I was searching for a bullet that could reliably dispatch medium-sized game at varying distances. I wanted something more than just accuracy; I needed a projectile that would transfer energy effectively and ethically.
Opening the box, I was immediately impressed with the uniformity of the bullets. They felt solid and well-constructed, suggesting a high level of quality control during manufacturing.
Compared to the Hornady ELD-X and the Nosler Ballistic Tip, these Sierra GameKing bullets seemed to strike a balance between match-grade precision and hunting-specific terminal ballistics. The ELD-X is known for extreme long-range performance, while the Ballistic Tip emphasizes rapid expansion; I was hoping the GameKing would offer a versatile middle ground. My initial impression was positive; these bullets looked promising for a variety of hunting scenarios.
Real-World Testing: Putting Sierra Bullets .243 Caliber 90 Grain BTHP Tipped GameKing 100 Rifle Bullets to the Test
First Use Experience
I first tested these bullets at my local shooting range, zeroing my .243 Winchester rifle at 100 yards. The range provided a controlled environment to assess accuracy and consistency.
Conditions were relatively mild, with a slight breeze and clear skies. This allowed for optimal visibility and minimal environmental impact on bullet trajectory.
The bullets were easy to load and chamber, and I quickly found a load that my rifle seemed to like. I didn’t need extensive load development to achieve acceptable accuracy.
The only surprise was the point of impact shift compared to my previous load using a different bullet weight. This required a quick adjustment to my scope settings, but it wasn’t unexpected.
Extended Use & Reliability
After several months of use, including multiple range sessions and a whitetail deer hunt, the Sierra GameKing bullets have proven to be quite reliable. They’ve consistently grouped well and performed as expected.
I haven’t noticed any signs of significant wear and tear on the bullets themselves. They’ve remained consistent in weight and dimensions, contributing to consistent accuracy.
Maintenance is straightforward; as with any reloading component, proper storage in a cool, dry place is key. I’ve used both a tumbler and ultrasonic cleaner to clean the brass after firing.
Compared to my previous hunting bullets, the Sierra GameKing has impressed me with its combination of accuracy and terminal performance. It’s outperformed some in terms of group size and has proven more effective than others on game animals.
