Understanding Winchester Super Target (WST) Powder

Winchester Super Target, often abbreviated as WST, is a popular choice among reloaders for several reasons. It’s a fine-grained, fast-burning powder designed primarily for target loads in pistol cartridges, particularly 45 ACP. Its consistent burning rate contributes to excellent accuracy, and its relatively clean burning properties help to minimize fouling in your firearm. Understanding its characteristics is the first step toward safe and effective reloading.

Key Characteristics of WST

Fine Granularity: WST’s fine granules allow for precise metering, ensuring consistent powder charges and minimizing velocity variations.
Fast Burning Rate: Its fast burn rate makes it well-suited for cartridges with relatively small case capacities, such as 9mm, .38 Special, and .45 ACP.
Clean Burning: Compared to some other powders, WST produces less residue, contributing to smoother firearm operation and easier cleaning.
Consistent Performance: WST is known for its consistent lot-to-lot performance, reducing the need to constantly adjust your loads.

Applications of Winchester WST

While WST is most commonly used in handgun cartridges, it can also be used in some shotgun loads. Its versatility makes it a popular choice for reloaders who load a variety of cartridges. Here’s a breakdown of its primary applications:

.45 ACP: WST is a top choice for .45 ACP target loads, delivering excellent accuracy and consistent performance.
.38 Special: It’s also well-suited for .38 Special target loads, providing good accuracy and clean burning.
9mm: While not as commonly used as in .45 ACP, WST can be used in 9mm, particularly for lighter target loads.
Shotgun (Target Loads): Some reloaders use WST in light 12-gauge and 20-gauge target loads. Consult reliable reloading manuals for specific data.

The Importance of Reliable Reloading Data

Reloading ammunition involves working with potentially hazardous materials under high pressure. Using incorrect winchester wst reloading data can lead to dangerous consequences, including firearm damage and personal injury. It’s crucial to rely on reputable sources of reloading data and to follow recommended guidelines meticulously.

Sources of Reloading Data

There are several reliable sources of reloading data, including:

Powder Manufacturers’ Websites: Winchester (Hodgdon) provides reloading data for WST powder on their website. This is often the most up-to-date and accurate information.
Reloading Manuals: Reputable reloading manuals from companies like Lyman, Hornady, and Speer contain extensive reloading data for various powders and cartridges.
Online Reloading Databases: Several online databases compile reloading data from various sources. However, it’s essential to verify the data’s accuracy and reliability before using it.

Understanding Reloading Data Tables

Reloading data is typically presented in tables that include the following information:

Cartridge: The specific cartridge for which the data applies (e.g., .45 ACP).
Bullet Weight: The weight of the bullet in grains (e.g., 230 grain).
Bullet Type: The type of bullet (e.g., lead round nose, jacketed hollow point).
Powder: The type of powder (e.g., Winchester WST).
Starting Load: The recommended starting powder charge in grains.
Maximum Load: The maximum recommended powder charge in grains. Never exceed the maximum load.
Velocity: The expected velocity of the bullet in feet per second (fps).
Pressure: The expected pressure of the load in pounds per square inch (psi).
Primer: The type of primer used in the test load.
Case: The type of case used in the test load.
COL (Cartridge Overall Length): The recommended overall length of the loaded cartridge.

Practical Tips for Reloading with Winchester WST

Beyond simply consulting reloading data, there are several practical tips that can help you achieve optimal results with Winchester WST:

Choosing the Right Components

Selecting the right components is crucial for safe and accurate reloading. Here are some considerations:

Bullets: Choose bullets that are appropriate for your cartridge and intended use. Consider bullet weight, type, and construction.
Primers: Use primers that are recommended for your cartridge and powder. Standard primers are typically used with WST.
Cases: Use high-quality cases that are in good condition. Inspect cases for cracks, dents, and other damage before reloading.

Starting Low and Working Up

Always start with the recommended starting load and gradually work up to the maximum load, while carefully monitoring for pressure signs. This allows you to find the optimal load for your firearm and components without exceeding safe pressure limits. Increase powder charges in small increments (e.g., 0.1 grain) and test each load for accuracy and velocity.

Recognizing Pressure Signs

It’s essential to be able to recognize pressure signs, which indicate that a load is generating excessive pressure. Common pressure signs include:

Flattened Primers: Primers that are excessively flattened or show signs of cratering around the firing pin.
Difficult Extraction: Cases that are difficult to extract from the chamber.
Ejector Marks: Shiny marks on the case head caused by the ejector.
Case Head Expansion: Excessive expansion of the case head.
Split Cases: Cases that split or crack.

If you observe any of these pressure signs, immediately stop using that load and reduce the powder charge.

Maintaining Consistency

Consistency is key to achieving accurate and reliable results. Ensure that you are using consistent powder charges, bullet seating depths, and crimp tension. Use a high-quality powder measure and bullet seating die to minimize variations.

The Role of Cartridge Overall Length (COL)

Cartridge Overall Length (COL) is the overall length of the loaded cartridge, measured from the base of the case to the tip of the bullet. COL is a critical factor in reloading, as it affects pressure, velocity, and accuracy. Using an incorrect COL can lead to dangerous pressure spikes or poor performance.

Finding the Optimal COL

Reloading manuals typically provide a recommended COL for each cartridge and bullet combination. However, the optimal COL may vary depending on your firearm and components. It’s essential to determine the maximum COL that will reliably feed and chamber in your firearm. You can do this by using a dummy round (a cartridge without powder or primer) to test the fit in your firearm’s chamber and magazine.

Once you’ve determined the maximum COL, you can experiment with slightly shorter COLs to find the optimal length for accuracy and performance. Be sure to stay within the recommended COL range provided in your reloading data.

Winchester WST in .45 ACP: A Classic Combination

As mentioned earlier, Winchester WST is a particularly popular choice for reloading .45 ACP cartridges. Its consistent performance, clean burning properties, and moderate velocity make it ideal for target shooting and competition.

Typical .45 ACP WST Loads

Here are some typical .45 ACP loads using Winchester WST powder. Always consult a reliable reloading manual or the Winchester website for the most up-to-date and accurate data.

230 grain Lead Round Nose: 4.0 – 4.5 grains of WST
200 grain Lead Semi-Wadcutter: 4.2 – 4.7 grains of WST
185 grain Jacketed Hollow Point: 4.5 – 5.0 grains of WST

These are just examples, and the optimal load for your firearm and components may vary. Always start with the starting load and work up gradually, while monitoring for pressure signs.

Achieving Accuracy with WST in .45 ACP

To achieve optimal accuracy with WST in .45 ACP, pay close attention to the following factors:

Bullet Seating Depth: Experiment with different bullet seating depths to find the optimal COL for your firearm.
Crimp Tension: Apply a consistent crimp to ensure that the bullet is held securely in the case.
Primer Selection: Use high-quality primers that are appropriate for your cartridge and powder.
Firearm Maintenance: Keep your firearm clean and well-maintained to ensure consistent performance.

Safety Precautions When Reloading

Reloading ammunition involves working with potentially hazardous materials and equipment. It’s crucial to follow all safety precautions to prevent accidents and injuries.

Essential Safety Rules

Wear Safety Glasses: Always wear safety glasses to protect your eyes from flying debris.
Work in a Well-Ventilated Area: Reloading can produce dust and fumes that can be harmful to your health. Work in a well-ventilated area to minimize exposure.
No Smoking or Open Flames: Keep smoking materials and open flames away from reloading components.
Store Components Properly: Store powder and primers in a cool, dry place, away from heat and open flames.
Follow Reloading Data: Always follow recommended reloading data and never exceed the maximum load.
Be Attentive and Focused: Avoid distractions while reloading and focus on the task at hand.
