The bullets available for the .22-250 span a wide range of weights, from lighter bullets optimized for extreme speed and explosive expansion in varmint hunting, to heavier bullets that offer greater sectional density and better retained energy at longer ranges. The ability to accommodate this wide range of bullet weights adds to the versatility of the cartridge.
Advantages of the .22-250
The advantages of the .22-250 Remington are numerous. Its high velocity and flat trajectory make it a natural choice for varmint hunting, allowing hunters to accurately engage targets at extended ranges. A wide selection of ammunition and components is readily available, from factory loads to reloading supplies, making it a relatively easy cartridge to work with. The inherent accuracy of the .22-250, when coupled with a quality rifle and appropriate optics, is legendary. The cartridge is often credited with having excellent accuracy at ranges from close range to three hundred or even four hundred yards.
Disadvantages of the .22-250
However, the .22-250 is not without its drawbacks. High velocities come at a price, and the cartridge can exhibit a relatively short barrel life, meaning that the rifling in the barrel will wear out faster compared to some other cartridges. The .22-250 can also be sensitive to wind drift, which can affect long-range accuracy.
The Enhanced Version: The .22-250 Ackley Improved
The Ackley Improvement Process
The .22-250 Ackley Improved is a direct descendant of the original .22-250 Remington, born out of a desire to extract even more performance from the platform. The “Ackley Improved” designation is a testament to the ingenuity of P.O. Ackley, a renowned firearms innovator who developed a series of “improved” cartridge designs that increased both velocity and efficiency. The key to the Ackley Improved design lies in its modified case geometry, engineered to maximize performance.
The transformation of a standard .22-250 into an Ackley Improved version involves a process called “fire-forming,” where the standard case is fired in a custom chamber. The alterations usually include a steeper shoulder angle and a slight increase in body taper. These modifications, subtle as they may appear, lead to significant performance gains. This often requires the shooter to reload rounds.
Cartridge Specifications (Compared to the Standard .22-250)
The .22-250 Ackley Improved boasts several advantages in its specifications. By modifying the shoulder angle of the .22-250 cartridge, the Ackley Improved cartridge reduces case stretch. The increased body taper, the most noticeable change in design, and increased internal volume of the case are critical to boosting performance. These case modifications contribute to increased powder capacity, where the larger powder capacity allows for increased velocities.
Performance Characteristics
The performance characteristics of the .22-250 Ackley Improved are where its true advantages shine. The increased powder capacity enables higher muzzle velocities, often by a hundred feet per second or more compared to the standard .22-250. This translates to an even flatter trajectory, extending the effective range and reducing the need for holdover at longer distances.
The .22-250 Ackley Improved also allows for a greater number of bullet weights, and the bullets themselves are more versatile, leading to its advantages. The increase in speed from these modifications allow a greater range in their utility and purpose.
Advantages of the .22-250 Ackley Improved
The .22-250 Ackley Improved offers several compelling advantages to the shooter. The enhanced velocity translates into a flatter trajectory and improved downrange performance. It often features a longer effective range and reduced wind drift.
Disadvantages of the .22-250 Ackley Improved
The .22-250 Ackley Improved also has several disadvantages that need to be considered. The cartridge, in contrast to its base, often requires a custom chambering to get the most out of the cartridge. The improved case design can put more wear and tear on the barrel when compared to its base.
The availability of ammunition and components can be a factor. Because it is not a standardized cartridge, ammunition can be challenging to find and may require custom-loaded rounds.
Head-to-Head Comparison: .22-250 vs. .22-250 Ackley Improved
Ballistics Comparison
To provide a comprehensive understanding, a side-by-side comparison of the ballistic capabilities is essential. While data can vary depending on the specific load, here’s a generalized overview:
The .22-250 Remington can typically achieve muzzle velocities between three thousand five hundred and three thousand eight hundred feet per second, depending on the bullet weight and powder used. This results in a drop of approximately inches at three hundred yards when zeroed at one hundred yards.
The .22-250 Ackley Improved, with its increased powder capacity, often achieves muzzle velocities of over three thousand eight hundred feet per second, and sometimes exceeds four thousand feet per second. This increased speed translates to even less drop over the same distance.
