CZ USA has taken their 457 and added improvements that have been requested and a few more to complete the upgrade. The CZ USA 457 Varmint AT-ONE has the two position push to fire safety and a Boyd's Adjustable stock for improved accuracy at varmints or targets. Other improvements are a change in bolt rotation to 60 degrees to allow larger scopes to be installed and changes in the design of the receiver and its length to reduce its weight and footprint. Topped of with an adjustable trigger you get the look and feel of a full sized bench rifle that you can feed inexpensive ammo to punch holes in your target. No matter if it is paper targets or varmints in your back 40 handle them with easy from CZ USA.

Caliber Dictionary
The Below Information Has Been Provided From Our Gun Caliber Dictionary And Is Meant For Informational Purposes Only. It Is Not Intended to Describe The Unique Specifications For This Ammunition.
Introduced by Hornady in 2002, the 17 HMR has become extremely popular and is the standard alternative to 22 rimfires for small game and small varmints. Most manufacturers who produce rimfire rifles chamber to it, and all major ammunition manufactures load ammo. The 17 HMR was created by necking down the 22 WMR cartridge, resulting in a lighter but much faster load. Most common are a 17-grain bullet at up to 2550 feet per second; and a 20-grain load at 2375. No 17-caliber bullet bucks wind particularly well, but the 20-grain bullet, though slower, holds up a bit better and tends to offer better penetration. Perhaps the greatest attribute of the 17 HMR is accuracy that is consistently good and often exceptional, effective to as far as 150 yards under calm conditions. As a hunting cartridge it should be limited to animals smaller than coyotes. — Craig Boddington
