For years, I’ve relied on consistent, dependable ammunition for my hunting pursuits, and the HSM Ammunition Game King 7mm Remington Magnum 140 Grain Sierra Gameking Brass Cased Centerfire Rifle Ammunition
HSM-7mmMAG-21-N $6.40 Off has earned a place in my hunting vest. This ammunition, born from a collaboration between HSM Ammunition and Sierra Bullets, is specifically engineered for the demanding conditions of long-range hunting. The core of its design lies in the Sierra GameKing/ProHunter line, featuring a Spitzer Boat Tail (SBT) design aimed at delivering superior ballistic performance.
My search for this particular load began with a need for a versatile round for medium to large game in varied western terrains. My previous go-to brand had become inconsistent, and I was actively seeking a reliable alternative that offered both accuracy and terminal ballistics suitable for shots ranging from 200 to 400 yards. I had heard good things about HSM’s commitment to quality control, and the reputation of Sierra bullets for reliable expansion is well-established.
Upon receiving the box, my initial impression was positive. The ammunition felt solid, the brass cases appeared uniform, and the Sierra GameKing bullets were seated consistently. There wasn’t anything flashy about the packaging, but that’s precisely what I look for – straightforward, no-nonsense components ready for hard use. I briefly considered a different grain weight in a more budget-friendly brand, but the specific ballistic profile of this 140-grain GameKing was too appealing to pass up for my intended applications. A small sigh of relief escaped me; it felt like I might have found a new staple for my rifle.

First Use Experience
My initial testing of this ammunition took place on a crisp autumn morning at my local outdoor range. I loaded a magazine into my trusted 7mm Remington Magnum rifle, specifically chosen for its ability to wring the best out of potent cartridges like this one. The conditions were clear, with a slight breeze that I used to gauge wind drift at 300 yards.

HSM-7mmMAG-21-N $6.40 Off fed flawlessly from the rifle’s magazine, with no hiccups or feeding issues. Ejecting spent casings was equally smooth, indicating good case extraction characteristics. Even after firing several rounds in quick succession, the rifle’s action remained clean, and the brass cases showed no signs of excessive pressure or deformation.
I found the handling of this ammunition to be straightforward. It performed as expected, right out of the box, without any need for extensive break-in or adjustment to my shooting technique. The consistency in seating depth and overall build quality of each cartridge was immediately apparent, setting a good precedent for its field performance.
Extended Use & Reliability
Over the course of two hunting seasons, this specific ammunition has proven its mettle. I’ve used it for everything from pronghorn hunts in open country to elk stalks in dense timber, often facing unpredictable weather. It has been exposed to dust, occasional light rain, and significant temperature fluctuations without any noticeable degradation in performance.
Durability has been excellent; I haven’t encountered any cracked cases or visibly damaged bullets, even after carrying loaded magazines on rough terrain. The brass cased construction ensures that these rounds can be reloaded, a significant plus for long-term cost-effectiveness. Compared to some other factory loads I’ve used, the consistency of velocity and accuracy has remained remarkably high, even after months of being stored in my hunting pack.
Maintenance is as simple as keeping the ammunition dry and clean, which is standard practice for any firearm owner. The boxer primer design makes them easy to reload, a feature I appreciate for its sustainability and cost savings. I haven’t had to replace any components or perform specialized cleaning due to this ammunition, which is a testament to its quality manufacturing.
Breaking Down the Features of **HSM Ammunition Game King 7mm Remington Magnum 140 Grain Sierra Gameking Brass Cased Centerfire Rifle Ammunition
HSM-7mmMAG-21-N $6.40 Off**
Specifications
This ammunition comes chambered for the 7mm Remington Magnum caliber, a proven performer for medium to large game. Each box contains 20 rounds, providing a practical quantity for a hunting trip or range session. The core of each projectile is the 140 grain Sierra GameKing bullet, specifically a Spitzer Boat Tail (SBT) design.
This bullet configuration is chosen for its ballistic efficiency and aerodynamic properties, contributing to a flatter trajectory and reduced wind drift. The cartridge case material is brass, a classic and reliable choice known for its durability and reloadability. HSM Ammunition emphasizes that this is non-corrosive, boxer-primed ammunition, housed in reloadable brass cases.
The specifications of this ammunition directly translate into practical advantages for the shooter. The 140-grain weight strikes an excellent balance between velocity and bullet mass for the 7mm Remington Magnum, offering effective energy transfer. The SBT design is crucial for long-range accuracy, minimizing aerodynamic drag and thus extending the effective range of the cartridge. The brass casing is a standard feature for quality centerfire rifle ammunition, allowing for safe and repeatable firing, along with the valuable option of future reloading.
Performance & Functionality
In terms of its primary job – delivering accurate and effective projectile delivery – this ammunition truly shines. The Sierra GameKing bullet is designed for controlled expansion and deep penetration, which is paramount for humane harvests. I’ve witnessed reliable performance on various game animals, with the bullet creating significant wound channels while minimizing excessive meat damage, especially when placed correctly.
Its strongest attribute is undoubtedly its long-range accuracy. The combination of the 7mm Remington Magnum’s inherent capabilities and the ballistically optimized Sierra GameKing bullet results in tight groups at extended distances. This allows hunters to ethically engage targets that might otherwise be out of reach. A potential area for improvement, though minor, is that the bullet’s construction is optimized for a wide range of game; for extremely tough hides or very large game at close range, a heavier, bonded bullet might be preferred by some. However, for its intended purpose and typical whitetail or pronghorn scenarios, it performs exceptionally well.
Design & Ergonomics
The design of this ammunition is focused purely on function and performance. The jacketed soft-point bullet is designed to initiate expansion reliably upon impact with game tissue. The Spitzer Boat Tail (SBT) design isn’t just for ballistics; it also contributes to a streamlined profile that aids in smooth feeding from various rifle actions.
The brass case offers a familiar and trustworthy feel, fitting well within standard SAAMI specifications for consistent chambering. The overall construction feels robust and precisely manufactured, as one would expect from a partnership between two reputable companies. There’s no learning curve here; it’s designed to be used immediately and reliably.
Durability & Maintenance
Given its intended use, this ammunition is built for single-use effectiveness in the field, with the potential for reloading of the brass case. The bullets are designed to perform their terminal ballistics mission upon impact. The brass cases, however, are durable and capable of multiple reloads if properly handled and cared for.
Maintenance is minimal. Keeping the cartridges clean and dry is the primary concern. If reloaded, standard brass case care – annealing, resizing, and cleaning – would apply. I haven’t experienced any issues with corrosion or degradation of the cases during normal storage, even in humid conditions.
Accessories and Customization Options
This particular offering from HSM Ammunition is sold as complete cartridges and does not come with separate accessories. The primary form of “customization” or extended use comes from the reloadable, non-corrosive, boxer primed brass cases. This allows dedicated handloaders to use the same high-quality brass for their own hand-loaded hunting or target rounds.
The Sierra GameKing bullet itself is a known entity, and its performance profile is well-documented. While there are no additional optics or specialized attachments to consider with ammunition, the reloader can experiment with different powder charges and seating depths to fine-tune performance in their specific rifle, though the factory load is optimized for broad effectiveness.

Who Should Buy **HSM Ammunition Game King 7mm Remington Magnum 140 Grain Sierra Gameking Brass Cased Centerfire Rifle Ammunition
HSM-7mmMAG-21-N $6.40 Off**?
This ammunition is ideally suited for the dedicated hunter who operates a 7mm Remington Magnum rifle and frequently encounters opportunities for shots at medium to longer distances. It’s a prime choice for those pursuing game like pronghorn, deer, and elk in open terrain or mountainous regions where precise shot placement at range is critical for success and ethical hunting. Enthusiasts who appreciate the craft of reloading will also find the reloadable brass cases to be a significant advantage.
Conversely, individuals seeking bulk ammunition for high-volume target practice at very close ranges might find the price-per-round and bullet construction less ideal for that specific purpose. Hunters who exclusively pursue extremely large, thick-skinned game at very close quarters might want to explore heavier, bonded projectile options, though this round is still highly capable. For anyone already invested in a good rifle chambered in 7mm Remington Magnum and looking for a reliable, accurate hunting load, this HSM Ammunition product is a strong contender.
