Reloading your ammunition offers a significant advantage, granting you the ability to tailor your loads precisely to your rifle and the game you intend to pursue. It allows you to optimize performance, control recoil, and potentially save money in the long run. The information presented here will equip you with the knowledge to embark on your reloading journey, building safe and effective loads for your 350 Remington Magnum.
Understanding the 350 Remington Magnum
Before diving into the specifics of load data, it’s crucial to understand the fundamental characteristics of the 350 Remington Magnum.
The genesis of the 350 Remington Magnum can be traced back to the late nineteen sixties, with its introduction designed to capitalize on the popularity of short-action rifles. Its compact design allowed for the creation of a potent cartridge within a manageable action size.
The dimensions of the 350 Remington Magnum are significant factors in understanding its performance. The cartridge case typically measures around two point seventy-three inches in length. The bullet diameter is a critical feature, usually measuring point three hundred fifty-seven inches. This diameter is ideally suited for a wide range of bullet weights, making the cartridge remarkably versatile. A rifle with a barrel twist rate of one in twelve inches is often considered optimal for achieving good stability with typical bullet weights used in the 350 Remington Magnum.
The 350 Remington Magnum offers distinct advantages for the hunter. Its impressive energy delivery, coupled with its relatively flat trajectory, allows for accurate shots at medium to long ranges. This combination of power and accuracy makes it a particularly suitable choice for hunting big game animals.
However, there are also considerations. The 350 Remington Magnum, with its high energy output, can produce noticeable recoil. This is a factor that shooters must consider when selecting their rifle and practicing for consistent accuracy. Furthermore, the high pressures generated within the cartridge can influence barrel life, a consideration to bear in mind when using the cartridge extensively.
Safety First: Essential Reloading Precautions
The reloading process, while rewarding, demands utmost attention to safety. The following precautions should be considered as the cornerstone of your reloading practices.
Always prioritize the use of appropriate safety gear. This includes eye protection, such as safety glasses or goggles, to shield your eyes from potential hazards. Gloves, particularly those that offer good dexterity and grip, are recommended to protect your hands during handling.
The quality of the components you use directly impacts both safety and performance. Always opt for reputable brands when selecting brass cases, primers, bullets, and propellants. Check the integrity of each component meticulously, and never compromise on quality.
Properly calibrated reloading equipment is indispensable. Regularly check and calibrate your scales, ensuring they measure powder charges accurately. Your powder measure also should be precisely set to dispense consistent amounts of powder.
Begin reloading at the *lowest recommended powder charge* listed in your chosen reloading data. Gradually increase the charge in small increments, monitoring for signs of excessive pressure.
There are specific signs that can alert you to excessive pressure. These include flattened primers, a slight cratering around the primer, a sticky bolt lift, and expanded case heads. If you observe any of these signs, immediately reduce the powder charge.
Carefully inspect your cases before reloading. Look for cracks, dents, and other forms of damage. Trim cases to the correct length, as prescribed by your reloading data, and deburr the case mouths to promote consistent bullet seating.
Ensure the proper storage and handling of all components. Store primers, powders, and loaded ammunition in a cool, dry place away from direct sunlight. Be organized and always maintain strict control over your reloading materials.
Load Data: Powder Selection, Bullet Weight, and Data Charts
A deep understanding of powders and their characteristics is crucial in the quest for optimal 350 Remington Magnum load data.
Certain powders are known for their exceptional performance in the 350 Remington Magnum, often providing the ideal balance of velocity, accuracy, and consistent performance.
Powders can be broadly categorized by their burn rate. Faster-burning powders ignite and produce pressure more quickly, while slower-burning powders have a more gradual pressure curve. Medium-burning powders often provide a good compromise between velocity and pressure. The selection of burn rate impacts the overall performance of the load.
The powder characteristics are a significant factor when selecting a specific powder. Consider how the powder performs in various weather conditions, its consistency from lot to lot, and whether it is well suited for hunting applications.
Bullet Selection
Bullet selection is another critical part of the process. Choosing the appropriate bullet weight and type is a key factor that will directly influence your load’s terminal performance and your rifle’s accuracy.
The 350 Remington Magnum accommodates a wide range of bullet weights. The two hundred grain range is a popular choice, offering a combination of speed and power. Heavier weights such as two hundred twenty-five and two hundred fifty grains are typically preferred for larger game and longer ranges.
Bullet types are also extremely diverse. There are several distinct types of bullets, each with its unique design and performance characteristics. For instance, soft point bullets are known for their controlled expansion and are frequently used in hunting applications. Spitzer bullets are distinguished by their pointed shape, designed for a flatter trajectory. Bonded bullets are engineered to maintain their structural integrity upon impact. Partition bullets feature a divided core for controlled expansion and high weight retention.
The selection of bullets should involve the consideration of manufacturers. Barnes, Hornady, Nosler, Sierra, and Swift are among the leading manufacturers of bullets that are particularly well-suited for the 350 Remington Magnum.

Practical Reloading Tips for the 350 Remington Magnum
With a firm understanding of the fundamentals, the practical aspects of reloading the 350 Remington Magnum can be explored.
The first step is case preparation. This includes trimming the case to the correct length, as indicated by your load data. Case mouths should be chamfered and deburred to provide proper bullet seating.
Using the correct primer is essential. Select the correct type of large rifle primer as specified by your load data. Proper priming tools and methods are essential for consistent and reliable primer seating.
Consistent powder charging is essential for maintaining accuracy. Use a high-quality powder measure to accurately dispense the specified amount of powder. Regularly check and weigh your charges to ensure consistency.
Correct bullet seating depth and crimping (if applicable) are key to optimal performance. Seat bullets to the specified overall length (OAL) provided by your reloading data. A slight crimp, if needed, can promote more consistent performance.
Measure the overall length (OAL) of your loaded rounds accurately. This measurement should be in line with what is recommended in your chosen load data.
Consider crimping techniques. A light roll or taper crimp can be applied to the bullet to secure it in the case and promote consistent ignition and burning.
Testing and Fine-Tuning
Reloading is not just about assembling components, it is a process of development and fine-tuning.
Accurately measure the velocity of your loads. A chronograph is an indispensable tool. Track the velocity results and compare them with the data.
Test your loads at the range and evaluate their accuracy. Start by firing groups at a known distance to assess how well the loads perform in terms of group size.
Adjust your loads to achieve optimal performance. Fine-tune your loads based on the results. Increase or decrease the powder charge in small increments, to achieve the desired balance of velocity and accuracy.
Load development is a process that can lead to the perfect load. The process involves testing various powder charges, bullet types, and other components to find the most accurate and consistent loads for your rifle.
Where to Find Additional Load Data
Reliable sources are vital in the reloading process.
Consult reputable reloading manuals. These manuals offer comprehensive information on a wide range of cartridges, powders, and bullet weights.
Powder manufacturer websites are invaluable resources. These websites will provide load data, as well as other valuable insights.
