Sierra Matchking Rifle Bullets 7Mm / .284 Cal .284" 183 Gr Hpbt Match 500/C

The Sierra Matchking 7mm 183 grain HPBT rifle bullets are engineered for precision shooters who demand match-grade accuracy at distance. Each box contains 500 rounds of .284 caliber ammunition built to exacting tolerances, making these bullets the choice for competitive target shooting, long-range rifle work, and precision load development. The 183 grain weight in 7mm bore diameter balances velocity retention with stable flight, delivering the consistency that separates tight groups from scattered shots downrange.

Sierra's Matchking design centers on repeatable, predictable performance. The 27 caliber ogive profile—elongated for a sleek ballistic shape—works with a proprietary final pointing operation to maximize ballistic coefficient and minimize wind drift. The bearing surface transitions to the ogive at a 1.5 degree angle that mirrors precision match rifle chamber throats, ensuring bullet-to-bore alignment that reduces run-out and tightens groups. These details matter when you're chasing accuracy at 300, 600, or 1,000 yards.

Important: Sierra Matchking bullets are optimized for target and competition shooting, not hunting. Their design prioritizes accuracy over expansion and is not recommended for big game or varmint hunting where controlled, reliable bullet performance is essential. These 183 grain .284 caliber bullets require a barrel twist rate of 1-in-8 inches or faster to stabilize properly in flight.

If you're loading ammunition for precision rifle competition, distance benchrest, or dedicated long-range target work with a 7mm cartridge, these match-grade bullets deliver the consistency you need to shoot your best. Reload 500 rounds per box for a productive session at the range or during load development.
