Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets Review

Let’s Dive into Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets

The Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets are designed for serious long-range shooters seeking unparalleled accuracy in their .223 Remington/5.56x45mm rifles. Manufactured by Sierra Bullets, these bullets are engineered to maximize ballistic potential and deliver consistent performance, making them a favorite among competitive marksmen. Their hollow point boat tail (HPBT) design is a hallmark of match-grade accuracy.

My quest for extreme long-range precision in my AR-15 led me to these bullets. I wanted to push the boundaries of my rifle’s capabilities. Regular ammunition simply wasn’t cutting it for consistent hits at extended distances.

Unboxing the Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets, I immediately noticed the consistent shape and clean finish. The bullets felt substantial and well-made, a promising sign of quality control. Their weight and uniformity hinted at the precision I was hoping for.

I considered Berger 90 grain VLD Target bullets and Hornady 88 grain ELD Match bullets before settling on the Sierra Bullets. While both alternatives had their merits, the Sierra Bullets‘ reputation for consistent performance in AR-15 platforms, coupled with their slightly lower price point, swayed my decision. I also had good results in the past with Sierra Bullets projectiles.

My initial impression was one of excitement tempered with a dose of realism. These bullets promised exceptional accuracy, but I knew achieving optimal performance would require careful load development and meticulous attention to detail. The potential was there, and I was eager to unlock it.

Real-World Testing: Putting Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets to the Test

First Use Experience

My first test of the Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets took place at my local shooting range, known for its 600-yard capabilities. I wanted to assess their accuracy potential at longer ranges, mimicking conditions encountered in competitive shooting scenarios. The weather was mild, with a slight breeze, providing a reasonable, yet not overly challenging, environment.

Performance was immediately impressive, with tighter groupings compared to standard 55-grain and 77-grain ammunition. The bullets exhibited consistent flight characteristics, and I noted less wind drift than with lighter projectiles. However, the Sierra Bullets are too long to fit in a standard AR-15 magazine, so I was single-loading each round, which is what I expected.

The Sierra Bullets required a noticeably slower powder charge to achieve optimal velocity, which was a learning curve. I initially observed slightly elevated pressures with loads that performed well with lighter bullets, necessitating careful adjustments. This highlighted the importance of consulting load data and starting with conservative powder charges when working with these heavier projectiles.

Extended Use & Reliability

After several months of consistent use, the Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets have proven to be remarkably reliable and consistent. They consistently deliver tight groupings and predictable performance, even with slight variations in weather conditions. I found them to be very sensitive to seating depth.

The bullets show no signs of degradation, maintaining their dimensional accuracy and ballistic performance over time. Their copper jackets have held up well. Careful handling during reloading is necessary to avoid deforming the bullet tips, which can negatively impact accuracy.

Compared to my previous experiences with other match-grade bullets, the Sierra Bullets offer a noticeable improvement in long-range accuracy and wind resistance in my AR-15. While they require more meticulous load development, the results are well worth the effort for serious precision shooters. I achieved sub-MOA groups at 300 yards, which I never saw with lighter bullets in the same rifle.

Breaking Down the Features of Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets

Specifications

The Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets are precision-engineered projectiles designed for long-range accuracy in .223 Remington/5.56x45mm rifles. They feature a hollow point boat tail (HPBT) design and weigh 90 grains each. The manufacturer is Sierra Bullets.

The bullet’s 90-grain weight provides enhanced ballistic coefficient, improving long-range stability and wind resistance. The hollow point design contributes to a more consistent center of gravity, promoting accuracy, but is not intended for rapid expansion in hunting applications. The boat tail further enhances ballistic efficiency.

Performance & Functionality

The Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets excel in delivering exceptional long-range accuracy and consistent ballistic performance. They are optimized for use in rifles with appropriate twist rates. They are not designed to be fed from a magazine.

The strengths of these bullets lie in their precision manufacturing, consistent weight, and aerodynamic design, all of which contribute to tight groupings and predictable trajectories. One potential weakness is that their length requires a faster twist rate (1:7 or 1:6.5) for optimal stabilization in flight. They also cannot be reliably loaded into standard AR-15 magazines due to their length.

These bullets exceed expectations for long-range accuracy in an AR-15 platform. They deliver consistent performance at extended distances, allowing shooters to achieve sub-MOA accuracy with carefully developed loads. However, they do require some expertise in reloading and a rifle optimized for heavier projectiles.

Design & Ergonomics

The Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets are designed with a focus on functionality and accuracy. They do not require any handling from the user other than loading them into cartridges. Their consistent shape and weight contribute to their reliable performance.

The build quality is excellent, with consistent dimensions and a smooth copper jacket. The hollow point is precisely formed, and the boat tail is clean and well-defined. Their weight provides a substantial feel, inspiring confidence in their ballistic capabilities.

Durability & Maintenance

As projectiles, the Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets are single-use items. Their durability is primarily a factor during the reloading process and in maintaining their shape during storage. Care should be taken to avoid deforming the bullet tips or damaging the copper jackets.

Minimal maintenance is required other than proper storage in a cool, dry place to prevent oxidation of the copper jackets. Gentle handling during reloading will help preserve their dimensional accuracy and ballistic performance. Careful transportation will help avoid deforming them.

Accessories and Customization Options

The Sierra Bullets .22 Caliber 90 Grain HPBT MatchKing Rifle Bullets themselves do not have accessories. However, they are compatible with various reloading components and techniques. These include different powders, primers, and cartridge cases to fine-tune their performance.

Different seating depths and crimping methods can be used to optimize accuracy in specific rifles. The bullets are also compatible with various bullet seating dies and reloading presses.
