Sierra 9290 90 Grain .224 Diameter HPBT MatchKing 500 Count Box

The 22 calibre 90 grain MatcKing was created in response to the increasing demands of Long Range shooters. With the success of the AR-15/M16 style rifles in Long Range competition, the need was felt to maximize the ballistic potential of these rifles. The 90 grain MatchKing® is the final product of a series of tests, covering both accuracy and exterior ballistics, to arrive at the best possible bullet for the Long Range competitor. Designed specifically for the .223 Remington / 5.56x45mm cartridge, the 90 MatchKing is at equally at home in both Match and Service Rifles. Due to the inherent requirements for a bullet of this type, the 90 grain MatchKing is intended for single loading, and is not intended to be fed from a magazine as the overall length of a loaded round will be too long.

Sierra recommends a 6.5” twist barrel for the #9290 22 calibre 90 gr HPBT bullet when pushed at muzzle velocities lower than 2650 fps. In cartridges like the Valkyrie with muzzle velocities above 2650 fps, a 1×7” twist barrel will stabilize the bullet correctly.

This is a 500 count box.  A 50 count box of the 90 grain MatchKing is available here.

Sierra claim a G1 Ballistic Coefficient of .563 @ 2080 fps and above .550 between 1640 and 2080 fps .480 between 1640 and below.
