Understanding Ammunition Terminology

When it comes to choosing the right ammunition for your firearm, understanding certain industry terminology is essential. In this section, we’ll define some of the key terms you should be familiar with, and explain how they relate to shooting performance.


Caliber is one of the most important terms to understand when selecting ammunition for your firearm. It refers to the diameter of the bullet’s case, measured in inches or millimeters. While larger calibers are more powerful, they also produce increased recoil, making them better suited for target shooting rather than self-defense.

Bullet Weight

The weight of a bullet, typically provided in grains, is another important factor. Generally, heavier bullets are more precise but may have decreased velocities, whereas lighter bullets offer greater speed but could be less accurate at long distances.


The velocity of a bullet is the speed at which it travels, measured in feet per second. This affects the bullet’s ability to penetrate its target, so slow-moving bullets may not travel far enough to reach their intended destination. Higher velocities will result in greater accuracy and penetration but also more recoil.


Ballistics refer to the science of studying how projectiles move, interact, and behave in flight. This can be used to understand the accuracy and performance of ammunition, as well as the factors that can affect it such as recoil and muzzle rise.

By familiarizing yourself with the terminology of firearms and ammunition, you'll be better equipped to choose the right type for your needs. However, always consult an expert before making any purchases or using any ammunition.

Common Types of Firearms and Their Ammunition Types

When purchasing ammunition, it is important to know what type of firearm you are using, as different firearms require different types of ammunition. In this section, we will discuss the various types of firearms and their respective ammunition types.


Rifles are long guns that are typically fired from the shoulder. They tend to be more accurate than handguns due to their longer barrels and greater stability when firing. Common rifle calibers include .22LR, .223, .308, and .30-06. It is important to use the correct ammunition for your rifle to ensure accuracy and safety.


Shotguns are also long guns but differ from rifles in that they fire multiple small pellets instead of a single bullet. Shotguns are often used for hunting or in home defense situations. Common shotgun shells include 12 gauge, 20 gauge, and .410 bore. It is important to use the correct size of shell to ensure optimal performance and accuracy.


Handguns are small firearms designed to be held and fired with one hand. They vary in size, shape, and caliber but usually have a short barrel and are easy to carry. Popular handgun calibers include 9mm, .40 S&W, and .45 ACP. Be sure to purchase the correct type of ammunition for your handgun to ensure safety and accuracy.

Airguns/BB Guns

Airguns and BB guns are lower-powered firearms that use compressed air or CO2 to propel projectiles. They are often used for recreation or to practice marksmanship without using live ammunition. BB guns usually use .177 caliber BBs and airguns normally use .177 or .22 pellets. It is important to use the correct type of pellets to ensure accuracy and safety.


It is essential to know which type of firearm you have and what type of ammunition it requires. Not all firearms use the same type of ammunition and it is important to select the appropriate ammunition for your firearm to ensure safety and accuracy. Be sure to purchase the correct type of ammunition for your firearm to ensure optimal performance and safety.

Caliber and Bullet Weight: Explained

When it comes to choosing the right ammunition for your firearm, caliber and bullet weight are two of the most important factors to consider. So what do these terms mean, and how do they affect shooting accuracy, performance, and safety? In this section, we’ll provide a basic overview of both.

Caliber refers to the diameter of the bullet. Generally, the larger the caliber, the more powerful the gun and the greater the recoil. Common rifle calibers include .22, .30-06, and .50 BMG, while common pistol calibers include .380ACP and 9mm. Smaller calibers are generally used for target shooting and hunting small game, while larger calibers are used for hunting large game.

Bullet weight is simply the weight of the bullet in grains (one grain is equal to 1/7000 of a pound). Generally, lighter bullets will be faster and have less recoil than heavier bullets, while heavier bullets will be slower but have more knockdown power. Bullet weight affects both accuracy and stopping power, so it’s important to choose the right one for the job.

When selecting a caliber and bullet weight for your firearm, there are several things to take into consideration. Your firearm’s purpose should determine the type of ammunition you choose. For example, if you’re target shooting, then a light, low-recoil round would be the best option. If you’re hunting, then a larger caliber and heavier bullet may be the better choice for maximum knockdown power. Failing to choose the right ammunition could negatively impact your shooting accuracy, performance, and even safety.

By understanding the differences between calibers and bullet weights, as well as considering the intended use of your firearm, you can make an informed decision when selecting the right ammunition for your firearm. It’s worth taking the time to become familiar with ammunition terminology and types to ensure that you make the best choice possible.

Selecting the Right Ammunition for Your Firearm

When it comes to shooting, choosing the right ammunition can make a big difference in performance and accuracy, as well as safety. Here’s what you need to know about selecting the appropriate ammunition for your firearm based on its intended use.

Know Your Caliber

First, you will need to determine the caliber of your firearm. This is the diameter of the inside of the rifle or pistol barrel, which is determined by the size of the bullet and specified by the gun manufacturer. The caliber will come with a series of numbers such as .38 Special, .45ACP, and .223Rem.

Match the Bullet Weight

Once you know the caliber, you must match the appropriate bullet weight to your firearm. Generally speaking, heavier bullets work best in larger calibers, while lighter bullets work better in smaller calibers. So, when choosing the right ammunition for your firearm, take into account the bullet weight suitable for your firearm’s diameter.

Choose the Right Velocity

In addition to matching the right bullet weight to your caliber, you must also consider the bullet's velocity. This is determined by the power of the propellant used in the ammunition. High velocity ammunition will generate stronger recoil, while low velocity ammunition will generate a softer recoil. You will want to choose the velocity that fits the needs of your shooting activity.

Select the Right Ballistic Performance

Finally, you should also take into account the ballistic performance of the ammunition. This includes the trajectory, terminal performance, and accuracy of the round. Traditional ammunition will offer basic performance, while more sophisticated designs can provide enhanced performance. Consider the type of shooting you will be doing and select the best ammunition for the job.


When it comes to ammunition selection, it is important to match the caliber, bullet weight, and velocity to your firearm, as well as the ballistics performance to your intended use. With the right ammunition, you can ensure optimal performance, accuracy and safety.

Choosing Self Defense Ammunition

It is important for gun owners to understand the different types of self-defense ammunition and how to choose the proper type for specific situations. The type of self-defense ammunition you select can make a crucial difference in a dangerous situation.

Types of Self Defense Ammunition

The three most common types of self defense ammunition are hollow point, frangible, and full metal jacket (FMJ) bullets. Here is a brief description of each:

  • Hollow Point: Hollow point ammunition has a hollow area at the tip of the bullet, which causes it to expand upon impact. This expansion increases the diameter of the wound channel and makes a more effective choice for self defense.
  • Frangible: Frangible bullets are designed to break apart quickly upon impact. This prevents a projectile from penetrating through a target and causing collateral damage. It is also designed to reduce the risk of ricochet.
  • Full Metal Jacket: FMJ bullets have a soft metal jacket that completely encases the bullet. It does not expand on impact and is intended to penetrate deeply into a target. FMJ ammunition is not generally recommended for self-defense since it can easily penetrate through walls.

Choosing the Right Ammunition for Self Defense

When selecting the best type of self-defense ammunition for your situation, consider two primary factors: the design of your firearm and the desired shooting results. For example, if you have a gun with a short barrel, you should choose a round with a low velocity to help reduce muzzle flash.

In terms of shooting results, hollow-point ammunition is usually the preferred choice for self-defense because of its ability to create a larger wound channel. However, some states have laws that restrict the use of hollow points, so be sure to check your local regulations before making a purchase.

You should also be aware of any potential restrictions on ammunition size. For example, many states ban the sale of rifle ammunition with a caliber of .50 or higher. It’s also important to become familiar with your target’s material composition and range distances to ensure a safe and consistent shooting result.


Choosing the right self defense ammunition requires you to carefully assess your situation and firearm. Different types of self defense ammunition have different performance characteristics, and it’s important to understand these differences when selecting the right type for a given application. You should also be sure to check local regulations regarding ammunition size and use.
