Finding the right powder for your 460 Rowland can significantly impact accuracy, velocity, and overall performance. This comprehensive guide explores the best powders for this powerful cartridge, considering factors like load data, pressure, and intended application. We'll delve into various powder types, providing detailed information to help you make an informed decision. Remember always to consult your reloading manual and adhere strictly to its load data. Safety is paramount in reloading.
Understanding the 460 Rowland Cartridge
The 460 Rowland is a potent cartridge, designed for self-defense and hunting applications. Its popularity stems from its ability to deliver impressive stopping power in a manageable platform, often a 1911-style pistol. Because of its high pressures, choosing the right powder is crucial to avoid dangerous over-pressures. This requires careful attention to detail and adherence to established load data.
Key Factors Affecting Powder Choice
Several factors influence the optimal powder choice for your 460 Rowland loads:
- Bullet Weight: Heavier bullets generally require more powder to achieve desired velocities. Lighter bullets may need less, but always consult load data.
- Desired Velocity: Higher velocities demand more powder, but also increase pressure. This is a delicate balance.
- Case Capacity: The 460 Rowland's case capacity dictates the maximum amount of powder that can safely be used. Exceeding this limit is extremely dangerous.
- Powder Type: Different powder types burn at different rates, impacting pressure curves and overall performance.
- Accuracy: The right powder can enhance your accuracy, while an unsuitable choice can lead to inconsistent results.
Top Powder Choices for 460 Rowland
While many powders can be used, several consistently demonstrate excellent performance in the 460 Rowland:
1. Accurate Arms #9
Accurate Arms #9 is a popular choice known for its reliable performance and clean burning characteristics. It's a relatively fast-burning powder, making it suitable for a range of bullet weights. Many reloaders find it provides excellent accuracy and consistent velocities.
- Pros: Clean burning, accurate, widely available.
- Cons: Can be sensitive to variations in case preparation.
2. Alliant Power Pistol
Alliant Power Pistol is another excellent choice, especially for those seeking higher velocities. This is a slightly slower burning powder compared to Accurate Arms #9, and offers good accuracy across multiple bullet weights. It's particularly well-suited for heavier bullets.
- Pros: High velocity potential, good accuracy.
- Cons: Can be more sensitive to temperature variations than some other powders.
3. Hodgdon TiteGroup
Hodgdon TiteGroup, a fine-grained powder, offers good accuracy and metering capabilities. While sometimes used for lower-pressure cartridges, it has proven suitable for the 460 Rowland with certain bullet weights and loads. However, load data must be followed precisely as this powder can be more sensitive to variations.
- Pros: Good metering, consistent accuracy with proper load data.
- Cons: Requires precise measurement, sensitive to load variations.
Comparative Table of Powder Characteristics
| Powder | Burn Rate | Velocity Potential | Accuracy | Metering | Cleanliness |
|---|---|---|---|---|---|
| Accurate Arms #9 | Fast | Moderate | Excellent | Good | Excellent |
| Alliant Power Pistol | Medium | High | Excellent | Good | Good |
| Hodgdon TiteGroup | Medium-Fast | Moderate to High | Excellent | Excellent | Good |
Note: This table provides a general comparison. Actual performance can vary based on specific load data, environmental conditions, and individual firearm characteristics.
Case Studies and Reloading Examples
(Disclaimer: The following examples are for informational purposes only. Always consult your reloading manual for specific load data and never exceed maximum pressure recommendations. Failure to do so can result in serious injury or death.)
Let's consider a hypothetical example:
- Bullet: 200-grain jacketed hollow point (JHP)
- Powder: Accurate Arms #9
- Primer: Appropriate small pistol primer (check your manual!)
- OAL (Overall Cartridge Length): Check your manual for recommended OAL to avoid over-pressure.
You would consult a reliable reloading manual like those published by Accurate Arms, Alliant, or Hodgdon for specific load data for this combination. The manual will provide starting loads and maximum loads, along with pressure readings. Start with the minimum load and work up gradually, meticulously recording your results and closely monitoring pressure signs (bulging cases, excessive recoil).
Safety First: Reloading Responsibilities
Reloading is a rewarding skill, but it demands meticulous attention to safety. Remember these key points:
- Always consult a reputable reloading manual: Never rely on online information alone.
- Start with minimum loads and work up gradually: Never exceed maximum loads.
- Inspect your cases carefully: Discard any damaged cases.
- Wear appropriate safety gear: Eye protection and hearing protection are essential.
- Properly dispose of any misfires or damaged ammunition: Never attempt to modify or reuse.
- Keep your reloading area clean and organized: A cluttered space increases the risk of errors.
The 460 Rowland offers potent performance, but responsible reloading is crucial. By selecting the appropriate powder and following safe reloading practices, you can maximize the potential of this powerful cartridge while ensuring your safety. Remember, safety should always be your top priority.
