The .32-20 Winchester is a classic cartridge, beloved by many for its versatility and historical significance. Whether you're loading for Cowboy Action Shooting, plinking, or hunting small game, choosing the right powder is crucial for optimal performance and safety. This guide will delve into the best powders for the .32-20, considering various factors to help you make an informed decision.
Understanding Powder Selection for .32-20
Selecting the right powder isn't simply a matter of picking the "strongest" or "fastest." Several key factors need consideration:
- Bullet Weight: Heavier bullets require more powder to achieve adequate velocity. Lighter bullets can be pushed with less powder, potentially achieving higher velocities, but careful load development is essential.
- Case Capacity: The .32-20 case has a relatively small capacity, limiting the amount of powder that can be safely used. Overloading is a serious safety hazard, potentially leading to catastrophic equipment failure.
- Burn Rate: Different powders burn at different rates. A fast-burning powder is ideal for lighter bullets and lower velocities, while a slower powder might be better suited for heavier bullets and higher velocities. Too slow a powder can lead to inconsistent performance and pressure spikes.
- Desired Velocity: Your intended use will dictate the desired velocity. Cowboy Action Shooting generally uses lower velocities, while hunting may require higher velocities for effective terminal performance.
Top Powder Choices for .32-20
Several powders have proven themselves reliable and effective in the .32-20 cartridge. Remember that this information is for guidance only, and you must consult loading manuals from reputable manufacturers such as Hodgdon, Alliant, and IMR for specific load data before attempting to reload ammunition. Never exceed recommended load data.
1. Unique powders
Many reloaders find success using Unique powder for .32-20 loads. Its versatility and relatively mild burn characteristics make it suitable for a wide range of bullet weights and velocities. It's a popular choice for Cowboy Action Shooting due to its ability to produce consistent, reliable performance.
2. Trail Boss
Trail Boss is a very popular choice for low-pressure loads, especially suitable for Cowboy Action Shooting. Its large volume and slow burn rate contribute to reduced recoil and consistent performance. However, it is crucial to only use Trail Boss according to manufacturer specifications, as exceeding recommended loads can be dangerous.
3. Bullseye
Another excellent option for milder loads, Bullseye powder offers good accuracy and is a readily available choice for many reloaders. Similar to Unique, it's suitable for a broader range of bullet weights but may be less ideal for those aiming for significantly higher velocities.
4. Red Dot
Red Dot is a well-known and versatile powder suitable for a variety of pistol cartridges, including the .32-20. It's often chosen for its consistency and accuracy potential. Like other options mentioned, careful adherence to recommended load data is paramount.
The Importance of Load Development
Regardless of the powder you choose, meticulous load development is essential. Start with the minimum recommended load from a reputable loading manual and work your way up gradually, carefully monitoring pressure signs. Using a chronograph is highly recommended to accurately measure velocity and ensure consistency. Consult with experienced reloaders if you're unsure about any aspect of the process.
Conclusion
Choosing the best powder for your .32-20 depends on your specific needs and intended use. The powders mentioned above have proven effective and are widely available, but the key to success lies in safe and responsible reloading practices, coupled with careful load development. Always consult a reputable loading manual and never exceed recommended load data. Remember, safety should always be your top priority when reloading ammunition.
