A Full Guide To Airsoft Ammo Types

Airsoft is a straightforward "point and shoot" sport. 

You'll need eye protection, an airsoft pistol, and a magazine of airsoft BBs to get started. To begin, let's define airsoft BBs. Airsoft BBs are similar to paintball BBs in that they are used as ammunition in airsoft weapons. 

They fire little plastic pellets or "BBs" instead of paint. These pellets are used for target practice and to safely tag other airsoft players during team matches and games involving force-on-force combat. While playing airsoft, safety is paramount, and each participant is required to wear eye protection!

Have you ever wondered about the many varieties of airsoft BBs, their manufacturing process, or which ones you should use? 

Did you know that BBs come in various shapes, sizes, and colours? If you did, fantastic; if you didn't, you've arrived at the right place! 

Choosing the correct kind of airsoft BB will significantly improve your performance on the airsoft field.

How To Choose The Right Airsoft BB?

Standard airsoft BBs are all 6mm in diameter. 

This is because most airsoft weapons, such as pistols, rifles, sniper rifles, and squad support airsoft guns, include magazines that take 6mm airsoft BBs and barrels that are 6mm in diameter.

If you're unclear about the BB size that your airsoft gun uses, seek 6mm airsoft BBs.

Most likely, your airsoft gun is a 6mm airsoft gun. If you're unsure of the airsoft BB size that your airsoft gun allows, consult your airsoft gun's owner's handbook, look for markings on the airsoft gun magazine, or check online by searching for the airsoft gun's model number and manufacturer.

However, certain airsoft BBs are available in a more significant 8mm size. These bigger airsoft BBs are most often seen in speciality airsoft guns such as revolvers and close-range weapons. 

The bigger 8mm diameter of the airsoft BB results in increased air resistance as it travels through the air. This makes it more difficult to utilise these bigger BB sizes in longer-range airsoft weapons.

Generally, you will know whether your airsoft gun fires 8mm airsoft BBs.

An airsoft BB pellet's millimetre (mm) size is an approximate measurement of its diameter. These dimensions enable them to be fired from most spring-powered airsoft guns, automatic-electric-gun (AEG)-powered airsoft weapons, and gas-powered airsoft guns.

Plastic moulding is used to create Airsoft BBs. In a nutshell, the production process of airsoft BBs consists of the following steps: material selection, sorting, melting, material injection, polishing, and packing.

Why Do You Need High-Quality BBs?

The size of the airsoft BB enables it to fit neatly into the barrels of airsoft guns. This is critical for the airsoft gun's accuracy and the airsoft BB's flight stability. 

The inside diameter of the airsoft pistol barrel is only slightly larger than the BB size. When the BB is shot, less air escapes around it, and more air forces the BB out of the barrel.

Consequently, the airsoft BB's feet-per-second (FPS) performance rate is boosted. 

Consider purchasing high-quality airsoft BBs that have been manufactured using a seamless plastic moulding method. This kind of airsoft ammunition is often created using injection moulding, with a spherical BB design, and moulded with entirely seamless airsoft BBs. 

The airsoft BBs are then twice polished to guarantee that each 6mm BB has a diameter of 5.95mm +/- 0.1mm and is precisely round.

The word "FPS" refers to the rate at which airsoft guns fire a BB. It is comparable to the rate of fire (ROF), which comprises rounds per minute (RPM) and rounds per second (RPS).

These two things refer to the number of BBs fired by an airsoft pistol every minute or second. Certain airsoft guns have very high RPMs and may fire hundreds of BBs per minute. 

For instance, some squad support machine airsoft weapons can fire up to 38 airsoft BBs every second, or 2,280 per minute! Most airsoft fields have FPS restrictions, so be careful to check with field officials before playing.

Additionally, tighter barrels or "tight bore barrels" may be added to airsoft guns to boost the FPS of airsoft BBs. For instance, many AEGs that fire 6mm BBs often have a 6.08mm barrel. 

The barrel may be modified to a 6.01mm or 6.03mm tight bore barrel for improved tolerances and performance. A tight bore barrel allows for less air to escape surrounding the airsoft BB when it is shot, boosting the BB's FPS. 

Since high-quality 6mm airsoft BBs are 5.95mm +/- 0.1mm and completely round, an improved barrel ensures that the BB fits precisely within the barrel with just roughly 0.07mm of clearance. This increases the range of your airsoft BBs!

Picking The Right BB Weight

Airsoft BBs are available in a variety of standard weights. 0.12-gram and 0.20-gram BBs are the most popular weights. 

Additionally, 0.25 gram, 0.28-gram, 0.30-gram, and up to 0.40-gram BBs are popular. The weight of the airsoft BB affects the amount of effort required to push it out of the airsoft pistol and guide its flight direction once you’ve fired.

Airsoft BBs of a lower weight, such as 0.12-gram BBs, are typically suited for close-range targets. They are primarily employed in spring-powered airsoft weapons that discharge them at a rate of around 250 feet per second. 

Internally hollow, these BBs are the most accurate at close ranges. They are not suggested for use in airsoft weapons with a higher FPS since they have a tendency to shatter, resulting in damage to the airsoft gun, and are almost entirely ineffectual and inaccurate at extended ranges.

Weights in the 0.20-gram to 0.28-gram range are considered "middle of the road" for airsoft BBs. 

These BBs have the greatest range of use since they are balanced, being light enough to be used easily in airsoft guns with lower FPS at closer ranges yet powerful enough to be used in airsoft weapons with higher FPS at extended ranges. However, their flight trajectories are not as steady as heavier BBs, making them less suitable for extreme long-range use.

Heavier airsoft BBs, such as 0.30 to 0.40 gram BBs, are optimised for maximum flight stability and range. They are most often seen in high-powered airsoft sniper rifles and AEGS. 

It takes more energy to fire these heavier BBs, but they fly more stably and accurately as a result. Airsoft BBs are available in a number of popular sizes and weights online, including 6mm and 8mm diameters and 0.20-gram, 0.25-gram, 0.28-gram, and 0.32-gram weights. 

These BB weights are compatible with most airsoft weapons and provide excellent accuracy from close to long ranges. This enables players to choose the optimal BB weight for every airsoft game.

What Happens To My BBs After I Shoot Them?

After being fired, the quality of airsoft BBs is only as good as the substance used to make them. There are several variables to consider regarding BB quality, but there are a few critical points to remember. 

There are two extremely popular kinds of BB materials accessible to airsoft players: non-biodegradable and biodegradable. Airsoft BBs that are not biodegradable are often constructed of acrylonitrile butadiene styrene (ABS). 

ABS airsoft BBs are the least expensive, do not deteriorate considerably over time, are not really ecologically friendly, and are insoluble in water. 

As a result, many outdoor airsoft grounds prohibit players from using these non-biodegradable airsoft BBs, as they will remain in the environment where they land for an extended period. 

On the other hand, ABS BBs are appropriate for interior usage where they can be readily collected and cleaned up and on private property with the owner's approval. 

Biodegradable airsoft BBs (a.k.a. "bios") are often constructed of polylactic acid or polylactide plastic (PLA). PLA plastic is made from natural and renewable resources, such as maize and specific starches. 

PLA airsoft BBs are more expensive than ABS BBs but are more ecologically friendly, soluble in water, and degrade into water and carbon dioxide in about 47 to 90 days in industrial recycling facilities or somewhat longer in the right climatic circumstances outdoors. 

Most outdoor airsoft fields require players to use biodegradable airsoft BBs of this sort.

How To Spot High-Quality BBs

High-quality airsoft BBs have a number of design factors that contribute to their performance. 

These qualities include a polished surface to eliminate moulding edges and defects, a spherical round bearing design, and a diameter of 5.95mm +/- 0.1mm to guarantee the BB fits precisely into standard airsoft gun barrels.

Now you know all you need to know about the different airsoft ammo types. Test out different types and find the ammo that works best for you, and remember to consider the requirements and restrictions of the places you are playing at.
