The 10mm Auto: A Legacy of Power
The 10mm Auto cartridge emerged from the needs of law enforcement, created by the prolific firearms designer, Jeff Cooper, in conjunction with the firearms manufacturing company, Dornaus & Dixon. The 10mm was intended to be a potent semi-automatic handgun round, offering significantly more power than the existing .45 ACP and offering greater capacity compared to most revolvers. It sought to deliver a balance of velocity, energy, and bullet weight, which, in theory, would provide a significant advantage in defensive situations.
One of the key characteristics of the 10mm is its considerable power. It generally boasts a muzzle velocity and energy that far exceed those of the .45 ACP and even some magnum revolver rounds. However, its recoil, due to the higher energy transfer, can be more pronounced than that of smaller calibers, making it potentially less user-friendly, especially for those not accustomed to handling larger caliber handguns. The flat trajectory of the 10mm, combined with its higher velocity, also provides an advantage at longer ranges compared to slower rounds.
The uses of the 10mm are as varied as the individuals who wield it. It’s a popular choice for hunting game animals, including deer and feral hogs. The cartridge’s ability to penetrate deeply and deliver substantial energy transfer makes it a suitable choice for taking down tough animals. The 10mm also finds its place in self-defense, particularly when used by those seeking a powerful sidearm that provides the potential for a decisive outcome in defensive encounters. Many competitive shooters also favor the 10mm, utilizing its accuracy and power to excel in various shooting disciplines.
Understanding Hard Cast Bullets
Before diving into the Grizzly load, let’s discuss the hard cast bullet type, so that you can be fully aware of the ammunition type. Hard cast bullets are a specific type of bullet construction that involves a lead alloy with high antimony content and a high Brinell hardness rating (usually between 18-25 BHN). The resulting bullets are exceptionally resistant to deformation upon impact, making them capable of deep penetration through a variety of materials. The manufacturing process is typically different than traditional jacketed bullets. The lead alloy is cast into molds.
The advantages of hard cast bullets are numerous. The most significant is their ability to penetrate deeply, even through thick hides, bone, or dense tissue. The hard lead composition minimizes deformation upon impact, meaning that the bullet maintains its shape and continues to drive forward, whereas, a softer bullet may deform. This makes them particularly useful in hunting situations where you need the round to reach the vital organs of an animal. The construction also tends to make them ideal in applications where the possibility of passing through a barrier, such as a car door or windshield, is possible.
There are, of course, potential disadvantages. Hard cast bullets are not as prone to expansion as jacketed hollow points (JHP) and are not the ideal design for expansion, which is a hallmark of many self-defense rounds. Additionally, the nature of the material can result in leading (lead residue) building up inside the firearm barrel. This is more of an issue in faster-firing or higher-pressure firearms.

They have built a reputation for producing powerful and reliable loads that cater to a niche of shooters who demand serious performance. This is particularly true of their 10mm offerings, and their hard cast bullets specifically.
This particular load, the Grizzly 10mm 220 grain hard cast, is a testament to their commitment to quality. It features a heavy, grain bullet. The design is a flat nose. It is made from a carefully selected lead alloy, chosen for its exceptional hardness and ability to withstand high velocities and impacts.
The bullet is generally cast into molds that precisely form the desired shape and dimensions. Each bullet is meticulously inspected to ensure that it meets Grizzly’s exacting standards. The design prioritizes penetration and energy transfer, making it a suitable option for those who require serious stopping power. Grizzly’s attention to detail extends to the loading process as well, utilizing high-quality components, propellants, and casings to ensure consistent performance with every shot.
Considering Performance and Ballistics
The performance of the Grizzly 10mm 220 grain hard cast is where things get particularly interesting. The muzzle velocity, the speed at which the bullet leaves the barrel, is of paramount importance. The published values from Grizzly Cartridge Company typically show a muzzle velocity, or velocity at the muzzle, that hovers around the foot per second mark. The exact velocity can vary depending on the barrel length of the firearm and the specific ammunition batch. It’s worth noting that this figure represents the bullet’s starting velocity and will decrease as the bullet travels downrange.
Energy, measured in foot-pounds, is another critical factor. It represents the kinetic energy carried by the bullet. The Grizzly 10mm 220 grain hard cast delivers a substantial amount of energy at the muzzle. This significant amount of energy contributes to the round’s potential for deep penetration and damage upon impact.
Penetration is a key characteristic of the Grizzly round. Given its hard cast design and heavy grain weight, this bullet is designed for outstanding penetration capabilities. Penetration depth will vary depending on the media being tested, such as ballistic gelatin or other materials. Generally, expect the Grizzly round to perform above average compared to many other bullet types in the 10mm auto cartridge category.
Accuracy is the next factor, and it plays a vital role, no matter what the application. The Grizzly round should perform accurately at various ranges. Grouping sizes will depend on various factors, including the specific firearm used, the shooter’s skill, and environmental conditions. With a well-maintained firearm and a competent shooter, the Grizzly round can be quite accurate out to medium ranges.
Recoil is a subject of much discussion. With a heavier grain bullet and high energy, the Grizzly load will create more felt recoil compared to lighter, faster bullets in the 10mm Auto family. While the recoil isn’t unbearable, users should be prepared for a firm push and should practice with the load to ensure they can control their firearm effectively, especially during follow-up shots.
