Finding reliable load data for your reloading projects is crucial for safety and accuracy. This guide focuses specifically on Berry's 350-grain bullets in the venerable .45-70 Government cartridge. We'll explore various powder options, discuss load development best practices, and emphasize the importance of safety precautions. Remember: Always consult your reloading manual and follow its instructions meticulously. This information is for guidance only and does not replace the need for your own careful load development.
Understanding Berry's 350 Grain Bullets
Berry's Manufacturing produces high-quality, lead-free plated bullets, offering a cost-effective alternative to jacketed bullets. Their 350-grain .45-70 offering is a popular choice for both target shooting and hunting applications. These bullets are known for their accuracy and consistent performance, making them a favorite among many reloaders. However, it's vital to understand that plated bullets have limitations compared to jacketed bullets; they are generally not suitable for high-velocity loads.
Choosing the Right Powder
The selection of powder significantly impacts the performance of your .45-70 loads. Several powders are well-suited for the Berry's 350-grain bullet. Popular choices include (but are not limited to):
- IMR 4198: A versatile and reliable powder offering moderate pressure levels, ideal for plinking and target shooting.
- IMR 3031: Another excellent choice providing moderate pressure and good accuracy with the 350-grain bullet.
- Hodgdon 4198: Similar to IMR 4198, offering comparable results.
- Accurate No. 5744: A slower-burning powder suitable for heavier bullets and longer barrels, providing excellent accuracy at moderate velocities.
- Unique Powder: Offers good performance at slightly higher pressures.
Disclaimer: This list is not exhaustive. Many other powders could be suitable, but thorough research and adherence to published load data are paramount.
Exploring Different Powder Charges
Experimenting with different powder charges within the safe range specified in your reloading manual is crucial for load development. Start at the minimum charge listed and work your way up in small increments (0.1-0.2 grains at a time), carefully noting the results. Pay attention to accuracy, velocity, and pressure signs (excessive pressure signs include flattened primers, excessive case head expansion, or unusually loud reports).
Essential Reloading Equipment and Supplies
Before you begin, ensure you have the necessary reloading equipment and supplies:
- Reloading Press: A single-stage press is sufficient for beginners.
- Dies: A .45-70 sizing die, a powder measure, and a bullet seating die are essential.
- Powder Scale: A precise powder scale is absolutely crucial for safe and accurate reloading.
- Case Gauge: Ensures cases are properly sized.
- Bullet Lubricant: For easier bullet seating.
- Primer Seating Tool: A dedicated tool for safely seating primers.
- Brass Cases: High-quality brass cases are essential for consistent performance.
- Safety Glasses and Hearing Protection: Always prioritize safety.
Step-by-Step Reloading Process (General Overview)
The reloading process generally involves these steps:
- Case Preparation: Clean, inspect, and resize your brass cases.
- Primer Seating: Carefully seat the primers into the resized cases.
- Powder Charging: Accurately measure and dispense the selected powder charge into each case.
- Bullet Seating: Carefully seat the Berry's 350-grain bullet to the desired depth.
- Crimping (if necessary): Crimp the bullet to secure it in place.
Note: Always consult your specific reloading manual for detailed instructions on each step.
Safety First: Crucial Reminders
- Never exceed maximum recommended loads.
- Always wear safety glasses and hearing protection.
- Double-check your powder charges before seating bullets.
- Work in a well-ventilated area.
- Properly dispose of spent primers and brass.
- Store your reloading components safely and securely.
This guide provides a starting point for developing safe and accurate loads using Berry's 350-grain bullets in your .45-70. Remember that responsible reloading practices are paramount. Always prioritize safety and consult multiple reputable reloading manuals before attempting any reloading. Happy and safe shooting!
