H4350 vs H4831 Powder – Which One is Best for You?

H4350 vs H4831 Powder – Which One is Best for You?

When it comes to reloading ammunition, selecting the right powder is crucial. Choosing the wrong powder can result in poor performance, inconsistent accuracy, or even dangerous situations. Among the popular powders for reloading, H4350 and H4831 stand out as versatile options that can be used in a wide range of calibers and applications. But which one should you choose? In this article, we’ll compare H4350 and H4831 powders in terms of burn rate, velocity, accuracy, recoil, temperature sensitivity, availability, and other factors, to help you make an informed decision.

Burn rate comparison

The burn rate of a powder determines how fast it ignites and how much pressure it generates. H4350 is considered a medium-fast burning powder, while H4831 is a slower-burning powder. This means that H4350 produces higher pressures in a shorter amount of time, while H4831 generates lower pressures over a longer period.

Velocity comparison

Velocity is a critical factor in determining the trajectory and kinetic energy of a bullet. H4350 is known for providing high velocity and consistent performance in many cartridges, particularly those based on the .308 Winchester case. On the other hand, H4831 is favored by many long-range shooters for its ability to maintain velocity and energy over long distances, as well as its suitability for magnum cartridges.

Accuracy comparison

Accuracy is the ultimate goal of any reloading endeavor. Both H4350 and H4831 powders have reputations for delivering excellent accuracy, but the specific recipe and components used can have a significant impact on the results. Some shooters report better accuracy with H4350, while others prefer H4831 for its stability and consistency.

Recoil comparison

Recoil can affect both accuracy and shooter comfort. H4350 has a reputation for being a softer recoiling powder, making it more pleasant to shoot in rifles with lighter weight or less muzzle brake. H4831, being a slower burning powder, is generally associated with more recoil and is favored by magnum caliber shooters.

Temperature sensitivity comparison

Temperature sensitivity refers to how much a powder’s performance is affected by changes in ambient temperature. Both H4350 and H4831 are considered fairly insensitive to temperature variations compared to some other powders, but some users report that H4350 may be slightly more temperature stable than H4831.

Availability and price comparison

Availability and price are factors that can vary widely depending on your location and vendor. Both H4350 and H4831 are produced by Hodgdon, a well-known and reputable powder manufacturer. However, due to high demand and shortages in recent years, finding either powder can be a challenge, and prices may fluctuate considerably. Generally speaking, H4831 is considered slightly more expensive than H4350.

Applications and calibers

The versatility of H4350 and H4831 powders is one of their greatest strengths. Both powders can be used in a wide range of cartridges and bullet weights, from light varmint loads to heavy big game loads. However, the two powders are better suited to different applications and calibers. H4350 is often favored for medium-sized cartridges, such as .260 Remington, 6.5 Creedmoor, and .270 Winchester, while H4831 is often used in larger mag

num cartridges, such as .300 Winchester Magnum, .338 Lapua, and .375 H&H Magnum.

Load data and recipes

As with any reloading component, using the correct load data and recipes is crucial for safety and performance. Both H4350 and H4831 have extensive load data available from Hodgdon and other sources. It is essential to follow the recommended recipes and start with the lowest possible charge weight, gradually increasing in small increments until the desired velocity and accuracy are achieved.

Safety considerations

Reloading can be a safe and rewarding hobby, but it also requires careful attention to safety practices. Always wear appropriate eye and ear protection, work in a well-ventilated area, and follow the recommended load data. Keep powders and primers stored in cool, dry places away from sources of heat, flame, or moisture.

Storage and handling tips

Proper storage and handling of powders are essential to maintain their performance and safety. Always store powders in their original containers with tightly sealed lids, away from any heat sources or direct sunlight. Do not transfer powders between containers, as this can increase the risk of static electricity and ignition. Use a powder funnel and clean up any spills or excess powder immediately.

User experiences and opinions

While technical data and specifications are essential, it’s also valuable to consider the experiences and opinions of other users. Online forums, social media groups, and shooting clubs can be great sources of information and advice. However, always take individual opinions with a grain of salt and consider the source’s expertise and experience level.


In summary, H4350 and H4831 powders are both versatile and reliable options for reloading a wide range of cartridges and applications. The choice between the two will depend on your specific needs and preferences, such as burn rate, velocity, accuracy, recoil, temperature sensitivity, availability, and price. Be sure to follow proper safety practices and load data when using either powder.
