Therefore, you must have a designated reloading area, free from distractions and cross-contamination.

Always wear appropriate personal protective equipment, including safety glasses to protect your eyes from flying debris and gloves to handle potentially hazardous materials. Hearing protection is also crucial to protect your hearing from the loud noise generated during the reloading process.

Another key safety aspect is to carefully follow published reloading data from reputable sources, such as reloading manuals and powder manufacturer websites. These resources provide detailed information on safe powder charges, bullet weights, and other crucial variables. Never deviate from the recommended data, and never exceed the maximum load listed.

Essential Gear: Assembling Your Reloading Arsenal

To begin reloading the 350 Legend, you’ll need to assemble a set of essential tools and equipment. Investing in quality equipment will pay dividends in terms of accuracy, safety, and longevity. Here’s a breakdown of the essential items:

Reloading Press

This is the heart of the reloading operation. It houses the dies and provides the mechanical advantage needed to size, deprime, prime, and seat bullets. Choose a press that is sturdy and reliable, and that allows for easy cartridge changes.

Dies

These are the tools that shape the brass and seat the bullets. You’ll need a set of dies specifically designed for the 350 Legend. A standard set typically includes a sizing die, a seating die, and a crimping die.

Case Trimmer

This tool trims the brass cases to the correct length, ensuring consistent bullet seating depth and proper chambering in your rifle.

Case Prep Tools

Tools like a chamfering tool and a deburring tool are vital for smoothing the case mouth and removing any sharp edges after trimming. This aids in the smooth seating of bullets.

Scale and Powder Measure

A precise scale is necessary for accurately measuring the weight of the powder charges. Both digital and beam scales are available, with digital scales offering faster readings. A powder measure ensures consistent powder charges across all rounds, leading to greater accuracy.

Priming Tool

A priming tool, either press-mounted or hand-held, is used to seat the primers into the primer pockets of the cases.

Calipers

Calipers are essential for measuring the overall length of the loaded rounds, case dimensions, and bullet diameters.

Components: The Building Blocks of Ammunition

Choosing the right components is critical for achieving accurate and reliable reloads. The 350 Legend offers a wide range of choices.

Brass Cases

You can use new or once-fired brass cases. New cases are ready to go, while once-fired cases need to be inspected, cleaned, and re-sized. Ensure the cases are in good condition and free of any damage.

Primers

Primers ignite the powder charge and are available in various types and sizes. Be sure to use the appropriate primer size and type recommended for the 350 Legend. Consult reloading manuals for specific recommendations.

Powder

The selection of powder greatly impacts the performance of your reloads. Different powders have varying burn rates, which affect the velocity, pressure, and overall performance of the cartridge. Consulting reloading manuals, you’ll find recommendations for suitable powders for the 350 Legend. Consider powders known for their accuracy and consistency.

Bullets

A wide variety of bullet weights and styles are available for the 350 Legend. These choices range from lighter bullets for target shooting to heavier bullets optimized for hunting. Bullet types, such as full metal jacket (FMJ), hollow point (HP), and soft point (SP), each have different characteristics suited for various purposes. Consider your intended use when selecting bullets, whether it is for target practice or hunting.

Crimp

Crimping helps secure the bullet in the case, which is particularly important for hunting loads and loads designed for semi-automatic rifles. A crimp also contributes to consistent ignition and velocity. The need and type of crimp (e.g., roll crimp, taper crimp) depend on the bullet type and the reloading die set.

The Reloading Process: Step-by-Step Precision

Reloading involves a series of steps.

Case Preparation

Begin by cleaning the brass cases to remove any dirt or debris. This can be done using a tumbler or a case cleaner. Once the cases are clean, run them through the sizing die, which resizes the cases to the correct dimensions. After sizing, trim the cases to the correct length, and use a chamfering and deburring tool to smooth the case mouth. Finish off case preparation by cleaning the primer pockets. Inspect the cases for any damage or defects. Discard damaged cases.

Priming

Use the priming tool to insert primers into the primer pockets of the cases. Ensure the primers are seated properly, flush with or slightly below the case head.

Powder Charging

Set up the powder measure for the desired powder charge, and weigh each powder charge on the scale to ensure consistency. Carefully pour the measured powder charge into each case. Visually inspect the powder levels in each case to confirm that each case has received the correct amount of powder.

Bullet Seating

Place the bullet on top of the case mouth and use the seating die to seat the bullet to the desired depth. Proper bullet seating depth is critical for accuracy and chambering. Adjust the seating die to achieve the correct overall length (OAL) of the loaded round. Consult reloading manuals for recommended OALs.

Crimping (if applicable)

If using a crimp, adjust the crimping die to apply the desired crimp to the bullet. Ensure the crimp is consistent across all rounds.

Navigating Data: Load Information and Guidance

The most important aspect of reloading is the use of reliable data sources. Always consult reloading manuals and other reputable sources to find recommended load data for the 350 Legend. These sources provide load recipes that include information on powder type, primer type, bullet weight, and powder charge ranges.

Be sure to start with the minimum recommended powder charge and work your way up, in small increments, while carefully monitoring for signs of excessive pressure. Never exceed the maximum load listed.

Factors that can influence load data include case capacity variations, environmental conditions such as temperature and altitude, and firearm differences such as barrel length and twist rate. Always consider these factors when developing loads.

Fine-Tuning and Testing: Optimizing Your Reloads

Once you have created a batch of reloaded ammunition, it’s time to test it at the range to evaluate its performance.

Range Testing

Use a chronograph to measure the velocity of your loads. Consistent velocity is crucial for accuracy. Shoot groups at various distances to assess accuracy.

Pressure Signs

Closely examine the fired cases for signs of excessive pressure. These signs can include flattened primers, ejector marks on the case head, and difficult case extraction. If you observe any of these signs, reduce the powder charge immediately.

Troubleshooting

If you experience any problems, such as failures to fire, sticking cases, or inconsistent velocities, carefully review your reloading process and check for any potential errors. Adjust the powder charge or other variables as needed to improve performance.
