The .45-70 Government cartridge, a venerable round with a rich history, continues to captivate shooters and reloaders alike. Its power and accuracy make it ideal for hunting large game, while its nostalgic appeal draws many to the range. This guide delves into the specifics of finding, preparing, and utilizing 45-70 reloading brass, ensuring you're well-equipped for successful reloading sessions.
Sourcing Your 45-70 Reloading Brass
Finding quality .45-70 brass is a crucial first step. Several avenues exist, each with its own advantages and disadvantages:
1. New Brass:
Purchasing new brass offers the most consistent quality and longevity. Expect to pay a premium, but the extended lifespan and reduced risk of defects make it a worthwhile investment for serious reloaders. Look for reputable manufacturers known for their high-quality brass.
2. Once-Fired Brass:
This is a popular and economical option. You can often find once-fired brass at gun ranges, online forums dedicated to reloading, or through specialized retailers. However, carefully inspect each piece for damage before using it. Look for dents, cracks, or excessive case head expansion.
3. Range Brass:
Collecting brass from a shooting range can save considerable money, but it necessitates careful sorting and cleaning. Expect a mix of manufacturers and conditions. Be diligent in discarding any brass showing signs of damage.
Preparing Your 45-70 Brass for Reloading
Before reloading, your brass needs thorough preparation:
1. Cleaning:
A clean case is essential for consistent and safe reloading. Use a suitable case cleaning solution and a vibratory tumbler or ultrasonic cleaner for efficient cleaning. Thoroughly dry the brass afterward to prevent corrosion.
2. Inspection:
Meticulously inspect each case for any imperfections. Discard any showing signs of damage – even small cracks can lead to catastrophic failure. Look for:
- Case Head Separation: A critical defect where the case head separates from the body.
- Cracks: Check the case neck, shoulder, and body for cracks.
- Dents: Significant dents can affect case capacity and potentially cause pressure issues.
- Excessive Expansion: Case head expansion beyond acceptable limits indicates excessive pressure during previous firing.
3. Sizing:
Sizing ensures uniform case dimensions for consistent reloading results. Use a full-length sizing die for the first resizing after firing, and consider neck sizing for subsequent reloads to minimize case wear.
4. Trimming:
Case length varies after firing. Use a case trimmer to maintain consistent case length, crucial for reliable feeding and optimal pressure.
Reloading Your 45-70 Brass: Considerations for Success
Reloading .45-70 requires careful attention to detail. Always consult reloading manuals from reputable manufacturers for accurate load data. Never exceed recommended maximum loads. Key aspects to consider include:
- Powder Selection: Choose a powder appropriate for the bullet weight and desired velocity.
- Bullet Selection: A wide variety of bullets are available for the .45-70, ranging from cast lead to jacketed bullets.
- Primer Selection: Use large rifle primers.
- Crimping: Proper crimping ensures the bullet is securely seated and prevents it from moving during recoil.
Conclusion: Mastering 45-70 Reloading
Reloading .45-70 brass offers a rewarding experience for the dedicated shooter. By carefully sourcing, preparing, and reloading your brass, you can consistently produce accurate and powerful ammunition, perfect for hunting or target shooting. Remember that safety is paramount—always adhere to reloading manuals and prioritize accuracy. Consistent attention to detail will lead to successful and enjoyable reloading sessions.
