Let’s Dive into Sierra Bullets .308 Caliber 165 Grain Tipped GameKing 100 Rifle Bullets
The Sierra Bullets .308 Caliber 165 Grain Tipped GameKing 100 Rifle Bullets represent a sweet spot for .308 Winchester reloaders aiming for both accuracy and terminal performance on medium to large game. These bullets, manufactured by Sierra, boast a tipped design for enhanced ballistic coefficient (BC) and reliable expansion. They promise to deliver consistent results whether you’re honing your skills at the range or stalking deer in the backcountry.
My quest for the perfect .308 bullet began years ago, driven by a desire to create handloads that could consistently take down whitetail deer with ethical, one-shot kills. I was tired of inconsistent performance from factory ammunition and wanted to tailor a load specific to my rifle and hunting style. The GameKing series has always been on my radar, so I was eager to test the tipped version.
Upon receiving the box of Sierra Bullets .308 Caliber 165 Grain Tipped GameKing 100 Rifle Bullets, my initial impression was positive; the bullets were uniformly shaped and visually inspected, exhibiting the kind of quality control I expect from Sierra. The polymer tips were precisely seated, and the boat tail design was clean and sharp. The packaging securely held the bullets in place, preventing any damage during shipping.
Compared to other popular .308 bullets like the Hornady ELD-X or the Nosler Partition, the Sierra Tipped GameKing offered a compelling balance of price and performance. The ELD-X is known for its exceptional BC, but can be pricier. The Nosler Partition is a legendary controlled-expansion bullet, but it does not always group as tightly as a match-grade bullet at longer ranges. I chose the Sierra Bullets .308 Caliber 165 Grain Tipped GameKing 100 Rifle Bullets hoping for a good compromise of ballistic performance, controlled expansion, and reasonable cost.
My first impression was one of cautious optimism. I was eager to load them up and see how they performed in my rifle. The promise of improved BC and consistent expansion was certainly appealing, but I knew that the proof would be in the groups on the target and the results in the field.
Real-World Testing: Putting Sierra Bullets .308 Caliber 165 Grain Tipped GameKing 100 Rifle Bullets to the Test
First Use Experience
My first test of the Sierra Bullets .308 Caliber 165 Grain Tipped GameKing 100 Rifle Bullets was at my local shooting range, a 100-yard outdoor facility. I was testing a batch of handloads developed using Hodgdon Varget powder and carefully-selected cases. I aimed to determine the optimal powder charge for the best accuracy. The weather was slightly overcast with a light breeze, providing fair conditions.
The bullets performed admirably, consistently grouping around 0.75-1 inch at 100 yards with my tuned load. I was particularly impressed with the consistency of the bullet seating depth and the ease with which they fed into the chamber. There were no noticeable issues with bullet instability or excessive recoil.
Extended Use & Reliability
After several months of use, the Sierra Bullets .308 Caliber 165 Grain Tipped GameKing 100 Rifle Bullets have proven to be remarkably reliable. I’ve used them in temperatures ranging from below freezing to well above 80 degrees Fahrenheit, with no significant change in performance. The bullets have held up well to repeated handling during the reloading process, showing no signs of deformation or damage.
I did notice that after a few reloads, the brass cases tended to stretch more readily compared to when using heavier bullets. This observation suggests that the 165-grain bullet, propelled at higher velocities, might create slightly increased pressure. However, this has not significantly affected the lifespan of my brass. Maintenance primarily involves inspecting the bullets for any visible defects before loading.
Compared to my previous experience with the Barnes TTSX, a solid copper bullet, the Sierra Tipped GameKing offered more consistent accuracy across a broader range of powder charges in my rifle. I am consistently impressed with the performance of the Sierra Bullets .308 Caliber 165 Grain Tipped GameKing 100 Rifle Bullets.
Breaking Down the Features of Sierra Bullets .308 Caliber 165 Grain Tipped GameKing 100 Rifle Bullets
Specifications
- Bullet Type: Flat Base Tipped (FBT). This design combines a flat base for consistent ignition with a polymer tip for improved aerodynamics and expansion.

- Projectile Caliber: .308 Caliber. Standard .308 diameter, compatible with any .308 Winchester or .308-based cartridge rifle.
- Bullet Quantity: 100 Bullet. A standard quantity for reloading, allowing for ample testing and load development.
- Barrel Twist Rate: 1-9. This is the recommended twist rate to stabilize the bullet.
- Country of Origin: USA. This ensures higher quality control.
These specifications matter because they directly influence the bullet’s performance in terms of accuracy, trajectory, and terminal ballistics. The FBT design aids stability and expansion. The 165-grain weight provides a good balance of velocity and energy.
Performance & Functionality
The Sierra Bullets .308 Caliber 165 Grain Tipped GameKing 100 Rifle Bullets perform their job exceptionally well. Accuracy is excellent, consistently producing sub-MOA groups in my rifle with a carefully tuned load. The bullets exhibit reliable expansion on game, delivering quick and humane kills.
The primary strength of these bullets is their ability to combine accuracy and terminal performance in a single package. The main weakness is that ballistic coefficient isn’t as high as some of the newer, more streamlined designs, so performance in windy conditions can be more affected. However, the bullets meet and exceed expectations for their intended purpose.
Design & Ergonomics

The polymer tips are securely seated and do not appear prone to damage. The boat tail design aids in easy seating and improves ballistic coefficient.
Durability & Maintenance
These bullets are essentially a consumable item, but their construction suggests they will hold up well during the reloading process and in storage. Proper storage in a dry environment is recommended to prevent corrosion.
The bullet’s design ensures it will perform reliably until it impacts the target, making its lifespan directly related to its use. No significant maintenance is required.
Accessories and Customization Options
The bullets themselves do not require any accessories. However, they are intended to be used with reloading equipment, including:
- Reloading Dies: .308 Winchester reloading dies are essential for seating the bullets in the case.
- Powder: Selecting the right powder and charge is crucial for achieving optimal performance.
- Primers: High-quality primers ensure consistent ignition.
The bullets are compatible with a wide range of .308 Winchester rifles and reloading components. The main customization option is optimizing the powder charge and seating depth to achieve the best accuracy in a particular rifle.
