10mm Vs 44 Mag Ballistics Chart – Is A 10 Mm More Powerful Than A 44 Magnum?

10mm Vs 44 Mag

10mm vs 44Mag are two favorite cartridges of many professional hunters because of their mighty destructive power.

Both have many features and technology for self-defense and fighting the bad guys. So what is the main difference between 10mm vs. 44 Mag?

In the article below, I’ll go into the in-depth pros and cons of each to help you make your final judgment. Let’s read on to discover!

The Differences Between 10mm Vs 44 Mag 

Size, performance, speed, recoil, and price are specific aspects I choose to compare the 10mm and 44 Mag. These factors will help you see the difference between these two ammo types.

⚙️ Size

The standard diameter of the 10mm bullet is 0.40 inches, about 0.29 inches lower than the 44 Mag version.

Meanwhile, the rim diameter of the 10mm is much smaller than its rival, at 0.425 and 0.514 inches, respectively. This difference in diameter will somewhat affect their ballistic performance.

In terms of length, 44 Mag owns a total length of about 0.35 inches longer than its other rival. Therefore, the number of particles of these two bullets also varies.

With 44 Mag, there are about 180 – 300 grains, while at 10mm, this parameter is only about 150 – 230 grains. This feature is partly related to the ability to shoot and the gun’s performance, so you must consider it carefully.

⚙️ Handgun Options

Both cartridges can be available for a variety of pistols. The 10mm automatic bullet version will usually be made for semi-automatic pistols. Meanwhile, 44 Mag’s best performance is for revolvers.

So, can 10mm be used for revolvers and vice versa?

The answer is yes, but the performance is not perfect. Incompatibility can cause bullets to get stuck inside or deviate quite a bit even if the target is at the closest distance.

⚙️ Performance Stats

Firing performance is often governed by size, intended purpose, and load quality.

For the most objective comparison of ammo performance, I tested three different product pairs.

  • The first pair (JHP 10mm/170-grain bullets and 44 Mag/180 rounds): There is not too much difference in their performance because the bullet sizes are similar.
  • The second pair (XTP 10mm/180 granules with 44 Mag/180 granules): This test has also not yielded exact comparison results for performance because the bullet sizes are similar.
  • Third pair (Barnes VOR-TX 10mm/55 granules and 44 Mag/225 granules): 44 Mag’s performance is superior even with 225 rounds.

Thus, in a larger number of grains, 44 Mag has clearly demonstrated a stronger performance than 10mm.

⚙️ Muzzle Velocity

Velocity is of prime importance, affecting power, accuracy, and more.

In practice, the 10mm’s 1200 fps average speed is still significantly lower than the 40Mag’s 1500 – 1700 fps.

However, in some instances, 10mm is available to provide absolute velocity for the gunner’s rapid-fire requirement. It also contributes to the performance of this version being more explosive than the in-class ones.

In terms of speed, each type will have its strengths. But the 44 Mag is still the preferred choice because of its distance per second.

⚙️ Ballistics

As assessed earlier, 44Mag is a bullet with a more significant muzzle velocity than 10mm. Therefore, it must provide a flatter orbit because it can cover wider distances in less time.

Comparing ballistics details, 44Mag has a ballistic coefficient greater than or equal to 10mm. The larger width combined with the overall weight makes it more dynamic to withstand wind resistance.

Its rapid velocity also makes it simpler and easier to overcome air resistance.

⚙️ Stopping Power

I did a comparison test between 44 Mag/240 grains and 10mm/180 grains in stopping power. The results show that the 40 Mag is consistently excellent and far exceeds the 10mm.

As you know, stopping power includes a lot of small internal variables, including terminal extension, energy, or penetration depth.

The heavier bullet will carry more energy and give a much more perfect firing performance. And 44 Mag is the product with the most specific strengths.

Even so, 10mm is not necessarily a weak cartridge. In a sense, it would be more suitable to be used for self-defense than for combat.

As such, if you’re looking for a high-performance version with absolute stopping power, 44Mag is a more impressive choice.

⚙️ Recoil

Recoil is the amount of energy a gun exerts on the shooter. The heavier versions often come with more robust and more effective force absorption.

From practical experience through many tests, I feel the recoil with 10mm is much larger than 44 Mag. So, if you are not an experienced shooter, you are very likely to be thrown backward or injure your hand at any time.

⚙️ Price

40 Mag is quite popular because it is involved in the production of many reputable companies. Therefore, it is easier to find and has a price that is more friendly to your tight budget.

Meanwhile, 10mm ammo has never been easy to buy. You can only find it at a few significant dealers in a few central states for a lot more expensive.

10mm Vs. 44 Mag: Which One Is better? 

Both have their strengths to suit different uses.

10mm is the perfect choice for personal protection. Meanwhile, 44 Mag is best for hunting, fighting, and chasing big wild animals. The enormous power of this type can be brutal for even experienced shooters to get used to.

If you use it purely for everyday self-defense situations, the 10mm version can be the top of your choice. Its power is reserved for self-defense instead of hunting like the 44Mag version.

With a hunting hobby, I chose the 44 Mag version because the energy and speed it provides are most remarkable. It helps me quickly capture my prey even at quite a distance.

Stability and accuracy are distinct advantages I see from 44 Mg, which is perfect for my practical desires.

Final Words 

Weight, size, speed, power, and cost are different between 10mm vs. 44 Mag. In the above article, I have analyzed the differences between these two versions.

I hope it helps you to get more information about them to make an accurate choice. You should rely on your intended use, not merely the pros and cons.

If you are a big fan of hunting, the 44 Mag version is the perfect one. But, if you are defending yourself, opt for the 10mm version.
