Crimped primer pockets are a common problem for reloaders, and using the right tool to remove them is crucial for safe and reliable reloading. This guide delves into the world of crimped primer pocket removers, exploring their types, uses, and how to choose the best one for your needs. We'll also cover essential safety precautions and troubleshooting tips.
Understanding Crimped Primer Pockets
A crimped primer pocket is a primer pocket whose edge has been squeezed inwards, making it difficult or impossible to seat a new primer correctly. This crimping can occur due to various factors, including:
- Factory Over-Crimping: Some ammunition manufacturers crimp primer pockets more tightly than others.
- Repeated Reloading: Each reloading cycle can slightly increase the crimp, leading to problems over time.
- Case Damage: Damage to the case mouth during firing or handling can affect the primer pocket.
Ignoring crimped primer pockets can lead to several serious problems:
- Misaligned Primers: A misaligned primer can cause a squib load (a round that doesn't fully fire), potentially damaging the firearm.
- Primer Failure to Seat: A poorly seated primer can result in a misfire or a delayed ignition.
- Primer Pocket Damage: Attempting to force a primer into a crimped pocket can damage the case.
Types of Crimped Primer Pocket Removers
Several types of crimped primer pocket removers are available, each with its strengths and weaknesses. The best type for you will depend on your reloading volume, budget, and personal preferences.
1. Handheld Reaming Tools:
These tools use a small reamer (a cutting tool) to carefully remove the crimp. They are inexpensive and generally easy to use, making them a popular choice for beginners.
- Pros: Affordable, simple to use.
- Cons: Can be slower than other methods, requires more manual effort, and may require more care to avoid damaging the case. Some require a separate reamer for different sizes.
2. Power-Driven Primer Pocket Reaming Tools:
These tools use an electric drill or similar power source to drive the reaming process. They are significantly faster and more efficient than handheld tools.
- Pros: Fast and efficient, reduces manual labor.
- Cons: More expensive, requires a power source, and there's a slightly higher risk of damaging the case if not used carefully. This type tends to be quite aggressive on the case.
3. Primer Pocket Swaging Tools:
These tools use a die to collapse the crimp inwards, effectively removing the obstruction without removing material. This preserves the primer pocket and strengthens it.
- Pros: Preserves the integrity of the primer pocket, potentially extending case life.
- Cons: Can be more expensive than other methods, may be less efficient for heavily crimped pockets.
4. Professional/Industrial Crimp Removers
Used more commonly in large-scale ammo manufacturing settings, these utilize highly automated systems to quickly and efficiently remove crimps.
- Pros: Highest efficiency, significant cost savings when working on large production runs.
- Cons: Extremely expensive, not practical for home reloading unless dealing with thousands of rounds.
Choosing the Right Crimped Primer Pocket Remover
The best remover for you depends on your needs. Consider these factors:
- Budget: Handheld tools are the most affordable, while power tools are more expensive.
- Reloading Volume: High-volume reloaders will benefit from power-driven tools, while low-volume reloaders might find handheld tools sufficient.
- Case Types: Ensure the tool you choose is compatible with the cartridge cases you are using. Many tools are specific to various sizes.
- Experience Level: Beginners might prefer simpler, handheld tools, while experienced reloaders might opt for more advanced power tools.
Safety Precautions
Always prioritize safety when using any reloading tool. Follow these precautions:
- Wear Safety Glasses: Debris can fly during the reaming process.
- Use Proper Technique: Follow the manufacturer's instructions carefully to avoid damaging the case or injuring yourself.
- Inspect Cases: Regularly check cases for any signs of damage.
- Work in a Well-Ventilated Area: Some reaming tools produce dust.

Conclusion
A crimped primer pocket remover is an essential tool for any serious reloader. Choosing the right tool based on your needs and using it safely will ensure reliable and safe reloading practices. Remember, preventative measures like inspecting cases carefully and avoiding over-crimping during your initial reloading can help minimize the need to use this equipment. Always prioritize safety and follow the manufacturer's instructions for best results.
