Understanding the Roll Crimper’s Purpose
Reloading shotgun shells is a rewarding hobby, allowing enthusiasts to customize their loads for specific purposes, from hunting to competition shooting. Among the crucial steps in this process is crimping – the action of closing the shell after the components have been loaded. While star crimps are common, the timeless elegance and performance benefits of a roll crimp continue to make the 20 Ga Roll Crimper a favorite tool for many reloaders. This guide provides a comprehensive overview of 20 Ga Roll Crimpers, covering everything you need to know to choose the right one, master its use, and achieve consistently excellent results.
The journey into reloading should prioritize safety and precision. A well-executed crimp isn’t just about aesthetics; it’s critical for reliable ignition, consistent shot patterns, and the overall safety of the process. A properly crimped shell ensures the powder burns correctly, the wad and shot stay in place, and the pressure builds as designed, guaranteeing both performance and minimizing the risk of malfunctions. The 20 Ga Roll Crimper, when used correctly, becomes an invaluable asset in achieving these outcomes.
There’s a certain appeal to the smooth, rolled edge of a roll crimped shell. It has a classic look, reminiscent of the way shotgun shells used to be. However, the beauty of a roll crimp goes beyond mere aesthetics. This type of crimp is particularly well-suited for certain loads, especially those using components that may not work as well with a standard star crimp. Roll crimps often provide more space for the shot column and can be easier to work with when using heavy or bulky wads, and can also be more effective at reducing felt recoil.
At its core, a roll crimper is designed to seal the open end of a shotshell after the shot, wad, and powder have been loaded. It operates by rolling the edge of the shell inward and down, creating a smooth, circular closure. This contrasts with a star crimper, which folds the shell’s mouth inwards in a star-shaped pattern.
The function of a roll crimper is elegant in its simplicity. It applies pressure to the lip of the shotshell, curling it around a central mandrel. This curling process seals the shell, securely containing the components inside. The result is a crimp that is both tight enough to maintain the integrity of the load and flexible enough to allow for proper expansion when the shell is fired.
The benefits of roll crimping are many. The design allows for more space inside the shell, which can be particularly helpful when loading specific components. It’s often the preferred method for loads using fiber wads, which can sometimes be difficult to fully close with a star crimp. The finished shell often displays a higher level of uniformity which contributes to its visual appeal.
It’s worth noting that, while the 20 Ga Roll Crimper offers distinct advantages, it may not be the best choice for every reloading scenario. Star crimps tend to be quicker, and modern reloading equipment is often optimized for that style. For mass-producing standard loads, a star crimper might be more efficient. However, for those prioritizing custom loads, historical loads, or seeking a specific level of visual and performance finesse, the 20 Ga Roll Crimper remains a powerful tool.
Exploring Different Types of Roll Crimpers
The world of 20 Ga Roll Crimpers offers a range of options, each with its own set of features and applications. Understanding the different types is essential for choosing the one that best suits your reloading needs and budget.
Manual Roll Crimpers are the entry point for many reloaders. These hand-held or bench-mounted devices offer a straightforward, cost-effective way to achieve a roll crimp. They typically require the user to manually apply pressure, rotating the shell against the crimping head. They offer a great way to start out and are often very portable, allowing for reloading to be done just about anywhere. Because they are manually operated, these are often less expensive than their powered counterparts.
Powered Roll Crimpers represent a step up in terms of speed and convenience. These crimpers utilize an electric motor or other power source to automate the crimping process. This results in faster loading, reduced physical strain, and generally more consistent crimps, making them ideal for reloaders who work with larger quantities of shells. They provide repeatable results and are much less taxing on the reloader’s hands. Because these models are powered, they can be more expensive than a manual model. However, they usually provide more control and customization options, such as different depth settings and more.
Choosing between manual and powered options depends on several factors. Consider your volume of reloading. If you’re only reloading a few shells at a time, a manual crimper might suffice. If you plan to reload hundreds or even thousands of shells, a powered crimper would be a worthwhile investment. Another important factor is the budget. Manual crimpers are generally much more affordable. Finally, your personal preference comes into play. Some reloaders enjoy the hands-on experience of a manual crimper. Others prefer the speed and ease of use offered by a powered model. Both types produce fantastic results, and the ideal choice is the one that best aligns with your reloading style.
Essential Features to Consider
When selecting a 20 Ga Roll Crimper, several key features deserve careful consideration. Paying attention to these details will help you make an informed decision and choose a crimper that meets your specific requirements.
The construction materials of the crimper play a critical role in its durability and longevity. Look for crimpers made from robust materials, such as high-grade steel or aircraft-grade aluminum. These materials will withstand the wear and tear of repeated use and provide years of reliable service. A well-constructed crimper will feel solid and stable when in use.
The design of the crimping head is crucial for achieving a consistent and effective crimp. The head is the component that actually curls the edge of the shell. Consider the shape and size of the rolling head, as well as the material it’s made from. The best designs feature a smooth, precision-ground surface that minimizes friction and promotes a clean, uniform crimp.
Adjustability is a critical feature, particularly for reloaders who work with different shell lengths or powder volumes. Look for a crimper that allows you to adjust the crimping depth, the pressure applied, or both. This adjustability enables you to fine-tune the crimp to match the specific components of your load, resulting in optimal performance.
A 20 Ga Roll Crimper should be easy to operate and comfortable to use. Look for a design that is ergonomically sound, with a handle or other features that provide a secure grip. If it is a bench model, the ability to securely mount it is another thing to consider. A user-friendly crimper will save you time and reduce the risk of errors.
Compatibility is another important factor. Ensure that the crimper is designed to handle the specific shell lengths and types you intend to reload. Some crimpers are designed specifically for 20 gauge shells. Consider also the type of shells, whether paper, plastic, or other materials. Verify that the crimper is compatible with the wad and shot you will be using.
The price of a roll crimper is an important consideration. There is a wide range of prices available. While a higher price tag doesn’t always guarantee superior performance, generally, investing in a quality crimper will result in increased performance and durability. Research the features and capabilities of each crimper and compare them against the price to find the best value for your needs.
Mastering the Craft: How to Roll Crimp
Successfully using a 20 Ga Roll Crimper requires a systematic approach and a steady hand. Following these steps will help you achieve consistent, high-quality crimps every time.
Before you begin, prioritize safety. Always wear eye protection to shield your eyes from potential debris. Work in a well-ventilated area, and keep your work surface clean and organized. Be sure to follow the safety precautions outlined by your specific reloading equipment manufacturer.
Preparing the shotshell is a crucial first step. Begin by priming the shell. Next, carefully add the powder charge as per your reloading data, followed by the wad. Ensure the wad is properly seated on the powder. Next, you can add the shot or other projectiles, carefully measuring out the correct weight, as instructed in your load data.
Now comes the crimping process. Position the shell in the crimper, ensuring it is straight and square. Adjust the crimper to the desired depth and pressure. Some crimpers have markings that indicate the approximate depth; others require a bit of trial and error. Once adjusted, engage the crimping mechanism. If it is a manual model, you will rotate the shell while maintaining pressure. If it is powered, you’ll activate the mechanism.
Carefully examine the crimped shell. The crimp should be smooth and even, without any cracks or bulges. The crimp should be snug enough to hold the components in place but not so tight that it deforms the shell. Make any necessary adjustments to the crimper’s settings to achieve the desired results.
Troubleshooting is part of the process. If the crimp is too loose, it will likely cause powder leakage or failure to fire. Tighten the crimping depth. If the crimp is too tight, it may result in uneven burn and can damage the shell. Lower the crimping depth. If the crimp is uneven, make sure that the shell is correctly positioned in the crimper. By paying attention to the details, any issues can be resolved quickly.
