A Practical Look at the Federal Premium SIERRA MATCHKinG BTHP .338 Lapua Magnum 300 Grain Sierra MatchKing Boat Tail Hollow Point Centerfire Rifle Ammunition GM338LM2 $7.60 Off
My search for reliable, high-performance ammunition for extended-range engagements led me to the Federal Premium SIERRA MATCHKinG BTHP .338 Lapua Magnum 300 Grain Sierra MatchKing Boat Tail Hollow Point Centerfire Rifle Ammunition GM338LM2 $7.60 Off. As an equipment specialist with over a decade of experience in diverse environments, I understand the critical role precision and consistency play, especially when pushing the boundaries of ballistic performance. The .338 Lapua Magnum cartridge itself is a testament to robust design for demanding applications, and Federal’s Gold Medal line consistently delivers on its promise of quality. I was particularly drawn to the 300-grain Sierra MatchKing projectile for its reputation and the specifications promising a stable, flat trajectory.
The initial trigger for this acquisition was a need for greater accuracy at distances I was previously struggling to achieve reliably with my current .338 Lapua Magnum setup. While I have other ammunition options in my arsenal, none offered the specific combination of bullet weight, ballistic coefficient, and manufacturer pedigree that this particular Federal Premium load promised. The idea was to find a round that would consistently group tighter, allowing for more predictable wind calls and ultimately, more effective shots at longer ranges.
Upon receiving the ammunition, my first impression was one of professional packaging and meticulous attention to detail. The cases were uniform, the bullets seated perfectly, and there was an undeniable sense of quality control. It’s a tangible feeling you develop over years of handling countless types of gear – a certain confidence that comes from holding something crafted with precision. I’d briefly considered another premium manufacturer’s offering in a similar weight class, but ultimately, Federal’s reputation for match-grade consistency tipped the scales. My initial reaction was one of quiet satisfaction, a sense of having found a potentially significant upgrade for my long-range endeavors.
Real-World Testing: Putting Federal Premium SIERRA MATCHKinG BTHP .338 Lapua Magnum 300 Grain Sierra MatchKing Boat Tail Hollow Point Centerfire Rifle Ammunition GM338LM2 $7.60 Off to the Test
First Use Experience
My primary testing ground for this Federal Premium SIERRA MATCHKinG BTHP .338 Lapua Magnum 300 Grain Sierra MatchKing Boat Tail Hollow Point Centerfire Rifle Ammunition GM338LM2 $7.60 Off was a remote mountain range known for its challenging wind conditions and considerable distances. I set up at my usual 100-yard zero point, then progressively moved to 500, 1000, and ultimately 1500-yard targets. The initial experience was immediately promising; the rifle cycled flawlessly, and the first shots at 100 yards were tight clusters, well within the sub-MOA expectations for this caliber and ammunition.
Under variable wind conditions ranging from calm to gusty crosswinds, the 300-grain Sierra MatchKing projectile demonstrated exceptional stability. Its ballistic coefficient of 0.768 (G1) and 0.387 (G7) proved its worth, translating into predictable bullet drop and significantly less wind drift than I’ve experienced with lighter offerings. Even after a long day at the range with repeated firing, there was no discernible degradation in performance or any indication of issues with the ammunition itself. The muzzle velocity, consistently around 2580 ft/s, provided ample energy, registering a substantial 4434 ft-lbs at the muzzle, which is crucial for maintaining downrange effectiveness.
Ease of use was, as expected for factory-loaded match ammunition, completely intuitive. There’s no learning curve involved; you simply load the cartridge, chamber it, and fire. The centerfire primer ignition was consistent, and the Federal brass cases ejected cleanly after each shot. My only minor surprise was how visibly reduced the muzzle flash was compared to some other .338 Lapua Magnum loads I’ve used, which I attribute to the specially formulated propellant Federal employs.
Extended Use & Reliability
Over several months of regular use, both at controlled range environments and during more rugged field excursions where conditions were less forgiving, this Federal Premium ammunition has held up admirably. I’ve experienced no failures to feed, fire, or eject across multiple shooting sessions, reinforcing the reliability expected from Federal’s Gold Medal line. The ammunition has been exposed to dust, temperature fluctuations, and even a light drizzle on occasion, with absolutely no impact on its performance or accuracy.
Durability, in the context of ammunition, means consistency. The most significant indicator of this round’s longevity and sustained performance is its ability to produce consistent groups. Even after storing boxes for extended periods and subjecting them to varying environmental conditions, the accuracy remained remarkably stable. I have noticed no physical degradation of the rounds, such as bullet set-back or case deformation, which speaks volumes about the quality of the manufacturing process.
Maintenance and care for ammunition are primarily about proper storage, and these cartridges are no different. Keeping them in a cool, dry place, away from direct sunlight, is paramount, and this is standard practice for any serious shooter. Compared to reloaded ammunition, which can vary wildly in consistency, this factory-loaded match round offers a level of predictable performance that is difficult and time-consuming to replicate. While some premium hand-loads might edge it out in niche applications, for consistent, out-of-the-box accuracy, this Federal Premium load is difficult to beat.
Breaking Down the Features of Federal Premium SIERRA MATCHKinG BTHP .338 Lapua Magnum 300 Grain Sierra MatchKing Boat Tail Hollow Point Centerfire Rifle Ammunition GM338LM2 $7.60 Off
Specifications
The Federal Premium SIERRA MATCHKinG BTHP .338 Lapua Magnum 300 Grain Sierra MatchKing Boat Tail Hollow Point Centerfire Rifle Ammunition GM338LM2 $7.60 Off comes packed with specifications that are crucial for long-range precision. It features a 300-grain Sierra MatchKing Boat Tail Hollow Point (BTHP) bullet, renowned for its aerodynamic profile and inherent stability in flight. The cartridge case is made of brass, a standard for its durability and compatibility with firearm actions. Muzzle velocity is stated at 2580 ft/s, providing a strong foundation for long-range trajectory.
The G1 Ballistic Coefficient of 0.768 and G7 Ballistic Coefficient of 0.387 are critical figures for long-range shooters. These numbers directly translate into how well the bullet retains its velocity and resists aerodynamic drag, meaning less holdover and reduced wind drift. The 20-round box packaging is standard for premium ammunition, offering a manageable quantity for range sessions or specific field applications. The centerfire primer style ensures reliable ignition.
These specifications are not just numbers; they are the building blocks of predictable performance. A higher ballistic coefficient, like the one offered here, means the bullet travels further and flatter, making your calculations simpler and your shots more precise, especially at distances exceeding 1000 yards. The 300-grain weight also contributes to momentum, helping the projectile punch through wind and maintain its path more effectively than lighter bullets. This ammunition is specifically designed for Target Shooting, emphasizing accuracy and consistency above all else. It is important to note that this ammunition is Not Lead-Free.
Performance & Functionality
In terms of its primary function – delivering precise and consistent projectiles downrange – this Federal Premium ammunition performs exceptionally well. The accuracy is outstanding; consistently achieving sub-MOA groups at extended distances is not uncommon, and with a well-tuned rifle, even smaller groups are achievable. The boat-tail design paired with the hollow point cavity in the Sierra MatchKing bullet ensures excellent aerodynamic stability, translating into predictable bullet trajectory even in challenging wind conditions.
The strengths of this ammunition are its superior accuracy, consistent ballistic performance, and high downrange energy. The 300-grain Sierra MatchKing bullet is a proven performer, and Federal’s meticulous loading process ensures each round behaves predictably. A minor weakness, if it can be called that for match ammunition, is the price point; while the performance justifies the cost for serious long-range shooters, it is certainly an investment. For its intended purpose of target shooting and long-range precision, it exceeds expectations and reliably delivers the performance needed for challenging shots.
Design & Ergonomics
The design of this ammunition focuses entirely on ballistic efficiency and consistent ignition. The Sierra MatchKing bullet is a testament to meticulous engineering, featuring a precisely controlled hollow point and a boat tail that minimizes aerodynamic drag.

The “ergonomics” of ammunition are more about how it integrates with the firearm and the shooter’s process. This round is designed for seamless feeding and extraction from compatible firearms chambered in .338 Lapua Magnum. The benchrest-quality Gold Medal primer contributes to consistent ignition, which is vital for repeatable accuracy. There is no specific “grip” or “feel” to ammunition beyond the visual confirmation of quality; however, the uniformity of the rounds instills confidence in their handling and function.
Durability & Maintenance
Ammunition, by its nature, is designed for single use and subsequent discard of the casing. Therefore, “durability” here refers to its shelf-life and resistance to environmental degradation when stored properly. When kept in a cool, dry environment, this Federal Premium ammunition can maintain its peak performance for many years.
Maintenance for ammunition primarily involves proper storage and handling. Keeping the rounds in their original box and avoiding exposure to extreme temperatures or moisture will ensure their longevity. There are no user-serviceable parts; once fired, the casing is typically reloaded or discarded. Potential concerns are minimal, assuming responsible storage, and any failures would likely stem from improper handling or storage rather than inherent flaws in the ammunition’s construction.
Accessories and Customization Options
This product is ammunition, so it does not come with traditional “accessories” in the way a firearm or piece of gear might. However, its primary “complement” is the firearm itself – a rifle chambered in .338 Lapua Magnum. The ammunition is designed to work optimally with rifles specifically built for this powerful cartridge, often those intended for long-range precision shooting.
There are no “customization options” for the ammunition itself, as it is a precisely manufactured component. However, the rifle it is used in can certainly be customized with optics, stocks, and other accessories to optimize the shooting experience. The key is ensuring your firearm is properly matched to this high-performance round. Federal also offers various other loads within their Gold Medal line, but this specific configuration offers a unique blend of weight and ballistic performance.
