This article provides information to help you find a good load, but reloading involves many variables, and you must understand them. There’s a substantial risk of serious injury or death if this process is not done correctly. Always prioritize safety above all else. Never deviate from established safety protocols, and double-check every step of the reloading process. Proper training, adherence to safety guidelines, and the use of appropriate safety equipment are essential for a positive reloading experience.

Understanding Barnes Bullets

Barnes bullets are designed to function differently from traditional lead-core bullets. Their all-copper construction leads to specific advantages, but also requires a slightly different approach when reloading. Proper load development is critical to maximizing their performance.

Barnes produces several bullet lines, each catering to specific hunting or shooting needs. The TTSX (Triple Shock X) line, for instance, features a streamlined profile and a polymer tip designed to initiate expansion upon impact. The TSX (Triple Shock X) is a similar design but without the polymer tip. The LRX (Long Range X) line is specifically tailored for long-range shooting, with a longer, sleeker profile for improved ballistics. Each design expands by peeling back the petals upon impact creating three cutting edges, which maximizes energy transfer and creates a large wound channel. The nearly complete weight retention ensures deep penetration.

The choice of which bullet to use will depend on the specific application. When hunting, the weight of the bullet and the potential range need to be considered. For target shooting, accuracy is paramount, and experimentation with different bullet weights and powders can help you achieve the best results.

7mm-08 Rifle Considerations

Selecting the correct bullet weight is paramount for obtaining optimal performance in your rifle. The weight of the bullet will directly affect its trajectory, wind drift, and terminal ballistics. As a general guideline, rifles with a faster twist rate will stabilize heavier bullets, whereas rifles with a slower twist rate will function better with lighter bullets. To begin, check the twist rate of your rifle. This information is usually stamped on the barrel, or you can consult the manufacturer’s specifications.

When selecting your bullet, consider the game you intend to hunt. For deer-sized game, a bullet in the 120-140 grain range often works well. For larger game such as elk, a 140-160 grain bullet might be more appropriate. Remember that a heavier bullet generally provides better penetration, while a lighter bullet tends to have a flatter trajectory. Also, ensure that the bullet’s ballistic coefficient (BC) is high enough for the type of range you expect.

Your rifle’s barrel length also plays a crucial role. Longer barrels generally contribute to higher muzzle velocities, increasing the effective range of your 7mm-08 rounds. The ideal barrel length is a matter of personal preference. But longer barrels provide improved ballistics and can better utilize the potential of Barnes bullets. Shorter barrels offer better maneuverability but may result in slightly reduced velocity.

Action type also has a bearing on your reloading process. For example, a bolt-action rifle is the most common action type for the 7mm-08. Consider whether your action is a long action or a short action. Always ensure that the overall cartridge length (OAL) of your loaded rounds is compatible with your rifle’s magazine.

Above all, the key to successful reloading is diligence and precision. Be meticulous about weighing powder charges, measuring case lengths, and verifying all of your data. Use a quality scale, calipers, and other precision measuring tools. The most reliable equipment you can purchase is a good reloading manual. Always follow the instructions in a reputable reloading manual or consult with a qualified gunsmith or experienced reloader.

Powder Selection Considerations

Selecting the right powder is an essential part of the reloading process. The best powder for a particular bullet weight and velocity requirement depends on many factors, including the bullet’s weight, barrel length, and the desired performance characteristics. The 7mm-08 performs well with a wide array of powders. A good starting point is to select a powder that delivers a burn rate that matches the bullet weight. Powders that are known to be suitable for the 7mm-08 are readily available.

Generally, the more efficient a powder, the less the charge weight will be. Use a proper powder measuring device. Follow the manufacturer’s specifications precisely. Don’t assume that because a powder works well in one cartridge that it is suitable for another. Be careful when transitioning between powder types or lots. The powder manufacturer’s data is the best point of reference.

Here are some popular powders that are frequently used in the 7mm-08 Remington:

• Varget: A versatile powder that is well-suited for a variety of bullet weights, especially from 120 to 140 grains.

Reloading Tips and Techniques

Before loading, consider these tips and techniques to make sure you have the most consistent and accurate loads.

Bullet seating depth influences the accuracy and overall performance of your ammunition. Adjusting the seating depth can fine-tune your ammunition to match the specific characteristics of your rifle. The best method is to start with the factory recommended settings and then incrementally test various seating depths. Experimentation is key; however, never seat the bullet in a way that it contacts the lands of your rifle’s rifling.

Case preparation is another crucial step. Trimming your cases to a consistent length ensures consistent neck tension, which is essential for accuracy. Chamfering and deburring the case mouths improve bullet seating and reduce the risk of damage to the bullet. Neck sizing is also an important consideration.

Primers play an important role in the ignition process. Different primers can impact performance. Always start with the primer that is recommended by your reloading manual.

Loading data can provide a good starting point, but every rifle is unique. To fine-tune your loads, it is vital to work up the load carefully. Begin with the starting load and slowly increase the charge in small increments, such as 0.5 grains, while carefully monitoring for signs of pressure. When you find the most accurate load, be sure to record your measurements.

Always examine your spent brass. Look for ejector marks on the case head. A hard bolt lift is a sign of overpressure. If you encounter any of these signs, immediately stop and reduce the powder charge.
