What is 7.65 caliber?

When I started learning shooting in the late 90’s, everything was fascinating for me. The firearm world is different from this regular world. This world has its language, which is not understandable by everyone. You have to be an expert in firearm science to master this lingo. I remember many of my fellow learners quit the training classes because of the complex firearm dictionary.

Clark and I were the only ones at that time who were interested in learning every single term. Clark had good access to the internet in that era. He searched for new terms, and then we usually discussed those terms every time before the class. In that way, we grasp the way to survive in the gun world.

Now the internet is full of useful information. By reading several blogs and getting training from an expert will make you professional in a short time.

The caliber is a crucial term to understand. As you have asked about the specific caliber you can check out YouTube. Watch this video:

What is 7.65 caliber?

Caliber is referred to the diameter of the bore in a firearm. This term can easily be expressed in millimeters or inches. Some people also refer to bullet diameter as caliber. 

 The term bullet is itself misunderstood by many people. Only a few of them know that the bullet is the fired projectile from the gun. No, it is not firearm ammunition, so do not mislead.

Measurements for caliber

The unit of caliber is defined by its manufacturing origin. So, you can expect a different unit of caliber if you are in the USA. You can see the imperial measurements like .32 caliber or metric measurement like 7.6 mm.

Fun fact about caliber measurement

If you are a Math Nazi, then these caliber measurements are not for you. The more you delve into units, the more you lose your mind. For example, .38,.38 Special, and .357 magnum all bear 38 calibers. It is because the bullet diameter is 357,000/inch. Isn’t it a bit confusing? Well, I am sure it is.
