Understanding Winchester WST Powder
Properties of WST
Winchester Super Target, or WST, is a smokeless powder specifically formulated for shotgun reloading. Its popularity stems from several key attributes that make it a favorite among both target shooters and hunters. The powder is known for its clean-burning characteristics, leaving minimal residue in your shotgun barrel and action, which contributes to its consistent performance shot after shot. This consistency is crucial, as it helps maintain predictable patterns and consistent velocities, key factors for accuracy.
WST’s burn rate is often described as medium, offering versatility in loading various shot weights and applications. The powder provides reliable ignition and efficient energy transfer, leading to excellent ballistic results. This makes it an ideal choice for a variety of 12-gauge applications, from the precision of trap and skeet shooting to the demanding requirements of hunting.
Prioritizing Safety First
Before diving into any load data, we must emphasize the paramount importance of safety. Reloading is a potentially hazardous activity, and the utmost care is necessary to prevent accidents. Always wear appropriate safety glasses, ear protection, and other protective gear throughout the reloading process.
Carefully inspect all your equipment and components. Make sure the powder is the correct type, the primers are fresh, and the hulls are in good condition. Always work in a well-ventilated area.
Understand that load data is a starting point. Never exceed the maximum load recommendations provided in reputable reloading manuals. Overloading can lead to dangerous and even catastrophic failures. If you notice any signs of excessive pressure, such as flattened primers, bulging hulls, or difficult extraction, stop reloading immediately and consult your reloading manual or a qualified gunsmith.
Handle powder with care, avoiding static electricity and open flames. Store powder in a cool, dry place away from heat and sunlight. Always keep it in its original container, clearly labeled.
Reloading is a rewarding pursuit, but it’s not without risk. Approach it with respect, attention to detail, and a commitment to safety.
Essential Components for 12-Gauge Reloading
Choosing the Right Primer is Crucial
Primers are the first link in the chain of ignition. They provide the initial spark that sets off the powder charge. When working with Winchester WST, it’s essential to select the correct primer. Popular choices often include Winchester primers, although other brands such as Federal and Remington also have suitable options. Always reference your reloading manual to determine the recommended primer for your specific load recipe. Using an incorrect primer can significantly impact the pressure and overall performance of your load.
Hull Selection Impacts the Equation
The hull, or shell casing, provides the structural foundation for your shotshell. Different hull types are designed to handle varying pressures, so choosing the right one is vital. Common choices include Winchester AA hulls, known for their durability and consistent performance. Remington STS and Gun Club hulls are also popular options. Each hull type has specific characteristics and requires corresponding load data. Always ensure the load data you’re using is specifically for the hull type you’ve chosen.
The Wad Matters
The wad, a plastic or fiber component, acts as a cushion between the powder and the shot. It also helps to seal the gasses and ensure the shot travels down the barrel in a concentrated pattern. Different wads are designed for different shot weights and hull types. Winchester wads are often paired with Winchester WST, but other reputable brands like Claybuster also provide suitable options. Choosing the wrong wad can lead to poor patterns and potentially unsafe pressure conditions.
Selecting the Right Shot
The choice of shot depends on your intended use. Lead shot is the classic choice for target shooting and hunting. Steel shot is required for hunting waterfowl in many areas due to environmental regulations. Bismuth, tungsten, and other alternatives also exist. Shot size is another crucial factor. Smaller shot sizes (e.g., #7.5 or #8) are typically preferred for target shooting, while larger shot sizes (e.g., #4 or #2) are used for hunting. Always match your shot selection to your wad choice and the intended target or game.
Powder Measurement is Key
You will need a reliable powder scale. Accurate powder measurement is absolutely crucial. Using too much powder can be dangerous, while too little may not provide enough energy for proper function. Be sure to calibrate your scale, and measure the powder charge repeatedly to verify consistency. A powder trickler is a useful tool for fine-tuning the charge.
Winchester WST Load Data (Application Specific)
*Disclaimer: Always start with the minimum powder charge listed in your chosen reloading manual and gradually increase the charge, carefully monitoring for any signs of excessive pressure. Never exceed the maximum load recommended in your manual. This data is for informational purposes only and is not a substitute for consulting a reputable reloading manual and following its guidelines.*
Target Loads: Your Trap and Skeet Arsenal
Target shooting demands consistent, reliable performance. Winchester WST is a great choice for building these kinds of loads. We will discuss a few popular recipes and the nuances of each.
Example for One Ounce Lead Loads:
