Mastering Brass Preparation: The Hornady Lock-N-Load AP Primer Pocket Swage Tool for Flawless Reloading

For every serious reloader, especially those who demand high-volume production and uncompromising quality, dealing with crimped primer pockets is an unavoidable reality. Whether you're processing military surplus brass, range-collected casings, or simply aiming for the most consistent and safe reloads, properly prepared primer pockets are paramount. Without them, seating new primers can be a frustrating, damaging, and even dangerous endeavor. This is where specialized tools like the Hornady Lock-N-Load AP Primer Pocket Swage Tool (MPN: 041217) become indispensable, transforming a laborious bottleneck into a smooth, integrated step in your reloading process.

Are you a reloader who frequently encounters stubborn primer seating, crushed primers, or even bent primer rams when working with specific types of rifle brass? Do you wonder how to efficiently remove military crimps without damaging your valuable cases? If you're a proud owner of a Hornady Lock-N-Load AP progressive press, or considering becoming one, then understanding the profound benefits of this innovative swaging tool is crucial for elevating your reloading game.

Why Proper Primer Pocket Preparation is Non-Negotiable

The primer pocket is the heart of a successful reload. It's the critical cavity that holds the primer securely in place, ensuring reliable ignition. Many factory-loaded cartridges, particularly military and law enforcement ammunition, feature a crimped primer pocket. This crimp serves a vital purpose: to firmly hold the primer in place even under extreme conditions, preventing primer setback or dislodgement during vigorous handling or automatic firearm operation.

However, this factory crimp presents a significant challenge for reloaders. Attempting to seat a new primer into a crimped pocket without removing the crimp will almost certainly lead to:

• Damaged Primers: Primers can deform, crush, or even detonate if forced into a crimped pocket.
• Bent or Broken Reloading Press Components: The extreme force required can damage your primer seating punch, ram, or even the press itself.
• Inconsistent Primer Seating Depth: This can lead to erratic ignition, affecting accuracy and reliability.
• Safety Hazards: An improperly seated primer is a safety risk, potentially leading to misfires, hangfires, or even premature detonation.

This is precisely the problem the Hornady Lock-N-Load AP Primer Pocket Swage Tool (UPC: 090255412178) is designed to solve, offering a clean, efficient, and reliable solution for high-volume brass processing.

What is the Hornady Lock-N-Load AP Primer Pocket Swage Tool?

The Hornady Lock-N-Load AP Primer Pocket Swage Tool is a purpose-built attachment for the Hornady Lock-N-Load AP progressive reloading press. Unlike other methods that might involve reaming or chamfering, swaging works by reforming the primer pocket's crimp from the inside out. This specialized tool pushes the brass outward, effectively ironing out the crimp and returning the primer pocket to its original, unconstricted diameter, ready for a new primer.

This comprehensive kit, identified by Hornady MPN 041217, comes equipped with both small and large primer pocket swage punches and anvils. This ensures versatility, allowing you to process a wide range of popular rifle calibers that commonly feature crimped primers, including:

• .223 Remington (223 Rem)
• 5.56x45mm NATO (5.56 NATO)
• .308 Winchester (308 Win)
• 7.62x51mm NATO (7.62 NATO)

Its design leverages the robust build and mechanical advantage of the Lock-N-Load AP press, making the swaging process seamless and fast, right on the press.

How Does On-Press Swaging Enhance Your Reloading Workflow?

The true genius of the Hornady Lock-N-Load AP Primer Pocket Swage Tool lies in its integration with your progressive press. Instead of being a separate, time-consuming step performed off-press, this tool allows you to swage primer pockets as part of your normal case preparation routine, right at one of the stations on your Lock-N-Load AP press.

Here’s a breakdown of how it integrates and why it’s so efficient:

• Dedicated Station: The swage tool occupies a single die station on your progressive press. Many reloaders integrate it after sizing and decapping, but before priming.
• Simple Setup: Installation is straightforward. The swage punch is typically threaded into a die body, and the appropriate anvil (small or large) is placed on the shellplate, directly beneath the primer pocket of the case.
• Smooth Operation: As the ram moves up, the swage punch enters the primer pocket, and the case pushes down onto the anvil. The precise dimensions of the punch and anvil, coupled with the immense leverage of the progressive press, gently but firmly reform the crimp.
• No Material Removal: Unlike reaming tools that cut away brass, swaging simply reshapes it. This means you retain the maximum possible brass integrity and extend the lifespan of your cases.
• Consistent Results: Each swaged primer pocket is reformed to a consistent diameter, ensuring uniform primer seating tension for every round, which directly contributes to enhanced accuracy and reliability in your reloads.

This integrated approach significantly reduces handling time and eliminates the need for manual, repetitive reaming operations, making your brass processing faster and less fatiguing, especially when dealing with hundreds or thousands of cases.

Frequently Asked Questions about Primer Pocket Swaging

Let’s address some common questions that reloaders often have when considering a primer pocket swaging tool.

What exactly is a primer pocket crimp, and why do I need to remove it?

A primer pocket crimp is a small ring of brass that is pressed into the primer pocket opening, designed to securely hold the primer in place, particularly for ammunition intended for auto-loading firearms or military use. You need to remove it because it obstructs the seating of a new primer, preventing it from seating fully and safely. Trying to force a primer past a crimp can damage the primer, your reloading equipment, or result in an unsafe round.

How can I tell if my brass has a crimped primer pocket?

Look closely at the primer pocket. A crimp will appear as a small, circular ring of brass pressed tightly around the edge of the pocket. Some crimps are subtle, while others are quite distinct. Common types include ring crimps (circular indentation) and stake crimps (small triangular or circular stakes at intervals around the pocket). If you’re unsure, try to seat a decapped primer. If it meets significant resistance almost immediately and won't go in smoothly, it’s likely crimped.

Is swaging better than reaming or chamfering for removing crimps?

Many reloaders prefer swaging for several reasons:

• No Material Loss: Swaging reforms the brass; reaming/chamfering removes material. This preserves the brass integrity and extends case life.
• Consistency: Swaging provides a more consistent primer pocket diameter from case to case, leading to more uniform primer seating tension.
• Cleanliness: Swaging doesn't create brass shavings, eliminating the need for cleaning up debris.
• On-Press Efficiency: Especially with a tool like the Hornady Lock-N-Load AP Swage Tool, the process is integrated into your progressive workflow, saving time.

While reaming works, it's often messier and can potentially remove too much brass if not done carefully, leading to loose primer pockets after multiple reloads.

Can I use the Hornady Lock-N-Load AP Primer Pocket Swage Tool on a single-stage press?

No, this specific tool (MPN 041217) is designed exclusively for the Hornady Lock-N-Load AP progressive reloading press. Its mechanism relies on the specific clearances, shellplate, and leverage system of the AP press.
