The 460 Rowland, a potent cartridge born from the desire for a powerful, yet controllable round in a 1911 platform, has earned a dedicated following among enthusiasts. Its impressive stopping power and relatively manageable recoil make it a compelling choice for self-defense and competition shooting. However, achieving optimal performance requires careful reloading practices. This guide delves into the intricacies of reloading 460 Rowland ammunition, covering everything from case preparation to final loading considerations.
Understanding the 460 Rowland Cartridge
Before diving into the reloading process, it's crucial to understand the cartridge's specifications. The 460 Rowland is a semi-auto pistol cartridge designed to be fired from modified 1911 pistols. Its relatively short case length, when compared to other high-power rounds, contributes to its manageability in a standard-sized pistol frame. This compact design, however, necessitates precision in reloading to ensure optimal and safe operation. Improperly loaded rounds can lead to malfunctions or catastrophic failures.
Essential Reloading Equipment for 460 Rowland
Reloading the 460 Rowland, like any cartridge, requires specialized equipment. Investing in high-quality tools is crucial for accuracy and safety. Here's a list of essential tools:
- Reloading Press: A single-stage press provides the most control, while progressive presses offer faster production for large batches.
- Case Preparation Tools: This includes a case trimmer, case gauge, and potentially a deburring tool to ensure consistent case dimensions.
- Powder Measure: A precise powder measure, whether electronic or manual, is vital for consistent powder charges.
- Bullet Seating Die: This tool carefully seats the bullet to the correct depth, a critical aspect of 460 Rowland reloading.
- Dies: A full set of dies (sizing, powder, bullet seating, and crimp) specifically designed for the 460 Rowland is essential.
- Scale: A digital scale is recommended for accurate powder weighing. Never rely solely on a powder measure without verification.
- Case Lubricant: Lubricating cases before sizing helps reduce friction and prevents case damage.
- Bullet Puller: In case of mistakes or the need to disassemble loaded rounds.
Step-by-Step Guide to Reloading 460 Rowland
This detailed guide outlines the process, emphasizing safety and accuracy:
1. Case Preparation:
- Inspect Cases: Carefully inspect fired cases for any damage like cracks or dents. Discard any damaged cases.
- Deburring: Remove any burrs from the case mouth and primer pocket.
- Sizing: Resize the cases to their original dimensions using a sizing die. Lubricate the cases before sizing.
- Trimming: Trim cases to the correct length using a case trimmer. Inconsistent case lengths can lead to malfunctions.
2. Primer Seating:
- Prime Cases: Use a small, dedicated primer seating tool to carefully seat the primers. Avoid excessively deep seating, which can cause misfires or dangerous pressures.
3. Powder Charging:
- Weigh Powder Charges: This is the most critical step. Accurately weigh each powder charge using a calibrated scale. Never guess or “eyeball” powder charges. Refer to your chosen load data for the appropriate powder charge. Consistency is paramount.
4. Bullet Seating:
- Seat Bullets: Use the bullet seating die to carefully seat the bullets to the specified depth as indicated in your load data. Insufficient seating can lead to bullets falling out, while excessive seating can cause dangerously high pressures.
5. Crimping:
- Crimp Cases: Crimp the case mouth to securely hold the bullet in place. Over-crimping can damage the bullet or case. Under-crimping can lead to bullets becoming loose.
6. Final Inspection:
- Inspect Loaded Rounds: Carefully inspect each loaded round to ensure proper bullet seating, crimp, and overall appearance. Discard any rounds with imperfections. Use a case gauge to confirm proper dimensions.
Choosing the Right Components: Powder, Bullets, and Primers
Selecting the right components is critical for safe and effective 460 Rowland reloading. Use only high-quality components from reputable manufacturers. Always consult published load data from reputable sources like Accurate Arms, Hodgdon, or IMR before beginning. Never substitute load data or deviate from published recommendations.
- Powders: Various powders are suitable for 460 Rowland, but choosing one based on your specific load data and bullet weight is crucial.
- Bullets: Select bullets appropriate for your specific application, considering weight, type (jacketed hollow point, full metal jacket, etc.), and intended use.
- Primers: Use primers designed for pistol cartridges and specified in your load data.
Safety First: A Constant Reminder
Reloading is inherently dangerous if not approached with meticulous care and respect for safety procedures. Always wear safety glasses and hearing protection. Maintain a clean and organized workspace. Never mix different powder types or components. Consult reputable reloading manuals and follow the instructions precisely. Always double-check your work.
Conclusion: Mastering 460 Rowland Reloading
Reloading 460 Rowland ammunition offers the advantage of customizing your rounds for optimal performance and cost savings. However, this process demands precision, attention to detail, and a deep understanding of safety protocols. By adhering to the outlined steps and prioritizing safety, you can enjoy the benefits of reloading this powerful cartridge responsibly and effectively. Remember, responsible reloading practices are paramount.
