The products and packages you see on this page are .224" bullets only - just the projectile. For loaded ammo ready to fire in your rifle, please see our 223 ammo page.

If a cartridge is going to become very popular, it could receive few greater blessings than adoption by the United States Armed Forces. Case in point: The 223 Rem, which was adopted alongside the M16 rifle in 1964. The cartridge would later evolve into the 5.56x45 which shares identical physical dimensions as well as the same .224 diameter bullet.

You can break down .223 bullets for reloading into four major categories. Very light bullets in the 40 grain range permit extra fast muzzle velocities, ideal for when a flat trajectory followed by a shallow wound channel are desired for varmint hunting. 55 grain bullets are essentially the standard weight and best for when you want performance like the U.S. Army’s M193. 62 grain bullets may include a seven grain steel penetrator tip, but even without them they perform ballistically like the U.S. Army’s M855. Finally come the heavyweights at 70, 77 and 90 grains. These bullets possess extra mass that gives them greater momentum downrange, key for long distance shooting where wind drift enters heavily into the equation.

Heavier bullets demand faster barrel twists to best benefit accuracy. A 1:12 twist will adequately stabilize 55 grain .223 bullets, but a twist as fast as 1:7 is ideal for bullets 70 grains and heavier.

The 223 Rem and its higher pressure variant the 5.56x45 are the kings of the American rifle range. FMJ and FMJBT bullets are optimal for affordable high volume shooting, and deliver the requisite accuracy for effective training and satisfying plinking. V-MAX and other polymer tip bullets deliver the expanding terminal performance that hunting and personal protection call for. And when you’re trying to hit the most distant targets, the superior ballistic coefficient of the HPBT will serve you particularly well.

    Perfect match for my 1 in 7 twist.

    Every barrel/chamber combination likes something and this would be it! The NATO spec chamber is tough to get good accuracy but this long Sierra Match King works well with Reloder 15 and BL-C (2).

    best of the 77 gn

    i've tried a about 4 different brands of 77gn .223 bullets. The Sierra MK work best for me. They are very consistant.

    Great long range for Armalite M15 Target Rifle

    The Sierra MatchKing reputation convinced me to order these for long range target shooting. Thank you Wideners for fast shipping, great customer service, and providing quality products to all of us.

It has an outstanding reputation for accuracy, and delivers some of the best terminal performance in the ammo industry.
