulge Buster is a dedicated tool designed to address the problem of bulging 9mm cases directly. It’s an affordable, practical solution that offers a dedicated approach to restoring those cases for safe and effective reloading.
Components and Functionality
The kit typically comprises several key components. The heart of the system is a specialized sizing die, precisely machined to work in tandem with the other components. Included is a robust press, designed specifically for use with the Bulge Buster’s unique sizing process. The kit also contains a case pusher, a critical part that helps force the case through the die, and a shell holder or adapter specific to 9mm cases. The components are typically made from high-quality materials for durability and longevity, with the die usually crafted from hardened steel.
The Lee Bulge Buster functions differently than traditional full-length resizing dies. Instead of attempting to reshape the entire case from the outside, the Bulge Buster utilizes a unique internal sizing process. The case is carefully pushed through a precisely sized opening within the die. This effectively squeezes the bulged portion of the case back to its original dimensions, eliminating the bulge and restoring the case’s structural integrity.
The operating mechanism is simple yet effective. You insert the 9mm case into the die, which is usually held in the included press. Then, the case pusher is employed to force the case completely through the die from the bottom to the top. This action squeezes the excess brass from the case, reducing the bulge. The process works in a single pass, making it easy to use.
Unlike traditional resizing dies, the Lee Bulge Buster specifically targets the bulged portion of the case, making it an efficient and effective solution for cases that have experienced chamber expansion. This targeted approach minimizes stress on the brass, prolonging its lifespan and ensuring that your reloads function safely and reliably.

Mastering the Lee Bulge Buster: A Step-by-Step Guide
Using the Lee Bulge Buster is a straightforward process, but a bit of practice and attention to detail are critical for optimal results.
Setting up the Bulge Buster
Setup on the reloading press typically involves threading the Bulge Buster die into your reloading press. Specific instructions vary depending on the type of press you own, but the general process involves screwing the die into the press body until it contacts the shell holder or adapter. Following this, make sure the press is properly locked.
The Sizing Process
Preparing your cases for the Bulge Buster involves inspection and cleaning. Before sizing, inspect your cases for any obvious defects, such as cracks, splits, or severe damage. Clean the cases to remove dirt, debris, and any remaining residue from previous firings. Dirty cases can scratch the sizing die and can cause difficulty in operation.
While it is not always necessary, lubricating your 9mm cases can make the sizing process easier and prevent stuck cases. If you choose to lubricate, use a dedicated case lubricant and apply it evenly to the case surface. A light coating is usually sufficient.
The core process of the Lee Bulge Buster involves inserting the case, base up, into the shell holder or adapter. Next, insert the case pusher into the top of the die, using your hand or a tool like a hammer, push the case completely through the die. The case will be sized as it is pushed through, removing any bulge.
Inspection and Common Mistakes
After sizing the cases, inspect each one again. Look for any remaining bulges, or any signs of damage. A quick visual inspection can help ensure that each case is correctly sized.
To avoid complications, steer clear of these common mistakes. Over-lubrication can cause cases to get stuck in the die. Always follow the recommended lubrication guidelines.
Another mistake is incorrect setup. Ensure the die is properly threaded into the press and that the shell holder or adapter is correctly aligned. Improper alignment can lead to sizing failures or damage to your cases.
Finally, never skip case inspection. Thoroughly inspect each case before and after sizing to identify any defects or ensure proper sizing. This helps in ensuring that each case is ready for reloading and safe for use.
