The Sierra Bullets .22 Caliber 55 Grain FMJ GameKing Rifle Bullets: Final Thoughts from Me
For years, I’ve relied on quality components to achieve consistent results, whether I’m working in a meticulous lab, a noisy workshop, or out in the field. When I needed reliable .22 caliber projectiles for a specific reloading project that demanded consistent terminal performance without excessive meat damage, the Sierra Bullets .22 Caliber 55 Grain FMJ GameKing Rifle Bullets immediately came to mind. Sierra has a long-standing reputation for precision, and this particular offering promised a balance of robust construction and predictable expansion. I remember poring over ballistics tables, looking for something that wouldn’t fragment too early but would still be effective. My previous experience with their GameKing line in larger calibers had been positive, so the decision to try this 55-grain FMJ was a logical next step. I had briefly considered some heavier monolithic bullets for pure penetration, but my objective here was controlled expansion and weight retention. My initial impression upon receiving the box was one of solid, no-nonsense manufacturing; the bullets felt substantial and uniform.
Real-World Testing: Putting Sierra Bullets .22 Caliber 55 Grain FMJ GameKing Rifle Bullets to the Test
First Use Experience
My initial testing took place on a crisp autumn afternoon at my local shooting range, specifically on my dedicated reloading bench set up for fine-tuning loads. I was working with a .223 Remington chambered rifle known for its accuracy, and the goal was to establish reliable loads for general plinking and the occasional varmint control, where preserving pelt and meat is important. I carefully loaded each cartridge, paying close attention to powder charges and seating depth, and the Sierra Bullets .22 Caliber 55 Grain FMJ GameKing Rifle Bullets seated with satisfying uniformity. The first shots were incredibly promising, producing tight groups at 100 yards with minimal fuss.
Even after several hours of consistent firing and loading, the bullets fed flawlessly through my rifle’s action. Their consistent weight and shape contributed significantly to predictable cycling and ejection. I didn’t encounter any feeding issues or bullet deformation during this initial range session, which is always a good sign with any new component. The lack of overt signs of stress or damage after numerous rounds was a testament to their build quality.
Extended Use & Reliability
Over the following months, these bullets became a staple for many of my shooting activities. I’ve used them in various weather conditions, from humid summer days to colder, drier fall mornings, and their performance remained remarkably consistent. They’ve been loaded and fired hundreds of times, both from my bench-rest setup and during more informal range sessions.
Despite being handled frequently and subjected to the normal bumps and jostles of transport, the bullets show no significant signs of wear. There are no visible cracks in the jacket, and their weight and form have remained true. Cleaning my rifle after using these projectiles is straightforward, with minimal copper fouling compared to some other bullet types I’ve experimented with. Their reliability in terms of consistent accuracy and terminal performance over an extended period is what truly sets them apart for me.
Breaking Down the Features of Sierra Bullets .22 Caliber 55 Grain FMJ GameKing Rifle Bullets
Specifications
The Sierra Bullets .22 Caliber 55 Grain FMJ GameKing Rifle Bullets come as a 100-pack bulk offering, which is a convenient quantity for serious reloaders. Each projectile is designed to a .224 inch caliber specification, fitting standard .223 Remington and 5.56 NATO chambers. The 55 grain weight strikes a common balance for this caliber, suitable for a wide range of applications.
These bullets feature a Full Metal Jacket (FMJ) construction, meaning a copper jacket completely encases the lead core. This design is crucial for preserving meat and pelt during impact, as it significantly reduces fragmentation. The uniform shape and the boat tail design contribute to improved ballistic coefficients, leading to flatter trajectories and better aerodynamic stability.
Performance & Functionality
In terms of core function, these bullets perform exceptionally well for their intended purpose. They are engineered to retain significant weight upon impact, offering controlled terminal performance rather than explosive fragmentation. This makes them ideal for varmint hunting or situations where minimizing collateral damage is a priority.
Their primary strength lies in their consistent weight retention and predictable expansion at medium velocities. However, they are a non-expanding bullet by design, meaning their terminal effect is less dramatic than dedicated expanding projectiles. While excellent for their intended role, they are not designed for deep penetration against heavy, tough-skinned game.
Design & Ergonomics
The Sierra Bullets .22 Caliber 55 Grain FMJ GameKing Rifle Bullets exhibit a classic, no-nonsense design. The jacket is smoothly formed and consistently applied, ensuring good seating and a uniform surface for gas sealing. Their overall feel is one of precision manufacturing, with no visible imperfections that could negatively impact accuracy.
The boat tail design is a key ergonomic feature, reducing drag and improving stability in flight. This translates to easier reloading, as they tend to align smoothly with case mouths during the seating process. The full metal jacket is also smooth, minimizing potential issues with feeding in semi-automatic actions.
Durability & Maintenance
The durability of these bullets is excellent for their class. The heavy full metal jacket is designed to protect the projectile and maintain its integrity through the bore and upon impact. This robust construction means they are not prone to deformation during handling or reloading.
Maintenance primarily involves careful storage to prevent corrosion or damage to the copper jacket. Keeping them in their original packaging or a suitable component storage system is recommended. There are no complex maintenance procedures required for the bullets themselves, as they are designed for single use.
Accessories and Customization Options
As components for reloading, these bullets are designed to be used with standard reloading equipment and powders. Sierra Bullets do not typically include accessories with their bullet lines. However, the 100-pack bulk quantity is a convenient option for those who reload regularly.
These projectiles are designed to be compatible with a wide range of reloading dies and presses. Their uniform dimensions mean they will work well with most standard case preparation and bullet seating tools. There are no specific customization options for the bullets themselves, as they are manufactured to precise specifications.

Who Should Buy Sierra Bullets .22 Caliber 55 Grain FMJ GameKing Rifle Bullets?
These bullets are an excellent choice for recreational shooters, varmint hunters, and reloaders who prioritize accuracy and controlled terminal performance.
