Introduction

When it comes to choosing the right ammunition for your firearm, there are a plethora of options available on the market. Two popular choices among gun enthusiasts are the .300 Blackout and the 2mm Kolibri. Both cartridges have their own unique attributes and characteristics that make them suitable for different purposes. In this article, we will compare and contrast the .300 Blackout and 2mm Kolibri to help you make an informed decision on which one is best for you.

Size and Caliber

The .300 Blackout is a larger caliber cartridge, measuring at .308 inches in diameter. It was designed to provide similar ballistics to the 7.62x39mm cartridge used in the AK-47, but in a smaller and more versatile package. On the other hand, the 2mm Kolibri is one of the smallest cartridges ever produced, with a diameter of only 2.7mm. Despite its tiny size, the 2mm Kolibri is still capable of firing a projectile at a high velocity.

Ballistics

When it comes to ballistics, the .300 Blackout is known for its versatility. It can be loaded with a wide range of bullet weights, making it suitable for both short-range and long-range shooting. The .300 Blackout also performs well in suppressed firearms, making it a popular choice among shooters who value stealth. On the other hand, the 2mm Kolibri has limited ballistic capabilities due to its small size. It is best suited for close-range shooting and is not recommended for hunting or self-defense purposes.

Recoil

Recoil is an important factor to consider when choosing ammunition, especially for shooters who are sensitive to recoil. The .300 Blackout has moderate recoil, similar to that of the 5.56mm NATO cartridge. This makes it comfortable to shoot for most individuals, even in rapid-fire situations. In contrast, the 2mm Kolibri has virtually no recoil due to its small size and low powder charge. This makes it an ideal choice for shooters who are recoil-sensitive or for training purposes.

Availability and Cost

Availability and cost are also important considerations when choosing ammunition. The .300 Blackout is a popular cartridge and is widely available at most gun stores and online retailers. It is also relatively affordable, with a box of 20 rounds typically costing around $20. On the other hand, the 2mm Kolibri is a rare and obscure cartridge that is difficult to find. When it is available, the cost can be quite high due to its rarity, with a single round costing several dollars.

Use Cases

Both the .300 Blackout and 2mm Kolibri have their own unique use cases. The .300 Blackout is a versatile cartridge that can be used for hunting, self-defense, and target shooting. It is particularly popular among shooters who value its subsonic capabilities for suppressed firearms. On the other hand, the 2mm Kolibri is more of a novelty cartridge that is primarily used for recreational shooting and collecting. It is not recommended for serious shooting applications due to its limited ballistic performance.

Conclusion

In conclusion, the .300 Blackout and 2mm Kolibri are two very different cartridges with their own strengths and weaknesses. The .300 Blackout is a versatile and practical choice for a wide range of shooting applications, while the 2mm Kolibri is more of a novelty cartridge with limited practical use. Ultimately, the best choice between the two will depend on your specific needs and preferences as a shooter. We hope this comparison has helped you make an informed decision on which cartridge is right for you.
