Whether you’re a hunter, a competitive shooter, or simply enjoy the sport for recreation, understanding these components can lead to more accurate and consistent results.
Shotgun wads are more than just simple components; they are the unsung heroes of every shotshell. Their primary function is to act as a barrier, guiding the shot charge down the barrel and ensuring the propellant gases are efficiently channeled to propel the shot. The correct wad selection can significantly impact the pattern, range, and overall effectiveness of your shots. Using the wrong wad can lead to inconsistent patterns, gas leaks, barrel damage, and, ultimately, a less-than-satisfactory shooting experience. As a popular choice for both hunting and target shooting, the 20 gauge shotgun benefits greatly from the correct wad choice. This guide aims to provide a deep dive into the world of 20 gauge shotgun wads, equipping you with the knowledge necessary to make informed decisions and improve your shooting.
Before diving into the specifics of 20 gauge wads, it’s essential to understand what these components are. Shotgun wads are the small, often overlooked, but critically important parts inside a shotshell, nestled between the powder and the shot. They are designed to perform a variety of crucial functions, working in concert with the other components like the hull, primer, powder, and shot, to make your shotshells work.
The primary function of a wad is to contain the shot and direct it down the barrel, acting as a barrier that prevents the hot gases produced by the burning propellant from escaping around the shot column. This ensures maximum energy transfer to the shot, maximizing its velocity and range. Moreover, the wads cushion the shot during the firing process, protecting the delicate pellets from being deformed by the extreme acceleration within the barrel. This protection is vital for achieving tight, consistent shot patterns. Without a wad, the shot would be exposed to the direct force of the propellant gases and the barrel, leading to deformation and scattering, resulting in a drastically reduced effective range and pattern quality.
Wads come in various forms, each designed to address specific shooting needs. Understanding these different types and their applications is a crucial first step towards optimizing your shotshells.
Anatomy of a 20 Gauge Wad
A typical 20 gauge wad is constructed from several key components, each designed to perform a specific task. These parts work together in harmony to achieve optimal performance.
At the base of most wads is the obturator, a part that forms a gas seal against the barrel walls, preventing the hot propellant gases from escaping around the shot column. This seal is critical for maintaining consistent velocity and pattern density. The obturator is commonly made of a flexible, heat-resistant plastic material.
Above the obturator is often a shot cup, which is designed to hold and protect the shot pellets. The shot cup prevents the shot from contacting the barrel walls, reducing friction and minimizing shot deformation. The shape and depth of the shot cup can vary depending on the wad type and intended use, affecting how the shot disperses after exiting the barrel.
The section of the wad that provides cushioning is crucial, protecting the shot pellets during acceleration. It’s frequently designed as a corrugated or segmented section that absorbs the shock of firing. The amount of cushioning offered by this section can also influence the pattern tightness, because more cushioning can lead to less pellet deformation.
The wad’s construction materials also play a vital role in its effectiveness. Most modern wads are constructed from specialized plastics formulated for durability and performance. Plastic wads are typically preferred for their reliability, performance, and cost-effectiveness. Other wad materials, like fiber or felt, are still used in specific applications. The choice of material impacts a number of factors, including the wad’s gas sealing abilities, the cushioning effect it provides, and the overall durability.
Types of 20 Gauge Wads
One-Piece Wads
One-piece wads are the most common type used in 20 gauge shotshells. They are molded from a single piece of plastic and designed for general-purpose shooting. These wads typically include a shot cup, a cushion section, and an obturator, all integrated into a single unit. One-piece wads are valued for their simplicity and ease of use.
Two-Piece Wads
Two-piece wads, also known as segmented wads, consist of two separate parts: an obturator and a shot cup. The design allows for greater versatility in wad selection.
Specialty Wads
Specialty wads are engineered for specific purposes. For example, wads designed for slug loads have unique features to accommodate the shape and weight of a single projectile. Steel shot wads often feature thicker walls and are built with tougher materials to protect the barrel and contain the steel shot. These specialized wads help provide the best performance for the intended ammunition.
Choosing the Right 20 Gauge Wad
Factors to Consider
Choosing the right 20 gauge wad is essential for achieving optimal performance. The decision should consider a variety of elements, including the type of shot, shot weight, and shooting purpose.
The type of shot dictates the proper wad choice. Lead shot, the traditional choice, can be used with a wide variety of wads. However, steel, bismuth, and other non-toxic shot materials require specialized wads. These wads are designed with features like thicker walls to protect the barrel and shot cup designs to prevent the harder shot from contacting the barrel.
The weight and size of the shot charge play a crucial role in wad selection. Larger shot charges require a larger wad with a deeper shot cup to accommodate the volume of pellets. Similarly, different shot sizes may benefit from wads with specific cushioning properties to minimize pellet deformation.
It’s always essential to adhere to published reloading data when selecting a wad. Following the manufacturer’s recommended data ensures that the wad is compatible with the powder, hull, and primer combination being used. This helps to maintain the safety and consistency of the shotshells.
Shooting purpose also determines the best wad. For target shooting, wads designed for tight patterns and reduced felt recoil may be preferred. For hunting, the wad choice will depend on the game being pursued.
When it comes to brand comparisons, the offerings can vary widely. Remington, Winchester, and Claybuster offer a diverse range of wads tailored for different applications. The best way to make the right wad selection is to know the intended use and shot type.
Loading with 20 Gauge Wads
