Safety First: The Foundation of Responsible Reloading
The Core Principle
Before diving into the mechanics, it’s imperative to emphasize the paramount importance of safety. Reloading, by its very nature, involves working with potentially dangerous materials. The uncontrolled explosion of gunpowder, the sharp impact of primers, and the potential for firearms malfunctions necessitate an unwavering commitment to safety. It’s not merely a suggestion; it’s the absolute bedrock upon which all reloading practices are built. Ignoring safety protocols can lead to serious injury or even death.
Protective Gear
Essential protective gear is non-negotiable. Always wear eye protection. Safety glasses designed for firearms use are a must to shield your eyes from flying debris, spent primers, and potential powder spills. Ear protection is equally crucial. Whether you prefer earplugs or earmuffs, protect your hearing from the concussive blast of each shot. Consider wearing gloves, especially when handling primers and powder, to prevent contamination. Loose clothing should be avoided, and it’s advisable to wear clothing that covers as much skin as possible.
Work Environment and Storage
Beyond personal protection, the work environment is critical. Reload in a well-ventilated area to prevent the build-up of harmful fumes from powder and primers. Proper storage of your components is equally essential. Store powder and primers in a cool, dry place, away from direct sunlight and sources of ignition. Never smoke while reloading, and always ensure you have a fully functional fire extinguisher nearby.
Safe Handling Practices
Safe handling of components is paramount. Treat every component with respect. Understand that primers are impact-sensitive; handle them carefully to avoid accidental detonation. Powder can be ignited, so it must be handled with care and stored properly. Adhere rigidly to the reloading data provided in reputable manuals. Overcharging a shotshell with powder can lead to catastrophic failure of the firearm.
The Tools of the Trade: Equipping Your Reloading Bench
The Reloading Press
Successfully reloading 12 gauge shotshells requires a dedicated space and the right tools. The investment in quality equipment is an investment in both safety and precision.
The heart of any reloading setup is the reloading press. Presses come in various types, with single-stage and progressive presses being the most common. A single-stage press is the simplest, performing one operation at a time. This is a good option for beginners, as it provides a more deliberate and controlled approach to the process. Progressive presses, on the other hand, automate the reloading process, performing multiple operations simultaneously. This significantly increases the speed of reloading, making them ideal for shooters who reload large quantities of ammunition. However, they come with a steeper learning curve and can be more complex to operate.
Essential Dies
Dies are essential for shaping and processing the shotshell hull. You’ll need a series of dies to accomplish the different stages of reloading. These often include a sizing die (to resize the hull after firing), a priming die (to insert the primer), a powder charging die (to accurately measure and dispense the powder charge), and a crimping die (to close the shell after loading).
Measurement Tools
Accuracy is critical in reloading, particularly when measuring powder. A reliable powder scale is a must. Digital scales are now the standard and offer the convenience of quick and accurate measurements. However, beam scales, while requiring a bit more skill, are also highly accurate and can be a good option.
Powder Dispenser and Primer Seater
Powder dispensers come in manual and automatic varieties. Manual dispensers are a cost-effective option, requiring you to manually operate the dispenser and carefully measure each powder charge. Automatic dispensers, often attached to progressive presses, automate the dispensing process and greatly increase loading speed.
A primer seating tool is also a critical piece of equipment. Some presses have built-in primer seating capabilities, while others require a separate tool. Ensure you seat primers to the correct depth, as improper seating can lead to misfires or other malfunctions.
Additional Useful Tools and Components
Additional helpful tools include calipers for measuring overall cartridge length (OAL), a shell holder to secure the hull during different stages, and cleaning supplies to keep your equipment functioning smoothly. Consider investing in a reloading block to organize your work, keeping hulls in order during the reloading process.
The Importance of the Reloading Manual
Finally, and perhaps most importantly, you’ll need a high-quality reloading manual. These manuals, from reputable sources such as Hodgdon, Lyman, and others, provide detailed reloading data specific to your components, powder, and the desired performance. They’re the definitive source of information for safe and effective reloading.
Understanding the Building Blocks: Components of a Shotshell
The Shotshell Hull
The 12 gauge shotshell is comprised of several key components, each playing a vital role in its function. Understanding these components is fundamental to successful reloading.
The shotshell hull is the container that holds all the other components. Hulls come in various types, each with its own characteristics. Straight-walled hulls are commonly used in older shotshell designs, while tapered hulls are often found in modern shells. The choice of hull can influence the overall performance of the loaded shell. After firing, the hull undergoes stress and needs to be prepared for reloading. Cleaning, resizing, and inspection are key steps to ensure it’s suitable for reuse. Inspect the hull for cracks, tears, or other damage. Reject any hulls that show signs of deterioration.
The Primer
The primer is the initial igniter, a small but critical component that initiates the chain reaction. It’s a sensitive explosive compound that is struck by the firing pin, creating a spark that ignites the powder. There are various primer types and sizes (such as 209 primers), and it is critical to use the correct primer specified in your reloading data for the powder you’re using. Using the wrong primer can result in inconsistent ignition and unreliable performance.
The Powder
Powder is the propellant that generates the energy required to propel the shot downrange. Several different types of smokeless powder are designed for shotshells. The correct powder for your chosen load is determined by its burn rate, which influences the velocity and pressure generated. Always use the powder specified in your reloading manual for the desired load. Improper powder selection can lead to dangerous pressure spikes. Proper storage is crucial. Store your powder in a cool, dry place, away from extreme temperatures and sources of ignition.
The Wad
The wad is a crucial component that performs multiple functions. It separates the powder charge from the shot, seals the bore to maximize pressure, and often provides some level of cushioning to the shot during acceleration. Wads come in various designs, tailored to different shot types, shot weights, and hull designs. Selecting the correct wad for your desired load is essential for achieving optimal patterns and performance.
The Shot
Shot is the payload – the projectiles that are fired at your target. The material of the shot can influence both the pattern and the effectiveness of the shot. Lead shot is a traditional choice, known for its density and effectiveness. Steel shot is a popular alternative for hunting waterfowl in areas where lead shot is prohibited. Tungsten, bismuth, and other alternative materials offer high density and excellent performance but are often more expensive. The shot size is also critical, influencing the effective range and the pattern density. Shot sizes are measured in numbers, with smaller numbers indicating larger shot (e.g., #7.5, #8, #4, or #6). Choose the appropriate shot size for your intended use.
The Reloading Process: Step-by-Step Instructions
Getting Started
With your safety gear and equipment in place, and a thorough understanding of the components, you’re ready to begin reloading. Here’s a step-by-step guide, using a single-stage press as an example:
First, gather all your components. Ensure you have the correct powder, primers, wads, shot, and empty hulls. Prepare your bench and reloading area, making sure everything is clean and organized. Now, let’s begin the steps.
Hull Preparation
Hull preparation is the initial step. Depending on the condition of the hulls, you might want to clean them to remove any debris or residue. Next, resize the hulls using the appropriate die. This die will resize the hull back to the correct dimensions.
Priming
Priming is the next critical step. Properly seat a new primer using your priming tool or the priming station on your press. Ensure that the primer is fully seated in the primer pocket and flush with the base of the hull.
Powder Charging
Carefully measure the correct powder charge. Refer to your reloading manual for the exact powder weight for your chosen load. Use your powder scale to accurately weigh the powder and then dispense the powder into the prepared hull.
Wad Seating
Now, insert the wad onto the powder column. Ensure the wad is seated properly, making sure it is firmly in place and seated to the correct depth.
Shot Charging and Crimping
Measure and pour the correct amount of shot into the wad. Again, consult your reloading manual for the specific shot weight for your load.
Finally, crimp the hull to seal the shell. This can be done with a roll crimp or a star crimp, depending on the hull and crimping die you are using. Carefully crimp the hull to ensure a secure closure.
Inspection
Once the process is complete, carefully inspect each completed round. Check for proper crimps, the correct overall length (OAL) of the loaded shell, and overall uniformity. It’s better to discard a questionable round than to risk a malfunction.
Reloading Data and Load Development: Fine-Tuning Your Results
Importance of Manuals
Reloading is more than just assembling components; it’s about crafting ammunition that meets your specific needs. Using reloading manuals is not optional, it is mandatory. These resources provide detailed data and guidance, including powder, primer, wad, and shot weight, along with crucial information about pressure and velocity.
Understanding and Using Load Data
Understanding how to read the manual and finding load data for your specific components is vital. Remember that loads are carefully tested, and the data provided represents safe operating parameters.
Load Development Process
Load development involves carefully testing different loads to find the one that best suits your needs. Start by using the minimum recommended load in your reloading manual. Gradually increase the powder charge in small increments, carefully monitoring the results. Never exceed the maximum load listed in the manual.
Optional: Velocity Measurement
Consider investing in a chronograph to measure the velocity of your loads. This will give you valuable data for comparing different loads. It can help you determine how much extra performance you can get out of your loads, as well as identify any problems.
Recognizing Overpressure
Always look for any signs of overpressure. Flattened primers, difficult extraction, or bulged hulls are all warning signs that you should immediately stop loading that particular batch. If these signs occur, disassemble the shells and start again, reducing the powder charge.
Troubleshooting Common Problems: Identifying and Resolving Issues
Failure to Fire
Even with careful attention to detail, problems can occasionally arise when reloading. Knowing how to troubleshoot these issues is essential.
Failure to fire can occur for a variety of reasons. It could be a bad primer, improper primer seating, or insufficient powder. Inspect the primer to see if it has been struck by the firing pin. If it has, the problem may be with the firing mechanism of your shotgun.
Squib Loads
Squib loads occur when a shot charge is not sufficient to exit the barrel. The shot can become lodged in the barrel, creating a dangerous obstruction.
Pressure Issues
High or low pressures can lead to malfunctions or even firearm damage. High pressures can cause the shell to fail. Low pressures can result in poor patterns and reduced range. Always adhere to the load data in your manual.
Crimp Problems
Poor crimps can create several issues. They can cause the shell to fail and create a risk of powder spilling.
Other Issues
There are many other potential reloading issues that you will encounter. Fortunately, with practice, experience, and attention to detail, it is possible to solve most of them.
