The 0.68 firing pin has become a popular topic of discussion among firearms enthusiasts, especially those working with the 6GT cartridge. This specific combination is praised for its reliable performance and consistent results. However, to fully understand why the 0.68 firing pin is “OK” with the 6GT cartridge, it’s essential to dive deeper into the technical details, practical applications, and overall benefits of this setup.

What is the 0.68 Firing Pin?

The 0.68 firing pin refers to the diameter of the firing pin, which plays a critical role in the ignition of the cartridge. The firing pin strikes the primer of the cartridge, igniting the gunpowder and firing the bullet. The size of the firing pin, particularly in precision shooting, can influence the performance and reliability of the firearm.

A 0.68 firing pin is slightly smaller than standard firing pins, which are typically around 0.75 inches in diameter. This smaller diameter is particularly advantageous in preventing primer flow (also known as cratering), where the primer material flows back into the firing pin hole, which can cause inconsistent ignition or misfires.

Understanding the 6GT Cartridge

The 6GT (6mm GT) cartridge is a relatively new addition to the world of precision shooting. Developed by George Gardner of GA Precision and Tom Jacobs, the 6GT is designed for competitive shooting and long-range accuracy. It offers a flatter trajectory and reduced recoil compared to other cartridges, making it a favorite among precision rifle shooters.

The 6GT cartridge is known for its efficiency, with excellent barrel life and minimal powder usage. This cartridge’s design allows it to perform exceptionally well in various shooting conditions, from target shooting to hunting. It has quickly gained popularity in the precision shooting community for its balance of performance and efficiency.

Why the 0.68 Firing Pin is Ideal for the 6GT Cartridge?

The compatibility between the 0.68 firing pin and the 6GT cartridge is rooted in the need for precision and reliability. Here’s why the 0.68 firing pin works so well with the 6GT:

1. Reduced Primer Flow: One of the main issues shooters face with larger firing pins is primer flow. The 0.68 firing pin minimizes this issue, leading to cleaner strikes on the primer and more consistent ignition. This is especially important in precision shooting, where consistency is key.
2. Increased Durability: The smaller firing pin reduces the wear and tear on the firing pin hole, which can be a concern with higher-pressure cartridges like the 6GT. This means your firearm will likely last longer and require less maintenance.
3. Enhanced Accuracy: Precision shooting demands the highest levels of accuracy. The combination of the 0.68 firing pin and the 6GT cartridge provides a more stable platform for consistent shots. Shooters have reported improved groupings and reduced fliers with this setup.
4. Safety Improvements: By reducing the chances of primer flow, the 0.68 firing pin enhances the overall safety of your firearm. This is crucial in competitive shooting, where any malfunction can be costly or even dangerous.
5. Adaptability: The 0.68 firing pin is versatile and can be adapted to various firearms chambered for the 6GT. This makes it a convenient choice for shooters looking to upgrade their setup without extensive modifications.

Practical Applications: Where the 0.68 Firing Pin and 6GT Cartridge Shine

The combination of the 0.68 firing pin with the 6GT cartridge is not just theoretical; it has practical applications in various shooting disciplines. Here are some scenarios where this setup excels:

1. Precision Rifle Competitions: Competitive shooters who require the utmost accuracy find the 0.68 firing pin and 6GT cartridge combination to be a winning setup. The consistency and reliability allow for better performance in high-pressure situations.
2. Long-Range Shooting: The 6GT’s flat trajectory and the 0.68 firing pin’s precision make this combination ideal for long-range shooting. Shooters can achieve tighter groupings at distances that challenge other cartridges.
3. Hunting: While the 6GT is more commonly associated with target shooting, it can also be effective for hunting. The reduced recoil and improved accuracy from the 0.68 firing pin allow for better shot placement, which is critical when hunting game.
4. Recreational Shooting: Even for those who shoot recreationally, the benefits of the 0.68 firing pin with the 6GT cartridge are clear. The setup provides a smoother, more reliable shooting experience, which can make your time at the range more enjoyable.

Installation and Setup: How to Integrate the 0.68 Firing Pin with Your 6GT Rifle

For those interested in using a 0.68 firing pin with their 6GT rifle, the installation process is relatively straightforward. However, attention to detail is essential to ensure optimal performance.

1. Consult a Professional: While installing a firing pin might seem simple, it’s always recommended to consult with a gunsmith or professional if you’re unfamiliar with the process. This ensures that everything is installed correctly and safely.
2. Check Compatibility: Ensure that your rifle is compatible with a 0.68 firing pin. Most modern precision rifles can accommodate this firing pin size, but it’s always best to verify with the manufacturer.
3. Test and Adjust: After installation, take your rifle to the range and test it thoroughly. Pay attention to the primer strikes and the overall performance of your shots. If necessary, make adjustments to ensure everything is functioning as expected.
4. Regular Maintenance: Even with a high-quality setup like the 0.68 firing pin and 6GT cartridge, regular maintenance is essential. Clean your rifle regularly and inspect the firing pin and other components for any signs of wear.

Common Issues and How to Overcome Them

While the 0.68 firing pin and 6GT combination is highly effective, there are potential issues that shooters should be aware of:

1. Misfires: Although rare, misfires can occur if the firing pin doesn’t strike the primer correctly. This can be mitigated by ensuring proper installation and using high-quality ammunition.
2. Primer Cratering: While the 0.68 firing pin reduces primer flow, some cratering may still occur with certain primers. If this becomes an issue, consider experimenting with different primer brands to find the best fit for your setup.
3. Compatibility Concerns: Not all rifles may be easily adapted to a 0.68 firing pin. Always check with your rifle’s manufacturer or a qualified gunsmith before making modifications.

Personalizing Your Setup: Customizing the 0.68 Firing Pin and 6GT Combination

One of the benefits of using a 0.68 firing pin with a 6GT cartridge is the ability to customize your setup to suit your specific needs. Here are some ways to personalize your firearm:
