Below we have a comparison between the .68 caliber and the .50 caliber which is another common size.

The .68 Caliber Paintball

Most players especially the ones that are more experienced prefer the .68 caliber paintball because it’s a lot more versatile and can be used in most games. We really like the fact that these paintballs can also be used in both indoor and outdoor of different layouts and sizes.

A huge benefit that comes with the .68 caliber paintball is that it also has a great velocity and an excellent splat effect upon hitting the opponent.

The only drawback that comes with the .68 caliber paintball is its weight. It is considered to be a lot heavier compared to the .50 caliber along with the paintball gun that holds them.

For beginners and kids just starting out in the sport this extra weight might become since they don’t have the experience to handle them. Another thing with the .68 caliber is that they tends to hurt more when they hit an opponent. With that said, experience players may have enough shooting practice to avoid all problems from taking place.

The .50 Caliber Paintball

The .50 caliber paintball also refer as the “low impact” paintball, has recently become extremely popular on the market. This paintball is relatively smaller in size which means that it hurt less when hits opponents, making it the perfect fit for beginners and kids between the ages of 10 to 12. It’s also a great choice for indoor fields recreational games.

The only disadvantages that comes with these paintballs is the fact that they are only half an inch in diameter, meaning that you will experience reduced velocity. It will also travel a lesser distance compared to the .68 caliber paintball. Another thing is that the .50 caliber won’t break upon hitting the target. However, it can still be loaded easily into the marker and you don’t have to stop regularly during a match to reload.

Apart from the .68 and .50 caliber paintball, there are other types of paintball that you should consider when choosing the correct paintball for your gun. These include:

Recreation Paintballs

These paintballs are very unique they tend to have s stronger and thicker shell and can ge used on any paintball gun that is of the right size. They are also very affordable because of their inconsistent shape, so even if you’re on a tight budget you should still be able to afford these paintballs.

Tournament-Grade Paintballs

These paintballs on the other hand tends to have a thinner shell, which means they can travel more efficiently and consistently. They are often used with higher end paintball guns and in professional tournaments.

Now that you have an understanding about paintball sizes, it is also important to choose the perfect barrel for it:

What is the Most Common Paintball Barrel Bore Size?

If you’re unfamiliar, the barrel bore size is the inside diameter of the paintball marker barrel. What a lot of people don’t know is that the size of the barrel bore and paintball are usually not the same.

There are two common paintball bore sizes: the .685 caliber and .689 caliber. Between these two, the .685 is considered to be the most popular bore size on the market at the moment.

Choosing the right bore size is very important as it plays a huge role in terms of improving the accuracy. In order to select the correct bore size, all you have to do is place a paintball inside the barrel; if it rolls out easily, it is too small and if its get stuck, it’s too big.

This is why we believe the best idea would be to invest only in the .685 caliber or the .689 caliber. Buying both isn’t necessary, as your paintballs will only work with one of the two sizes.

  • If you already have a paintball gun, what you can do is use the caliber of the marker to help you choose a paintball size.
  • We don’t recommend picking up paintballs from the ground and reused them into the loader. The dirt on on these paintballs can easily clog the barrel and affect your gun’s ability to fire.
  • If you’re planning on purchasing a paintball marker in the near future, you should opt for one that meets your budget criteria and your level of experience.
  • You should take the time out to test how hard the paintballs are before purchasing. Often paintballs turn out really soft when exposed to moisture.
