Buy 223 Remington Ammo Online

The .223 Remington is one of America’s most popular rifle cartridges — the
civilian standard behind the AR-15 and a favorite for range training, varmint
and predator hunting, and target shooting. Affordable, accurate, and
low-recoiling, .223 Rem is the round countless shooters buy by the case. At
Trigger Ammo Store, we carry a deep selection of .223 Remington ammunition from
budget-friendly bulk range loads to precision match and explosive varmint
rounds, so you can keep your rifle fed for any purpose.

What Is the 223 Remington?

Introduced commercially by Remington in 1964, the .223 Remington fires
lightweight, high-velocity .224-caliber bullets and became the parent of the
later 5.56x45mm NATO military cartridge. Its flat trajectory, mild recoil, and
low cost made it the dominant civilian sporting cartridge it is today — equally
at home punching paper, ringing steel, dropping coyotes, or training new
shooters. In the AR-15 platform, it delivers fast, accurate, easy-shooting
performance round after round.

223 Remington vs 5.56 NATO — READ THIS BEFORE YOU BUY

This is the single most important thing to understand when buying .223 ammo.
The .223 Remington and 5.56x45mm NATO are nearly identical in external
dimensions, but they are NOT the same: 5.56 NATO is loaded to higher pressure
and uses a different chamber throat (leade). The safe-use rules are:

• Rifle chambered in .223 Remington only: Fire ONLY .223
  Remington. Firing higher-pressure 5.56 NATO in a .223-only chamber can produce
  excessive pressure and is not recommended.
• Rifle chambered in 5.56 NATO: Can safely fire BOTH .223
  Remington and 5.56 NATO.
• Rifle chambered in .223 Wylde: A hybrid chamber that
  safely shoots both .223 Remington and 5.56 NATO with excellent accuracy.

Good news for .223 buyers: .223 Remington is the “safe in everything” choice —
it can be fired safely in .223, 5.56, and .223 Wylde chambers alike. Always check
your barrel’s marked chambering, and when in doubt, consult your rifle’s maker or
a qualified gunsmith. For authoritative specs, see SAAMI.

What Is 223 Remington Good For?

• Range & training: Affordable bulk ammo makes .223 the
  default choice for practice and high-round-count range days.
• Varmint & predator hunting: Fast, flat-shooting loads
  excel on coyotes, prairie dogs, groundhogs, and other varmints.
• Target & competition: Heavier match loads (69–77
  grain) deliver excellent accuracy for precision and 3-gun shooting.
• Home defense: Proper defensive loads offer effective,
  low-recoil performance from an AR-15.

Common 223 Loads & Bullet Weights

• 55 grain FMJ: The classic, affordable range and training
  load for high-volume shooting.
• Varmint (40–55 grain polymer-tip): Fast, explosive bullets
  (V-MAX-style) built for dramatic varmint performance.
• 62 grain: A heavier general-purpose weight popular for
  defense and all-around use.
• Match (69–77 grain): High-BC bullets for long-range
  accuracy and competition.

Frequently Asked Questions

Can I shoot .223 in a 5.56 rifle?

Yes. .223 Remington can be safely fired in rifles chambered for .223
Remington, 5.56 NATO, and .223 Wylde. It’s the “safe in everything” choice. The
reverse is not true — don’t fire 5.56 NATO in a .223-only chamber.

What’s the best .223 ammo for varmint hunting?

Fast, polymer-tip bullets in the 40–55 grain range (like V-MAX-style loads)
are popular for explosive varmint performance on coyotes and prairie dogs.
