This video compares the 5.7x28mm and .22 Magnum cartridges, highlighting their differences in construction and performance. While the .22 Magnum is a rimfire round with lighter bullets, the 5.7x28mm is a centerfire, bottlenecked cartridge often using heavier bullets. Testing showed the 5.7x28mm achieved greater penetration in water jugs despite similar perceived recoil and muzzle flash.

Quick Summary

The 5.7x28mm is a centerfire, bottlenecked cartridge often using heavier bullets, while the .22 Magnum is a rimfire round. Testing showed the 5.7x28mm achieved greater penetration in water jugs and had similar perceived recoil to the .22 Magnum, despite different reported velocities and energies.

Frequently Asked Questions

What is the main difference between 5.7x28mm and .22 Magnum cartridges?

The primary distinction is that the 5.7x28mm is a centerfire cartridge, while the .22 Magnum is a rimfire cartridge. This affects their internal design and how they are ignited. The 5.7x28mm also typically uses heavier bullets and has a bottlenecked case.

How does the recoil of the 5.7x28mm compare to the .22 Magnum?

Interestingly, during testing with the Ruger 5-7 and Kel-Tec PMR-30, the 5.7x28mm was perceived to have similar or even less recoil than the .22 Magnum, despite potentially higher energy output.

Which cartridge offers better penetration, 5.7x28mm or .22 Magnum?

In a water jug penetration test, the 5.7x28mm round demonstrated superior penetration compared to the .22 Magnum. This suggests it carries more energy or maintains bullet integrity better upon impact.

What are the typical bullet weights and velocities for these cartridges?

The tested .22 Magnum load was a 30-grain V-Max at approximately 2,200 fps with 320 ft-lbs of energy. The 5.7x28mm used a 40-grain V-Max at about 2,000 fps with 250 ft-lbs of energy.
