Buy 220 Swift Ammo Online

The .220 Swift is the legendary speed king of varmint cartridges — for
decades it held the title of the fastest commercial cartridge in the world, and
it’s still one of the flattest-shooting, hardest-hitting varmint rounds you can
buy. Built for blistering velocity and dramatic terminal performance on small
game, the Swift is a favorite of dedicated long-range varminters and predator
hunters. At Trigger Ammo Store, we carry .220 Swift ammunition to feed this
fast-shooting classic.

What Is the 220 Swift?

Introduced by Winchester in 1935, the .220 Swift was the first factory
cartridge to break the 4,000 feet-per-second barrier, instantly cementing its
reputation as the ultimate high-velocity varmint round. It fires light
.224-caliber bullets at extreme speed, producing an exceptionally flat trajectory
and explosive results on varmints. Nearly 90 years later it remains a beloved
specialist cartridge — a flat-shooting, long-reaching varmint round with a
genuine place in firearms history.

What Is 220 Swift Good For?

• Long-range varmint hunting: Its blistering velocity and
  flat trajectory make it superb on prairie dogs, ground squirrels, and other
  small varmints at extended range.
• Predator hunting: Fast, explosive bullets are deadly on
  coyotes and other predators.
• High-velocity flat shooting: For shooters who want
  maximum speed and the flattest possible trajectory in a varmint rifle.

Types of 220 Swift Ammo We Carry

• Polymer-Tip Varmint: Fast, explosive bullets (V-MAX and
  Ballistic Tip styles) built for dramatic terminal performance on varmints.
• Hollow Point Varmint: Classic rapidly-expanding bullets
  for small game and predators.
• Soft Point: Traditional expanding loads where a bit more
  bullet integrity is wanted.

Common 220 Swift Bullet Weights

The .220 Swift is loaded with light, fast .224-caliber bullets to maximize
velocity. The most common weights run from about 40 to 55 grain,
with 40–50 grain polymer-tip and hollow-point bullets being the
varmint favorites — light enough to reach the Swift’s signature blazing speeds
and built to expand explosively on small targets. Heavier 55-grain loads offer a
bit more wind resistance for longer shots.

Top 220 Swift Ammo Brands

We stock .220 Swift ammunition from the manufacturers varmint hunters trust,
including Hornady, Federal, Winchester, and Remington. From explosive polymer-tip
varmint loads to classic hollow points, you’ll find quality ammo for a specialty
caliber that isn’t always easy to find fully stocked elsewhere.

A Note on Barrel Life & Care

The .220 Swift’s extreme velocity is its greatest strength — and the reason it
has a reputation for burning out barrels faster than slower cartridges,
especially with heavy, sustained rapid fire. Many Swift shooters simply let the
barrel cool between strings during high-volume varmint sessions to extend its
life. It’s a small trade-off for the cartridge’s unmatched speed, and modern
barrels and quality ammo make it less of a concern than in decades past.

Availability & Buying Tips

The .220 Swift is a classic specialty caliber with a smaller, dedicated
following, so factory ammo isn’t stocked as deeply as mainstream varmint rounds
and selection can be limited. It pays to buy when you see your preferred load in
stock — grab enough for your varmint season, and set a stock alert so you’re
never caught short before a prairie-dog trip.

Frequently Asked Questions

What is the 220 Swift best for?

The .220 Swift is a dedicated long-range varmint and predator cartridge,
prized for its blistering velocity and flat trajectory on prairie dogs,
coyotes, and similar small game.

Does the 220 Swift really burn out barrels?

Its extreme velocity does increase barrel wear compared to slower cartridges,
especially with sustained rapid fire. Letting the barrel cool between strings
helps. Modern barrels handle it well, and for most varmint hunters it’s a minor
trade-off for the speed.
