Title: How to Make 6.5-06 AI Brass: A Step-by-Step Guide
The 6.5-06 Ackley Improved (AI) cartridge has gained popularity among precision shooters and hunters for its impressive ballistic performance and long-range capabilities. However, due to its relatively niche status, finding ready-made brass for this cartridge can be a challenge. As a result, many enthusiasts choose to create their own 6.5-06 AI brass from existing brass cases. In this article, we will discuss the step-by-step process of making 6.5-06 AI brass and the tools and techniques required.
What is 6.5-06 AI Cartridge?
The 6.5-06 AI is a wildcat cartridge based on the 6.5-06 Springfield case. The “Ackley Improved” designation indicates that the cartridge has been modified to have a steeper shoulder angle and increased case capacity, resulting in improved velocity and performance compared to the original 6.5-06 cartridge. The 6.5-06 AI is known for its excellent long-range ballistics and relatively low recoil, making it a popular choice for competitive shooting and hunting applications.
Steps to Make 6.5-06 AI Brass:
1. Obtain 6.5-06 Springfield Brass:
Start with a batch of 6.5-06 Springfield brass cases, which are readily available from various manufacturers. Ensure that the brass is in good condition, with no significant damage or deformities.
2. Full-Length Resize the Brass:
Using a full-length resizing die and a suitable press, resize the 6.5-06 Springfield brass to the 6.5-06 AI dimensions. This will typically involve pushing the shoulder of the brass farther back and tapering the body to the desired dimensions. Follow the specific instructions provided with your resizing die.
3. Trim the Brass to Length:
After resizing, trim the brass to the correct overall length using a case trimmer. The 6.5-06 AI has specific case length requirements, so precision is crucial at this stage.
4. Chamfer and Deburr the Case Mouth:
Use a chamfer and deburring tool to remove any burrs and create a chamfer on the inside and outside of the case mouth. This ensures smooth bullet seating and proper alignment.
5. Load and Fireform the Brass:
Load the resized and trimmed brass with a reduced powder charge, typically around 85-90% of the maximum load for the 6.5-06 AI. The purpose is to fireform the brass to the chamber of your specific rifle, allowing the case to take on the desired shape. This step should be done with caution and adherence to safe handloading practices.
6. Final Inspection and Annealing:
After fireforming, inspect the brass for any signs of stress or excessive stretching. Annealing the case necks can help restore uniformity and extend the brass’s life.
Tools and Equipment:
– Full-length resizing die
– Case trimmer
– Chamfer and deburring tool
– Reloading press
– Powder scale
– Fireforming load data
– Annealing machine (optional)
In conclusion, making 6.5-06 AI brass from 6.5-06 Springfield cases requires careful attention to detail and the use of proper tools and techniques. By following the steps outlined in this guide, enthusiasts can create high-quality brass that meets the precise specifications of the 6.5-06 AI cartridge. It’s important to emphasize safety and thorough understanding of the handloading process when creating custom brass, and always consult reliable load data sources and manuals. With the right approach, shooters can enjoy the benefits of the 6.5-06 AI cartridge without the limitations of ready-made brass availability.
