Quick History of the 10mm Ammo
The 10mm ammo dates back to about the ’70s when the idea of a flat profiled cartridge first came to light. The major objective was to produce a semi-auto cartridge that could perform similar in ballistics to the .357 and the .44 magnum rounds.
The development of the 10mm auto is attributed to Jeff Cooper and Norma Company. For a second, the 10mm auto saw its few seconds of fame when the FBI adopted it and made it a standard cartridge for their officers. However, these required larger guns which took longer to reload. Moreover, most officers felt queasy handling such large guns, fearing they might shoot someone dead.
Soon, manufacturers took note of the problem and developed a lighter version called Lite rounds. However, the lightweight came with its drawbacks. As a result, the 10mm auto lost half of its power, bringing it down to the modern 40 S&W loads.
In fact, this is how the 40 S&W was developed! The FBI chose for shorter rounds and ended up with what you know as the 40S&W today.
Today, the 10mm auto refers only to a slightly modified version of the original rounds. Subsequently, they pack much more power and penetrate deeper into the flesh.

Which Ammo is Close to the 10mm in Terms of Power?
Usually, manufacturers perform their own ballistics test and make the results public. These results show that the 10mm and the 357 are quite close cousins when it comes to power. You’ll find a standard weight of 180 gr. with a muzzle velocity of around 1100 fps. This makes them perfect for semi-automatic handguns.
Where to Use it?
You won’t often find a cartridge that is as versatile as the 10mm ammo.
- Hunting: With a 10mm ammo handgun by your side, you can take home the biggest of game. I have hunted many bears and deer with a 10mm handgun. So, for those who love to hunt with a handgun, the 10mm auto and the extreme power it provides is definitely a win.
- Self-Defense: On the other hand, you can also use it for self-defense purposes. Those who like to carry around larger guns will find that the 10mm ammo fits right in their requirements.
- Training/Plinking: A few full metal jacket versions of the 10mm auto ammo are available as well. This helps newbies train without worrying about wasting a bunch of money.

What to Consider When Buying 10mm Ammo
The following major factors should be considered when buying 10mm ammo:
- Type of Ammo
Although there are various types of ammo on the market, you should only consider two main types: the full metal jacket and the jacketed hollow point cartridges. The JHP rounds expand when they impact, leaving a larger and deeper wound. This makes them perfect for hunting or self-defense.
On the other hand, the FMJ rounds are more suited for training or plinking since they are cheaper. Plus, you can buy them in bulk.
The weight of the bullet is measured in grains. It can determine the extent of penetration as well as accuracy. However, if the bullet is too heavy, it might result in a larger recoil. So, ensure that the weight is optimal.
- Number of Rounds
If you’re an avid hunter, you might need a box of 50 rounds. For them, I always recommend buying in bulk. This will be a cheaper option for you as well than buying individual boxes. However, if you’re going to use it for self-defense, then you can go for fewer rounds, about 20. This is because you might need as many.
