Sierra MatchKing X (MKX) Rifle Bullets 7mm/.284 cal .284" 175 gr HPBT MATCH 100/ct

The Sierra MatchKing X (MKX) 7mm/.284 caliber 175-grain rifle bullets split the difference between pure match ammo and hunting rounds—without forcing you to compromise on either front. Built on the same proven ogive as Sierra's legendary MatchKing, these hollow point boat tail projectiles maintain identical external dimensions, meaning you can load them in the same dies and achieve the same point-of-aim as your match ammunition. That's a genuine advantage if you shoot the same rifle for both precision target work and field hunting.

The real draw here is ballistic performance. At 0.597 G1, the MKX carries a high ballistic coefficient that keeps energy and velocity stable downrange—critical for long-range work where wind drift and bullet drop demand consistency. The hollow point design is engineered to expand reliably at the velocities typical of extended-range hunting, giving you terminal performance that a solid match bullet simply won't deliver. Sierra packed a lot of thought into these; they're not a compromise in the traditional sense, but rather a dual-purpose round that respects what precision shooters and hunters each need.

A 100-count box gives you enough to develop a solid handload and practice before hunting season, or to work up a single precision load that does double duty. Whether you're shooting paper at distance or pursuing big game in open country, the MKX lets you keep one rifle and one load zeroed and ready.

Frequently Asked Questions

Can I use the same load and seating die for MKX as I do for standard MatchKing?

Yes. The MatchKing X shares the same external dimensions and ogive profile as the original MatchKing, so you can use the same seating die without adjustment and maintain the same point of aim.

Are these bullets suitable for long-range hunting?

Yes. The MKX is designed for reliable expansion at long-range velocities, making it suitable for hunting big game at extended distances while maintaining the ballistic efficiency of a match-grade bullet.

What makes the MKX different from a standard MatchKing?

The MatchKing X has a hollow point design engineered for terminal expansion in game, whereas standard MatchKing bullets are designed purely for target accuracy. The MKX preserves the external ballistics of the MatchKing while adding hunting-appropriate terminal performance.

What's included in a box?

Each box contains 100 loose bullets ready for handloading.
