These Winchester 5.56x45 Match Grade rounds have been a long time favorite of shooters in the competition world, military world, and law enforcement. Many shooters have used and prefer to use the 5.56x45 or 5.56 NATO round in their rifles and these loads have become a staple in the testing of barrel accuracy. Using a Sierra Match King 77 grain Boat Tail Hollow Point 5.56 NATO bullet, these rounds have the ability to deliver higher terminal effect than the usual 62-grain 556 NATO bullet.

The Sierra Match King bullet also features a thick-walled copper jacket with a deep hollow point cavity and a high ballistic coefficient. These bullets are loaded into new, reloadable, non-corrosive Boxer primed, heavy duty brass cases. They have a muzzle velocity of 2750 feet per second, and a muzzle energy of 1293 foot pounds. These rounds are the ideal choice for any long-range shooting competition and any other application where accuracy is absolutely imperative. These loads come in 20 round boxes and are easy to transport to the range or anywhere you want to take them. Use these rounds to check the accuracy of your new AR15, rebuilt Remington 700 or a variety of other platforms. Just be sure the rifle you're using has a 1/7 inch twist (or 1 full revolution per 7 inches), because the Sierra Match King 77 grain bullet gains maximum stabilization with that twist rate.
