## Understanding the Savage Axis .308 Barrel System
Before diving into specific barrel options, it’s crucial to understand the mechanics of the Savage Axis .308 barrel system. The Axis, like other Savage rifles, utilizes a barrel nut system, which simplifies barrel changes compared to traditional threaded barrels. This system allows for precise headspacing adjustments, making it easier to achieve optimal accuracy.
### Key Components and Considerations
* **Barrel Nut:** The barrel nut is a crucial component that secures the barrel to the receiver. It allows for precise adjustment of the headspace, which is the distance between the bolt face and the cartridge case head. Correct headspace is essential for safe and accurate shooting.
* **Receiver Threads:** The Savage Axis receiver features specific threads that are designed to accept barrels with compatible threads. It’s essential to ensure that any aftermarket barrel you choose has the correct thread specifications.
* **Headspace:** As mentioned earlier, headspace is a critical factor in rifle accuracy and safety. When changing barrels, it’s imperative to check and adjust the headspace to ensure it falls within the acceptable range for the .308 Winchester cartridge. Failure to do so can result in malfunctions, damage to the rifle, or even injury.
* **Barrel Profile and Length:** The barrel profile and length can significantly impact the rifle’s weight, balance, and accuracy. Thicker, heavier barrels tend to be more rigid and can provide improved accuracy, while shorter barrels are more maneuverable. Consider your intended use and shooting style when choosing a barrel profile and length.
### Savage Axis Barrel Thread Pitch and Dimensions
The Savage Axis .308 typically uses a 1-1/16″ x 20 TPI (threads per inch) barrel thread. However, it is always recommended to verify the thread pitch with the barrel manufacturer or a qualified gunsmith before purchasing a new barrel. The tenon length (the threaded portion of the barrel that screws into the receiver) is also a critical dimension to consider. Most aftermarket barrels designed for the Savage Axis will adhere to these specifications. Deviations are possible, especially with custom barrels, so double-checking is vital.
## Compatible Barrel Options for Savage Axis .308

### Caliber Conversion Considerations
While this guide primarily focuses on .308 Winchester barrels, it’s worth noting that the Savage Axis action can be used for caliber conversions. However, this requires careful consideration and may involve additional modifications, such as changing the bolt face or magazine. Always consult with a qualified gunsmith before attempting a caliber conversion.
## Installation Process: A Step-by-Step Guide
Installing a new barrel on a Savage Axis .308 can be a relatively straightforward process, especially with pre-fit barrels. However, it’s essential to follow the correct procedures and use the appropriate tools to ensure a safe and accurate installation. **Warning: Improper installation can be dangerous and may damage your rifle. If you are not comfortable performing this work yourself, it’s highly recommended to seek the services of a qualified gunsmith.**
### Tools Required
* **Action Wrench:** An action wrench is used to hold the receiver securely while removing and installing the barrel.
* **Barrel Nut Wrench:** A barrel nut wrench is specifically designed to fit the Savage barrel nut.
* **Headspace Gauges:** Headspace gauges are essential for checking and adjusting the headspace. You’ll need both a go and no-go gauge for the .308 Winchester cartridge.
* **Torque Wrench:** A torque wrench is used to tighten the barrel nut to the correct specification.
* **Vise:** A vise is used to hold the action wrench securely.
* **Solvent and Cleaning Supplies:** Cleaning supplies are needed to clean the receiver threads and barrel tenon before installation.
### Step-by-Step Installation
1. **Ensure the rifle is unloaded and safe.** Remove the bolt and magazine.
2. **Secure the action in the action wrench.** Place the action wrench in a vise and tighten it securely.
3. **Loosen the barrel nut.** Use the barrel nut wrench to loosen the barrel nut. It may be quite tight, so apply steady pressure.
4. **Remove the old barrel.** Once the barrel nut is loose, you should be able to unscrew the barrel from the receiver by hand.
5. **Clean the receiver threads and barrel tenon.** Use solvent and cleaning supplies to thoroughly clean the receiver threads and the tenon of the new barrel.
6. **Apply grease to the receiver threads and barrel tenon.** This will help prevent galling and ensure smooth installation.
7. **Screw the new barrel into the receiver.** Screw the new barrel into the receiver by hand until it is snug.
8. **Install the barrel nut.** Slide the barrel nut over the barrel and screw it onto the receiver threads.
9. **Tighten the barrel nut.** Use the barrel nut wrench and torque wrench to tighten the barrel nut to the manufacturer’s recommended torque specification (typically around 40-50 ft-lbs, but always consult the barrel manufacturer’s instructions).
10. **Check the headspace.** Use the headspace gauges to check the headspace. Insert the go gauge into the chamber and close the bolt. The bolt should close completely. Then, insert the no-go gauge into the chamber and attempt to close the bolt. The bolt should not close completely. If the headspace is not within the correct range, you will need to adjust the barrel nut until it is.
11. **Reassemble the rifle.** Reinstall the bolt and magazine.
12. **Test fire the rifle.** Test fire the rifle with a few rounds of ammunition to ensure that it is functioning properly. Start with a single round and carefully inspect the cartridge case after firing for any signs of overpressure.
## Performance Expectations and Accuracy Considerations
Upgrading your Savage Axis .308 barrel can significantly improve its accuracy and overall performance. However, it’s essential to have realistic expectations and understand the factors that can influence accuracy.
### Factors Affecting Accuracy
* **Barrel Quality:** The quality of the barrel is the most significant factor affecting accuracy. High-quality barrels are made from premium materials and feature precision rifling, resulting in improved accuracy.
* **Headspace:** As mentioned earlier, correct headspace is crucial for accuracy and safety. Improper headspace can lead to inconsistent accuracy and even malfunctions.
* **Ammunition:** The type of ammunition you use can also significantly impact accuracy. Experiment with different types of ammunition to find what your rifle shoots best.
* **Bedding:** Bedding the action to the stock can improve accuracy by providing a more stable platform for the action.
* **Shooter Skill:** Ultimately, the shooter’s skill is the most important factor affecting accuracy. Practice regularly and work on your shooting technique to improve your accuracy.
### Expected Accuracy Improvements
With a high-quality aftermarket barrel and proper installation, you can expect to see significant improvements in your Savage Axis .308’s accuracy. A well-tuned rifle should be capable of shooting sub-MOA (minute of angle) groups, meaning that it can consistently shoot groups of 1 inch or less at 100 yards. In our experience, many Savage Axis rifles with upgraded barrels can achieve even better accuracy with careful load development.
