The Sierra 9290 MatchKing 22-caliber 90-grain hollow point boat tail bullet is engineered for long-range precision shooting and competition use. Developed specifically for the .223 Remington and 5.56x45mm cartridge, this 500-count box delivers the match-grade accuracy that competitive shooters and precision rifle builders demand. The 90-grain MatchKing has earned its reputation across AR-15 platforms in both match and service rifle competitions, where long-range performance and consistency matter most.
These bullets are optimized for accuracy and ballistic performance rather than hunting applications. While many reloaders use MatchKings for varmint work, Sierra notes they're not designed to provide the reliable expansion of their purpose-built varmint bullets at equivalent velocities. The hollow point boat tail profile delivers the external ballistics precision that separates match-winning loads from routine ones. Whether you're building competition ammo or pushing the effective range of your precision rifle, this bullet addresses the specific demands of long-range shooting where flight path stability and shot-to-shot consistency are non-negotiable.
Important: These bullets are designed for single-loading and are not intended to be fed from a magazine. Barrel twist matters with this projectile—Sierra recommends a 6.5-inch twist minimum when running velocities below 2650 fps, and a 1-in-7-inch twist for faster cartridges like the Valkyrie at higher velocity. Verify your barrel twist and load data before beginning your handload development.
| Caliber | .22 (5.56mm) |
| Weight | 90 grains |
| Style | Hollow Point Boat Tail (HPBT) |
| Box Quantity | 500 bullets |
| Recommended Cartridge | .223 Remington, 5.56x45mm |
| Barrel Twist (Sub-2650 fps) | 6.5-inch minimum |
| Barrel Twist (2650+ fps) | 1-in-7-inch |
Sierra recommends a 6.5-inch twist barrel when running muzzle velocities below 2650 fps. If you're using a faster cartridge like the .224 Valkyrie with velocities above 2650 fps, a 1-in-7-inch twist will stabilize the bullet correctly.
No. The 90-grain MatchKing is designed for single-loading and is not intended to be fed from a magazine. These are purpose-built for precision loading practices where you control each round into the chamber.
MatchKing bullets are not recommended for most hunting applications. While they're used for varmint hunting, they won't deliver the same reliable expansion that Sierra's dedicated varmint bullets provide at equivalent velocities. Consider Hornet Blitz or Varminter bullets if hunting is your primary goal.
This bullet is designed specifically for the .223 Remington and 5.56x45mm cartridge. It's equally at home in match rifles and service rifle platforms like the AR-15.
