.220 Swift Ammo: In Depth

The .220 Swift is a high-velocity centerfire rifle cartridge developed by Winchester in 1935. It was the first factory loaded rifle cartridge to break the 4,000 ft/s (1,200 m/s) barrier. Known for its flat trajectory and exceptional accuracy, the .220 Swift has been a favorite among varmint hunters and long-range target shooters for decades. Its high velocity and relatively light bullet weight make it particularly effective for small game hunting and pest control.

History and Development

The .220 Swift was introduced by Winchester in 1935 as a new high-velocity cartridge. It was based on the .250-3000 Savage case, necked down to .224 caliber. The cartridge was designed to achieve unprecedented velocities, pushing a 48-grain bullet to speeds over 4,000 ft/s.

Initially, the .220 Swift faced challenges due to the limitations of rifle barrel technology at the time. The extreme velocities caused rapid barrel wear, leading to concerns about the cartridge's practicality. However, advancements in metallurgy and barrel manufacturing techniques have largely mitigated these issues.

Throughout its history, the .220 Swift has maintained a dedicated following among varmint hunters and long-range shooters. Its flat trajectory and high velocity make it exceptionally effective for shooting small targets at extended ranges. The cartridge has also found use in benchrest shooting competitions, where its inherent accuracy potential can be fully realized.

Despite facing competition from newer cartridges like the .22-250 Remington, the .220 Swift has retained its place in the shooting world. Modern loadings have expanded its versatility, with heavier bullets improving its performance on larger varmints and even some small predators.

Ballistic Performance

The .220 Swift's claim to fame is its exceptional velocity. With standard 40-55 grain bullets, it achieves muzzle velocities between 3,800 and 4,100 ft/s. This high velocity translates to a very flat trajectory, making range estimation less critical for accurate shooting at moderate distances.

The cartridge's high velocity also results in explosive expansion on small targets, making it highly effective for varmint control. However, this same characteristic can lead to excessive meat damage on larger game, limiting its use primarily to small game and varmint hunting.

Modern loadings have expanded the .220 Swift's versatility. Heavier bullets in the 60-75 grain range, while not achieving the same extreme velocities, offer better ballistic coefficients and improved long-range performance. These heavier loads have made the .220 Swift more suitable for larger varmints and even small predators at extended ranges.
