Why Reload Shotgun Shells?
The satisfying boom of a shotgun, the way it kicks against your shoulder, the tight pattern of shot that can bring down game or smash a clay pigeon – these are the things that make shotgunning such a compelling activity. But buying factory-loaded shells can be a costly endeavor. That’s where the world of shotgun shell reloading comes in, offering a more economical and customizable approach. Among the many techniques available, roll crimping shotgun shells stands out as a method that can deliver excellent results, allowing shooters to tailor their loads to their specific needs and preferences. This guide will delve into the intricacies of roll crimping, equipping you with the knowledge to create your own high-performance shotgun shells.
The Benefits of Control
Reloading shotgun shells isn’t just about saving money; it’s about taking control. You gain the ability to fine-tune your loads, optimizing them for specific purposes, whether that’s hunting, target shooting, or home defense. You can experiment with different shot sizes, powder types, and wad designs to achieve the perfect pattern, recoil, and overall performance.
What is Roll Crimping?
Roll crimping is a specific reloading technique used to seal the top of a shotgun shell. It’s a method of creating a rolled edge, securing the shot and wad inside the hull. Unlike star crimping, which uses multiple folds, roll crimping provides a smooth, cylindrical closure. This method is particularly well-suited for certain types of hulls and offers several advantages that we’ll explore further. The finished product is easily recognizable by its smooth, rolled appearance.
Advantages and Disadvantages
The advantages of roll crimping often make it a favorite for serious reloaders. The smooth edge of a roll crimp can often result in a better seal, leading to more consistent powder burning. This improved seal can contribute to tighter patterns and more reliable performance, especially with certain types of loads. Furthermore, roll crimping is frequently employed with specific hull types and is well-suited for loads that might not perform optimally with star crimping. Ultimately, it’s about achieving the best possible results for your shooting needs.
While roll crimping boasts several benefits, it’s also important to recognize its potential limitations. The equipment requirements are specific to this method, requiring the purchase of a roll crimping tool. Additionally, the overall process can be slightly more time-consuming compared to star crimping, and not all shotgun shell types may be as suitable for roll crimping. Considering both the pros and cons is crucial when choosing your reloading technique.
Required Equipment and Materials
Let’s now delve into the essential equipment and materials you’ll need to embark on your roll crimping journey.
Roll Crimping Tool
First and foremost, you will need a roll crimping tool. These tools come in different forms. Some are hand-held devices designed to be worked manually, while others can be mounted on a bench, often integrated with a reloading press. The hand-held tools are useful for a more basic setup, and bench-mounted tools are more streamlined for a reloading press. You should choose the right one for your needs and space limitations. It’s best to choose one that is robust and built for durability. Quality tools will provide a longer life span and more reliable performance.
Reloading Press (Optional)
A reloading press, while not strictly required, is strongly recommended. The press significantly streamlines the reloading process by providing a stable platform and leverage for various stages, including depriming, priming, and, most importantly, roll crimping. The press also helps keep consistent crimps across all your loaded shells.
Shotgun Shells
Next on the list are the shotgun shells themselves. Not all hulls are ideal for roll crimping. The most common type of hull used for this method is a straight-walled hull. These have a smooth, cylindrical interior, which allows the roll crimping tool to create a neat and uniform seal. Before using any hull, inspect it meticulously. Look for any cracks, bulges, or other signs of damage. Properly prepared hulls are key to safe and consistent reloads.
Primers
You will need to choose components to load your chosen shells. Begin with primers. These are the small, sensitive components that ignite the powder charge. Use only primers specifically designed for reloading, and always handle them with care. Make sure you choose the correct type of primer that is specified in your reloading manual.
Powder
Next, you’ll need the correct powder type. The type and amount of powder are crucial for achieving the desired performance. Reloading manuals will provide detailed data on powder charges for various shell types, shot sizes, and intended purposes. Always use a reliable powder scale to measure the powder accurately. Accurate powder charges are essential for safety and performance.
Wads
The next element in loading the shells is the wad. This is a crucial component, providing a cushion between the powder and the shot, preventing gas leakage, and ensuring the shot stays together for a certain distance before spreading. The right wad is vital for the performance of the load.
Shot
Finally, you’ll need shot. This is the projectile, the little pellets that deliver the pattern. The size and weight of the shot will depend on your intended use. Again, use a reliable method for measuring the correct amount, as specified in your reloading manual.
Additional Tools
Other essential tools and supplies include a precision scale and measuring devices. A powder scale is crucial for accurately weighing your powder charges. Calipers can be helpful for measuring the overall length (OAL) of the finished shells. Safety glasses are non-negotiable and should be worn at all times when reloading. Safety gloves are also a good idea. Always keep your work area clean and organized.
Step-by-Step Instructions: Roll Crimping Process
Now that you have gathered all the necessary equipment and materials, it’s time to move on to the step-by-step instructions for roll crimping your own shotgun shells.
Prioritizing Safety
Before you begin, emphasize safety. Always wear safety glasses and safety gloves throughout the entire process. Reloading can be dangerous if not done correctly. Also, make sure your work area is well-ventilated to avoid inhaling fumes.
Disassembly
Start by taking apart spent shells. This means removing the spent primer. You can use a depriming tool (often part of your reloading press) to push the spent primer out of the hull. After this step, it’s a good idea to clean the hull. This can be done using a hull tumbler. This removes any residue.
Priming
The next step is priming. Insert a new primer into the primer pocket of the shell. Make sure it’s fully seated, flush with the base of the hull. Incorrectly seated primers can cause misfires or other issues. Always double-check the primer seating.
Powder Charging
Now you are ready to add the powder. Carefully measure the correct amount of powder. Be precise and follow the reloading data from your chosen reloading manual. Use the correct measurement tools. Always double-check your powder charge.
Wad Placement
Next, place the wad in the hull. Be sure to use the correct wad for the shell and load. The wad helps to keep the shot in place.
Shot Dispensing
Carefully measure and add the shot into the shell. Follow the reloading manual for the correct load and shot size for your desired use.
Pre-Crimping (Optional)
Some reloaders choose to perform a pre-crimping step before the final roll crimp. This prepares the hull for the roll crimp, making the final crimp more uniform. There are a variety of pre-crimping tools.
Roll Crimping the Shell
Now, it’s time to roll crimp the shell. Position the shell in the roll crimping tool. Adjust the tool to the appropriate depth for the crimp. Gradually and consistently apply pressure, allowing the tool to roll the edge of the hull inward, creating a smooth, cylindrical seal.
Final Inspection
After roll crimping, inspect each loaded shell thoroughly. Check the overall length (OAL) to ensure it’s within the specified range. Make sure the crimp is tight and secure. If the crimp looks loose, you may need to adjust your crimping tool. Properly crimped shells are essential for safe and reliable performance.
Safety Precautions and Best Practices
Reloading involves several crucial safety precautions. Always wear safety glasses and gloves, and work in a well-ventilated area. Handling gunpowder and primers requires care and attention. Never smoke or use open flames near reloading components. Store powders and primers safely, away from heat and moisture. Always keep components separate from each other and in their original containers.
Following Reloading Data
It is critical to understand and adhere to the reloading data provided by reputable sources, such as reloading manuals. These manuals provide precise load recipes, including powder types, wad designs, shot sizes, and specific hull recommendations. Never deviate from these recommendations, and always stay within the specified limits.
Avoiding Mistakes
A common mistake is overloading the shell with too much powder or using the wrong components. This can cause excessive pressures, leading to dangerous situations. Another common issue is improper crimping, which can cause powder leakage or unreliable ignition.
Maintaining a Safe Environment
Maintaining a clean and organized environment is crucial for safe reloading. Keep your work area free from clutter and debris, and always clean up spilled powder or primers immediately.
Troubleshooting and Common Problems
Even experienced reloaders can run into problems. If your crimps are loose or inconsistent, check the setting on your roll crimping tool, or the fit between the hull and the tool. You may need to adjust the depth of the crimp.
Addressing Performance Issues
If your loaded shells are not performing as expected – for example, if you’re experiencing poor patterns or unreliable cycling in your shotgun – consider the following: Ensure you have used the correct wad for the particular load. Check your powder charge, and confirm that it corresponds with the data in your reloading manual.
Conclusion
To summarize the process of roll crimping, it involves disassembling the spent shell, priming the hull, measuring and dispensing powder, seating a wad, dispensing shot, and, finally, crimping the shell using a roll crimping tool.
