Understanding the Fundamental Role of Priming
Reloading ammunition is a rewarding pursuit, offering the satisfaction of crafting your own cartridges. It’s a craft that extends the life of your brass, allows for customized loads, and can provide significant cost savings. At the heart of this process lies a critical step, one that directly impacts the reliability and safety of your reloaded rounds: priming. And for those focused on shotguns, the 12 gauge priming tool becomes an indispensable piece of equipment. This guide delves into the world of these tools, providing everything you need to know to master this crucial aspect of 12 gauge reloading.
Before diving into the tools themselves, it’s essential to grasp the core function of a primer. Essentially, a primer is a small, self-contained explosive charge located at the base of a shotshell. Its purpose is to ignite the propellant, the gunpowder that ultimately propels the shot or slug from the barrel. This seemingly simple component is a critical link in the firing chain, the initial spark that starts the entire process.
The consequences of a faulty primer or an improperly seated one can range from a frustrating misfire to a potentially dangerous malfunction. A primer that is not seated correctly might not be struck hard enough, resulting in a dud. Conversely, a primer that is seated too deeply can be crushed and become unreliable. Damaged primers, whether from improper handling or manufacturing defects, can similarly lead to malfunctions. Furthermore, a primer that’s not seated flush can interfere with the proper closing of the firing pin, increasing the risk of a malfunction. Understanding these risks highlights the importance of a reliable 12 gauge priming tool.
Delving into the Variety of Priming Tool Designs
The market offers a diverse range of 12 gauge priming tools, each catering to different reloading needs and preferences. The choice ultimately depends on your reloading volume, budget, and the level of automation you desire. Let’s explore the primary categories.
Manual Precision: The Hand Priming Tool
Hand priming tools are the entry point for many reloaders, especially those just beginning their journey or those who prefer a more tactile approach. These tools are typically small, portable, and relatively affordable. They function by allowing the reloader to manually insert a primer into the primer pocket of the shotshell. The reloader physically controls the pressure and seating depth.
Hand priming tools typically feature a primer tray or a feeding mechanism, a lever or handle for actuation, and a seating punch. Some models have adjustable features to accommodate different primer sizes. The simplicity of these tools offers a direct connection to the reloading process, letting you feel the pressure and ensure the primer is properly seated. This can be particularly beneficial for beginners as it fosters a greater understanding of the reloading process. However, hand priming tools, while excellent for small batch reloading, are typically slower than bench-mounted or progressive systems. Popular examples include various models from Lyman, Lee Precision, and RCBS.
Steady and Secure: The Bench-Mounted Priming Tool
For reloaders who want increased speed and consistency, the bench-mounted priming tool presents a significant upgrade. These tools are designed to be securely attached to a reloading bench, providing a stable and ergonomic platform for priming. They are generally more robust than hand tools and allow for more precise primer seating.
Bench-mounted tools generally operate with a lever or handle that the reloader actuates, driving a priming arm that presses the primer into the shell. Many models offer fine adjustments for seating depth, allowing reloaders to achieve perfect primer seating every time. The stability and precision of these tools contribute to greater consistency in your reloads. Furthermore, the bench-mounted design often allows for increased leverage, making the process less strenuous, especially during high-volume sessions. Examples of respected bench-mounted priming tools include those from Redding, RCBS, and Hornady.
The High-Volume Approach: Progressive Reloading Machines
For the high-volume reloader, progressive reloading machines offer the ultimate solution for efficiency. These machines are designed to automate multiple stages of the reloading process, including priming, with a single pull of the handle. As the shell moves through the various stations on the machine, a primer is automatically fed and seated.
Progressive machines often use a dedicated priming station, equipped with an automated primer feed system and a mechanism to ensure proper primer seating. These systems can prime shells at incredible speeds, making them the choice for competitive shooters or those who go through large quantities of ammunition. However, progressive reloaders can be significantly more complex to set up and operate than hand or bench-mounted tools. They also come with a higher initial investment. Popular brands offering progressive reloading machines with priming capabilities include Dillon Precision, Hornady, and MEC.
