The 45-70 Government cartridge, a venerable round with a rich history, continues to be a favorite among hunters and shooters alike. Its potent stopping power and impressive accuracy make it a formidable choice for large game hunting. Coupled with the Barnes TSX 300-grain bullet, a renowned performer known for its exceptional penetration and expansion, you have a truly effective hunting load. However, crafting safe and accurate ammunition requires careful attention to detail and adherence to proper reloading procedures. This guide provides comprehensive load data for the Barnes TSX 300-grain bullet in the 45-70 Government cartridge, emphasizing safety and accuracy.
Understanding the Barnes TSX 300 Grain Bullet
The Barnes TSX (Triple-Shock X) bullet is a monolithic all-copper projectile designed for exceptional performance on game. Its unique construction ensures consistent expansion and deep penetration, even at longer ranges. Its design minimizes bullet deformation, leading to greater accuracy and more predictable terminal ballistics. This makes it an excellent choice for hunting a wide variety of game, from deer to larger animals.
45-70 Government Cartridge Considerations
Before diving into load data, it's crucial to understand the 45-70's unique characteristics. This cartridge can handle significant pressure, but exceeding safe limits can lead to dangerous consequences, including catastrophic rifle failure. Therefore, using a reliable reloading manual and following its instructions meticulously is non-negotiable. Never exceed the maximum listed pressure.
Factors Affecting Load Data
Several factors influence the optimal load data for your specific setup. These include:
- Rifle Manufacturer and Model: Different rifles have varying chamber dimensions and tolerances. Always consult your rifle's owner's manual for pressure limits and recommended load data.
- Powder Type: Various powders burn at different rates, influencing pressure and velocity. Experimentation with different powders might be necessary to find the best combination for your setup. This should always be done under the supervision of an experienced reloader.
- Primer Type: While the influence is less significant than powder type, the primer type can slightly impact pressure and ignition characteristics.
- Case Capacity: Variations in case capacity between manufacturers can slightly affect pressure.

Safety First: Reloading Best Practices
- Start Low, Work Up: Begin with the minimum powder charge listed in your reloading manual and gradually increase the charge in small increments, carefully monitoring pressure signs.
- Observe Pressure Signs: Keep a close eye on pressure signs, such as flattened primers, excessive case head expansion, or unusual noise or recoil. If you observe any of these, immediately cease loading and reduce the powder charge.
- Accurate Measurements: Use a scale that provides consistent and accurate powder measurements. Improper powder charges are a leading cause of reloading accidents.
- Clean Equipment: Maintain clean and well-lubricated reloading equipment for optimal performance and safety.
- Consult a Reloading Manual: A comprehensive reloading manual is essential. Reputable manufacturers like Hodgdon, Alliant, and others publish manuals that are frequently updated.
- Seek Experienced Guidance: If you are new to reloading, seek guidance from experienced reloaders. Proper training is crucial.
By following these guidelines and conducting thorough research using reliable sources, you can safely load potent and accurate ammunition for your 45-70 using the Barnes TSX 300-grain bullet. Remember that responsible reloading practices are paramount to ensuring both your safety and the successful outcome of your hunting endeavors. Always prioritize safety above all else.
