In this 10 mm vs .357 Magnum comparison, we will delve into the key aspects of these two well-regarded calibers that have proven themselves over time in terms of ballistics, penetration potential, recoil control, and overall suitability for a variety of purposes.
History of the 10 mm Auto and 357 Magnum
The 10mm Auto cartridge was created in the early 1980s by Jeff Cooper, a famous firearms expert. He wanted a powerful and adaptable round for semi-automatic pistols that would outperform the .45 ACP, which was the standard at the time.
In 1983, the first 10mm Auto pistol, called the Bren Ten, was released. The gun and its cartridge quickly gained attention for their self-defense potential. The FBI even adopted the 10mm Auto in the late 1980s, but later switched to the less powerful .40 S&W because the 10mm Auto's recoil and gun size were too much for some agents.
Even though it's not as popular with law enforcement anymore, the 10mm Auto is still liked by many civilian shooters for its power, accuracy, and flexibility. It's great for self-defense, hunting, and target shooting. Various bullet types and weights are available for different uses, making the 10mm Auto a top choice for those who want a high-performing cartridge.

The .357 Magnum cartridge was created in 1934 by Smith & Wesson and Winchester, with help from firearms expert Elmer Keith. It was designed to be more powerful than the .38 Special, which it's based on, for better performance in law enforcement situations.
During the 1930s, police needed a stronger cartridge to deal with better-armed criminals. The .357 Magnum provided more stopping power and deeper penetration by using a longer case with more gunpowder, leading to higher speed and energy.
Once released, the .357 Magnum became popular with police and regular people alike. It's great for self-defense, hunting, and target shooting because of its power, accuracy, and flexibility. Various bullet types and weights have been made for different uses, keeping the .357 Magnum popular even today.

357 Magnum VS 10mm Auto - Ballistic Characteristics
When comparing the ballistics of the 357 Magnum and the 10mm auto, it's important to consider their respective advantages and applications.
Here is a brief comparison chart for all popular 357 Magnum:
The .357 Magnum Is A Low-Velocity Cartridge That Relies On Mechanical Wounding To Achieve Fast Kills. It Performs Best With Fast-Expanding Hollow Point Bullets That Shed Some Weight To Maximize Energy Transfer. Most Factory Loads Are Designed For Anti-Personal Use Rather Than Hunting, So It's Crucial To Match Bullet Weight And Construction To The Intended Purpose.
At Impact Velocities Of 2000fps And Faster, The .357 Magnum Can Produce Impressive Kills With Hollow Point Projectiles. However, As Impact Velocities Decrease, Wounding Becomes Narrower And May Require Bullets With Deep Skives And Broad Hollow Points For Optimal Effectiveness.
For Hunting, Three Bullet Weights Are Commonly Used:
Popular 10mm auto personal defense rounds and FMJ:
The 10mm Auto is a powerful and versatile cartridge known for its high-energy and flat trajectory. Its ballistic performance offers a balance between power and manageable recoil, making it suitable for various purposes, including self-defense, hunting, and target shooting.
Key characteristics of the 10mm Auto's ballistic performance include:
High-energy levels: The 10mm Auto offers impressive energy levels, ranging from 400 to 800 foot-pounds, depending on bullet weight and load. This makes it effective for stopping threats and hunting medium-sized game.
Flat trajectory: The 10mm Auto has a relatively flat trajectory, allowing for accurate shooting at extended ranges. This is beneficial for hunting and target shooting, as it minimizes bullet drop over distance.
Versatility: The 10mm Auto can be loaded with various bullet weights and types, from 135 to 220 grains, enabling it to be tailored to specific shooting scenarios or target animals.
Penetration: The 10mm Auto offers deep penetration due to its high-energy levels and bullet construction options. This is essential for self-defense and hunting larger or dangerous game.
Manageable recoil: While the 10mm Auto is a powerful cartridge, its recoil is considered manageable for most shooters, especially when compared to other magnum calibers. This allows for faster follow-up shots and better overall control.
Here are some popular bullet grain weights for the 10mm Auto and .357 Magnum cartridges:
- 155 grain
- 165 grain
- 180 grain
- 200 grain
- 110 grain
- 125 grain
- 140 grain
- 158 grain
- 180 grain
These bullet grain weights are commonly available for both cartridges and cater to different applications such as self-defense, hunting, and target shooting. The performance characteristics of each bullet weight can vary depending on the specific load and manufacturer.
Both the 10mm Auto and .357 Magnum have similar muzzle velocities, with the 10mm Auto offering a slightly flatter trajectory over longer distances due to its higher average velocity. This can be advantageous for hunting and long-range target shooting against wild animals.
The muzzle energies of 10mm Auto and .357 Magnum are generally comparable, with both calibers providing significant stopping power.
However, the 10mm Auto can have a slight edge over the .357 Magnum in terms of energy, especially when loaded with heavier bullets
The 10mm Auto typically has a sharper recoil than the .357 Magnum, which can make it more challenging to shoot accurately for some individuals. However, the 10mm Auto's recoil can be managed with practice and proper technique.
10mm feels like a slightly more kick than the 40 SW.
In general, the .357 Magnum produces more recoil than the .40 S&W but can be less than or similar to the 10mm Auto, depending on the circumstances.
When fired from a revolver, the .357 Magnum's recoil can be more pronounced than when shot from a semiautomatic pistol, as revolvers typically have a more direct transfer of energy to the shooter's hand.
The 10mm Auto is known for its deep penetration, making it well-suited for hunting medium-sized game or in situations where barrier penetration is a concern. The .357 Magnum also offers good penetration but may not be as effective as the 10mm Auto in these specific scenarios
The 10mm Auto can be used for personal defense indoors; however, over-penetration is a concern with this powerful round. The risk of over-penetration could lead to unintended damage or injury to others in the vicinity, especially in densely populated or confined spaces.
To minimize the risk of over-penetration with the 10mm Auto, it is recommended to use proper self-defense ammunition, such as jacketed hollow point (JHP) or frangible bullets. These types of bullets are designed to expand upon impact, reducing the likelihood of over-penetration.
Both the 10mm Auto and .357 Magnum offer a wide variety of bullet weights and types, making them versatile calibers for different applications. Shooters can choose from full metal jacket (FMJ), jacketed hollow point (JHP), and other bullet designs depending on their intended use
Based on average ammo cost at the local shops and online stores, here are the costs:
- Personal Defense (JHP): The average price for 10mm Auto jacketed hollow point (JHP) rounds ranges from $0.70 to $1.50 per round (Lucky Gunner, Bulk Cheap Ammo).
- Full Metal Jacket (FMJ): The average price for 10mm Auto FMJ rounds ranges from $0.50 to $1.00 per round (Lucky Gunner, Bulk Cheap Ammo).
- Personal Defense (JHP): The average price for .357 Magnum JHP rounds ranges from $0.80 to $1.60 per round (Lucky Gunner, MidwayUSA).
- Full Metal Jacket (FMJ): The average price for .357 Magnum FMJ rounds ranges from $0.60 to $1.20 per round (Lucky Gunner, MidwayUSA).
