From its robust construction to its customizable features, the CZ 457 AT-ONE is designed to meet the needs of both target shooters and hunters alike. At the heart of the CZ 457 AT-ONE lies its precision-engineered action. Built upon CZ’s renowned 457 platform, this rifle boasts a smooth bolt operation, ensuring reliable cycling and consistent shot-to-shot accuracy. Whether you’re plinking at the range or taking aim at small game, the CZ 457 AT-ONE’s dependable action provides the foundation for precise shooting.
One of the most notable features of the CZ 457 AT-ONE is its fully adjustable stock system. The Boyd’s AT-ONE stock, as the name suggests, offers shooters the ability to customize various aspects of the rifle’s ergonomics to suit their preferences and shooting style. This includes adjustments for length of pull, comb height, and even the angle of the grip. By tailoring the stock to fit their body and shooting position, shooters can achieve optimal comfort and control, resulting in improved accuracy and reduced fatigue during extended shooting sessions.
The stock of the CZ 457 AT-ONE is crafted from high-quality laminated wood that looks great. It also adds a little extra weight that helps increase stability while shooting. The rifle’s robust stock can withstand the rigors of hunting or competition use while maintaining its performance and appearance.
In addition to its adjustable stock, the CZ 457 AT-ONE features a heavy-profile barrel that delivers exceptional accuracy. Available in various calibers including .22 LR, .17 HMR, and .22 WMR, this rifle is capable of delivering tight groupings at both short and long distances. Whether you’re honing your marksmanship skills or pursuing small game, the CZ 457 AT-ONE’s precision-engineered barrel ensures consistent performance and reliable shot placement.
Another benefit of the CZ 457 AT-ONE is its versatility. The rifle comes equipped with a 16.5-inch threaded barrel, allowing for the attachment of muzzle devices such as suppressors or compensators. This versatility enables shooters to tailor the rifle to their specific needs and preferences, whether they’re seeking a short small game hunting rig, a competition setup, or a quieter plinking experience.
The CZ 457 AT-ONE also features an adjustable trigger system, allowing shooters to fine-tune the trigger pull to their liking. Whether you prefer a light and crisp pull for precision shooting or a slightly heavier pull for added safety, the rifle’s adjustable trigger ensures a consistent and predictable break shot after shot.
Range Time
I took the CZ 457 to the range on a clear 60-degree morning with virtually no wind. For ammo testing, I fired three different factory loads at 50 yards from a shooting rest and a rear pinch bag. From this, I calculated the average of five 5-shot groups for each load.
SK Match 40gr Solid Point
First, I tested the SK Match 40-grain soft point. It has shot well out of several other Savage rifles I’ve tested. The ammo produced an average group size of 0.538, with the smallest group measuring in at .395.
SK Long Range Match 40gr Solid Point
Next up was SK Long Range Match 40-grain solid point ammo. SK designed this round to stretch the 22LR out to 100 yards and beyond. This round produced the best average group size at .535, and produced the smallest single group at .375. To me, this is really impressive for match ammo from an affordable Base Class rifle.
Lapua CenterX 40gr Solid Point
Finally, I tested the new Lapua CenterX 40-grain solid point ammo. It produced an average group size at .630, and the best group measured .531.
Bonus Stage – 100 Yard Testing
I also tested the SK Long Range Match 40-grain at 100 yards, because that distance is often where you can start seeing more variation in velocity and accuracy. The ammo continued to perform producing an average group size at .914, and the best group measured .813. Not wanting the fun to end there, I had a ball stretching the long-range ammo out to 300 yards on steel targets.
Wrap Up
In summary, the CZ 457 AT-ONE rimfire rifle offers a winning combination of precision, adaptability, and versatility. With its adjustable stock, heavy-profile barrel, and reliable action, this rifle is well-suited for a variety of shooting applications, from target shooting to hunting. Whether you’re a seasoned marksman or a novice shooter, the CZ 457 AT-ONE delivers the performance and features you need to excel in the field or on the range.
