Understanding What Makes a 400 Legend Bullet
The 400 Legend cartridge has swiftly become a favorite among hunters, target shooters, and those seeking a powerful, yet manageable, round for various applications. Its popularity stems from its impressive ballistics, relatively low recoil, and versatility across different platforms. But the true potential of the 400 Legend is often unlocked through the practice of reloading, allowing shooters to tailor their ammunition to exact specifications. This process gives you ultimate control over performance, accuracy, and, perhaps most appealingly, cost. Selecting the proper bullets is paramount to achieving these benefits. This guide will delve into the essential aspects of 400 Legend bullets and how to choose the perfect projectile for your reloading endeavors.
At its core, the 400 Legend is designed around a specific bullet diameter, a fundamental characteristic that dictates compatibility and performance. A precise understanding of this factor is critical for successful reloading. The 400 Legend bullet features a consistent diameter, a critical element for any reloader. This consistency facilitates proper chambering and optimal engagement with the rifling within the barrel.
Beyond the core diameter, the weight of the bullet plays a significant role in how the 400 Legend performs. The weight is typically measured in grains, and the range for 400 Legend bullets is fairly broad, offering considerable flexibility. Depending on the application, this can significantly alter trajectory, recoil, and the terminal effects upon impact. Heavier bullets, for example, tend to exhibit higher sectional density, often leading to greater penetration. Lighter bullets often translate to flatter trajectories, making them more suitable for longer-range shots.
Furthermore, how the bullet is constructed drastically alters its performance and suitability for various uses. The design and materials used in the bullet’s build profoundly influence how it expands upon impact, how much energy is transferred, and the resulting wound channel. Several key designs are commonly available:
Full Metal Jacket (FMJ)
These bullets encase a lead core within a copper jacket, leaving the lead core exposed at the base. FMJs are generally inexpensive and are ideal for target shooting and plinking. They are reliable and offer good accuracy, but they typically do not expand upon impact, resulting in less dramatic terminal performance. This lack of expansion can be an advantage in situations where deep penetration is critical, such as in certain controlled ranges where over-penetration is a concern.
Jacketed Hollow Point (JHP)
JHPs feature a hollow cavity in the nose, designed to initiate rapid expansion upon impact. As the bullet hits the target, the hollow point causes the bullet to deform and “mushroom,” increasing the frontal area and transferring more energy into the target. JHPs are a popular choice for self-defense and hunting, where controlled expansion and maximum energy transfer are desired.
Soft Point (SP)
Soft points are constructed with a lead core exposed at the tip, covered by a jacket, which promotes expansion upon impact. The exposed lead tip encourages the bullet to mushroom outwards, increasing its diameter and releasing energy into the target. This bullet design often combines controlled expansion with good penetration, making it a versatile option for hunting and personal defense.
Specialized Bullet Types
This category encompasses a range of designs, including solid copper bullets, polymer-tipped bullets, and bonded bullets. Solid copper bullets, for example, offer exceptional penetration and weight retention, making them ideal for hunting tough game. Polymer-tipped bullets often feature a plastic tip to promote expansion, improve ballistic coefficient, and initiate expansion upon impact. Bonded bullets, in contrast, have the core bonded to the jacket. This process is essential for ensuring the bullet holds its shape and weight retention during impact, and it maintains penetration depth.
The ballistic coefficient (BC) is a crucial factor, often represented by a numerical value, that helps explain how a bullet resists air resistance as it flies through the air. A higher BC means the bullet is more aerodynamic and can retain its velocity and energy over longer distances. This is especially important when target shooting or hunting at longer ranges, as it contributes to greater accuracy and flatter trajectories. When selecting 400 Legend bullets, you should consider the BC if you plan on engaging targets beyond a few hundred yards.
Sectional Density (SD) is another essential concept. It compares the bullet’s weight to its diameter, which provides an indication of the bullet’s ability to penetrate a target. A higher SD means the bullet will penetrate deeper, assuming all other factors are equal. It is most often used by hunters to select suitable bullets for harvesting game animals, ensuring the shot will penetrate deep enough to reach vital organs.
Selecting the Right 400 Legend Bullets for Your Needs
Choosing the ideal 400 Legend bullet depends entirely on your intended use. This process is a delicate balance of performance needs, with safety considerations in mind.
If you are using your 400 Legend for hunting, the choice of bullet type and weight becomes very important. For smaller game like whitetail deer or coyotes, JHP or SP bullets in the mid-weight range (e.g., 180-210 grains) are often ideal. These bullets provide a good balance of expansion and penetration. If you are targeting larger game like elk or bear, consider using bullets specifically designed for the task, such as bonded bullets or solid copper bullets. These will provide the necessary penetration and expansion for a clean and ethical harvest.
For casual target shooting and plinking, economy is often a primary concern. Full metal jacket (FMJ) bullets offer the most economical option. They are accurate enough for general target practice and are readily available. They are less likely to over-penetrate a backstop and are also less likely to fragment on impact, making them a safer choice for many ranges.
If your 400 Legend is used for self-defense or home defense, then the choice of bullet becomes critical. Jacket Hollow Point (JHP) bullets are a common choice as they provide controlled expansion and maximum energy transfer while minimizing the risk of over-penetration. Another option is bonded bullets, which are designed to maintain their integrity upon impact and promote deep penetration. However, it is important to test different bullet types in your firearm to ensure reliable function and accuracy.
The selection of bullet manufacturers is a personal choice as well. Several reputable companies produce high-quality 400 Legend bullets. The following are some well-regarded manufacturers:
Hornady
Hornady offers a wide variety of 400 Legend bullets, including their XTP (Extreme Terminal Performance) JHP bullets, which are a popular choice for hunting and self-defense.
Sierra
Sierra bullets are known for their exceptional accuracy, making them a favorite among target shooters. They produce a range of 400 Legend bullets suitable for both target shooting and hunting.
Nosler
Nosler’s bullet offerings include their popular AccuBond and Ballistic Tip lines, which are favored for hunting due to their controlled expansion and excellent accuracy.
Barnes
Barnes specializes in solid copper bullets, which offer excellent penetration and weight retention for hunting tough game.

When deciding which bullet to use, make an educated decision by considering the desired terminal performance, the range at which you’ll be shooting, the barrel twist rate of your firearm (this impacts stabilization of certain bullet weights), and any local restrictions on bullet types.
Essential Reloading Considerations
Selecting the right bullet is only one part of the reloading equation. Reloading involves several different components, each of which impacts performance.
Reloading your own brass offers cost benefits, but you must start with proper brass. Ensure the brass is in good condition, without cracks or damage. You can use new brass or pre-fired brass, but both should be thoroughly inspected and cleaned before use.
You must use the correct primers. Large rifle primers are commonly recommended for the 400 Legend. Using a high-quality primer and matching it with the powder and bullet weight will ensure reliable ignition and consistent performance.
The selection of gunpowder is also essential. You should consult reloading manuals to select powders that are appropriate for the 400 Legend. A few powders known to perform well include Hodgdon Lil’Gun, Alliant 300-MP, and Accurate 1680. A powder with a burn rate that’s neither too slow nor too fast will allow for the bullet to achieve its optimal velocity. The correct powder charge is crucial and will influence both velocity and chamber pressure. Always consult reputable reloading manuals for safe powder charge data.
You will also need the right equipment. Basic reloading equipment will include a press, dies (sizing, seating, and crimping dies), a scale for measuring powder charges, and other accessories for case preparation, such as a case trimmer, deburring tools, and a case cleaner.
The Reloading Process and Safety First
Safety should be paramount during the reloading process. Always follow the safety guidelines outlined in your reloading manual. Wear safety glasses and gloves. Only reload in a well-ventilated area, and never smoke near powder or primers. Double-check all powder charges before seating a bullet. Remember, it is always best to start with a lower charge and work your way up.
The basic steps for reloading include:
Case Preparation
This involves cleaning the brass cases, sizing the cases, and trimming them to the correct length. Cleaning removes dirt and debris, ensuring good performance. Sizing brings the cases back to the correct dimensions. Trimming the cases to the correct length ensures consistent neck tension on the bullet, enhancing accuracy.
Priming
The spent primer is removed, and a fresh primer is inserted into the primer pocket.
Powder Charging
The correct amount of powder, measured by a precise scale, is carefully dispensed into each case.
Bullet Seating
The bullet is then seated into the case. Seating depth, the distance the bullet is inserted into the case, is also a crucial factor that can influence accuracy.
Crimping
This process secures the bullet in the case. Not all cartridges require crimping; consult your reloading manual for guidance.
The pursuit of accuracy is a core principle in reloading. Factors that affect accuracy include consistent powder charges, proper bullet seating depth, and quality components. Load testing is important. This involves making several test loads with varying powder charges or seating depths, and then shooting these loads from a stable platform to measure their accuracy.
