This video provides an expert-level assessment of the CZ 457 rifle chambered in .22 Winchester Magnum Rimfire (.22 WMR). The instructor, demonstrating high authority and decades of experience, meticulously tests various ammunition types for accuracy and velocity. Key takeaways include the .22 WMR's effective range advantage over .22 LR due to maintaining supersonic speeds and its suitability for varmint and medium-sized game hunting in regions like the Northeast US.

Quick Summary

The CZ 457 in .22 WMR offers an extended effective range up to 150 yards due to its ability to maintain supersonic velocity longer than .22 LR, which becomes transonic around 45-50 yards. Tested ammunition like CCI VNT and Maxi-Mag showed excellent accuracy at 60 yards, making it suitable for varmint hunting.

Frequently Asked Questions

What is the effective range of the .22 WMR cartridge?

The .22 WMR cartridge can maintain supersonic velocity significantly longer than .22 LR, extending its effective range for accuracy and terminal ballistics to approximately 150 yards, whereas .22 LR typically becomes transonic around 45-50 yards.

How does the CZ 457 perform with .22 WMR ammunition?

The CZ 457 chambered in .22 WMR demonstrated exceptional accuracy and smooth operation during testing. Specific loads like CCI VNT and CCI Maxi-Mag showed impressive grouping at 60 yards.

Is .22 WMR suitable for hunting coyotes?

For smaller Western coyotes, .22 WMR can be adequate. However, for larger 40-50lb coyote strains common in regions like the Northeast US, a more powerful .22 centerfire rifle is generally recommended.

What is the significance of transonic ballistics for rimfire cartridges?

Transonic ballistics refers to the speed range near the speed of sound. When a projectile enters this range, aerodynamic instability can significantly disrupt accuracy. .22 WMR's advantage is staying supersonic longer than .22 LR.
