Which 22 Cartridge is the Most Powerful?

Choosing the most powerful 22 caliber ammunition can be a challenging task, as there are several cartridges available that are considered to be among the best. However, the .22 Magnum and the .220 Swift are often mentioned as the most powerful options. In this article, we will explore these cartridges and other contenders to help you make an informed decision.

The .22 Magnum

The .22 Magnum, also known as the .22 Magnum Rimfire (MR), is a highly versatile ammunition that is popular among shooters and hunters. However, it is not always considered the most powerful 22 cartridge, as other options offer greater terminal ballistics and "lethality."

The .220 Swift

The .220 Swift has been a top contender in the realm of powerful 22 ammunition since the 1930s. This cartridge is known for its exceptional speed and power, making it a preferred choice for hunting small game and varmints. Some argue that newer cartridges, such as those designed to use heavier bullets, are more powerful. However, the .220 Swift's unmatched raw speed keeps it at the top of many lists.

Key Features of the .220 Swift

Velocity: With a muzzle velocity often exceeding 3,000 feet per second (fps), the .220 Swift outpaces many of its competitors. Accuracy: The .220 Swift is renowned for its accuracy, making it a top choice for precision shooting and hunting. Power: Despite its small calibre, the .220 Swift delivers a substantial amount of energy, making it effective for hunting purposes. Flexibility: It can be used effectively for both hunting and target shooting, offering versatility in its applications.

The .22 Long Rifle (LR)

The .22 Long Rifle (often abbreviated as .22LR) is perhaps the most widely used ammunition in the world. It is available in various loadings, each with its own unique characteristics and performance.

The CCI Stinger

Among the fastest loads, the CCI Stinger is notable for its high muzzle energy and vicious hollow-point design. However, the Stinger has a slightly longer chamber, which may cause issues with some firearms.

CCI Velocitor

The CCI Velocitor is a more balanced option. It uses a standard .22LR case and has a slightly heavier bullet, providing comparable performance to the Stinger. In my experience, the Ruger 10/22T loves the Velocitor, and they offer excellent accuracy and performance without the chambering issues of the Stinger.

Other .22LR Loadings

There are several other exotic .22LR loadings that may offer faster velocities, but for effective terminal ballistics, the CCI Velocitor, CCI Stinger, and CCI Green Tag are often considered the best. They also offer interchangeable accuracy and allow for easy adjustment of elevation, making them ideal for hunting and target practice.

Choosing the Right .22 Cartridge

When selecting the most powerful 22 cartridge, it is essential to consider your specific needs. For hunting small game, the .220 Swift and the .22LR loads mentioned above may be the best choices. For target shooting or varmint hunting, you may prefer a cartridge like the .22 Magnum. Always ensure that the ammunition you choose is suitable for your firearm and complies with local regulations.

Conclusion

Judging the most powerful 22 cartridge is subjective, but the .220 Swift and the .22LR loads stand out. Understanding the features and performance of each cartridge can help you make an informed decision and choose the best option for your needs.
