Sierra Bullets 338 Caliber 215 Grain SBT GameKing Rifle Bullets Review

Let’s Dive into Sierra Bullets 338 Caliber 215 Grain SBT GameKing Rifle Bullets

The Sierra Bullets 338 Caliber 215 Grain SBT GameKing Rifle Bullets are designed with the .338 Winchester Magnum in mind. These bullets from Sierra Bullets promise controlled expansion, deep penetration, and accuracy at long range. They aim to deliver a reliable performance on medium to elk-sized game.

For years, I’ve struggled to find a bullet that balances reliable expansion with the ability to reach out and touch game at longer distances, especially in my .338 Winchester Magnum. Most bullets either fragmented too quickly or penciled through without delivering sufficient energy. I was hoping these would be the solution.

My first impression upon unboxing was positive. The bullets looked uniform, clean, and well-made, a testament to Sierra Bullets’s reputation. The Spitzer Boat Tail (SBT) design was clearly visible, suggesting good aerodynamic properties.

Compared to the Nosler Partition and Barnes TSX, the Sierra GameKing offered a potentially better blend of expansion and penetration at a lower price point. The Partition is known for excellent penetration but can be overkill on smaller game, while the TSX sometimes requires higher velocities for optimal expansion. I picked the GameKing hoping for that “sweet spot”.

Initially, I was excited but also cautiously optimistic. While I’d heard good things about Sierra Bullets, I knew the proof would be in their performance downrange and in the field. The price was reasonable, and the design seemed promising.


Real-World Testing: Putting Sierra Bullets 338 Caliber 215 Grain SBT GameKing Rifle Bullets to the Test

First Use Experience

My first test was at the local shooting range, zeroing my rifle at 100 yards and then stretching out to 300. I wanted to gauge the accuracy and consistency of the Sierra Bullets 338 Caliber 215 Grain SBT GameKing Rifle Bullets. The conditions were mild, with a slight breeze.

The bullets performed admirably. My groups at 100 yards were consistently under an inch, and even at 300 yards, I was holding around 2-2.5 inches, which is excellent for my hunting rifle. There were no noticeable issues with feeding or cycling.

Ease of use was a non-issue; they loaded smoothly into my .338 Winchester Magnum. After a few adjustments to my scope, I quickly became comfortable with their trajectory and impact points. I was impressed with how quickly I found my zero.

The only minor surprise was the recoil. The 215-grain bullet, while not the heaviest for the .338, still packs a punch. It wasn’t unbearable, but noticeable compared to lighter bullets I’d used previously.

Extended Use & Reliability

After several months of using these bullets for practice and load development, they have held up exceptionally well. There were no failures to feed, no misfires, and no signs of degradation in storage. The accuracy remained consistent.

Durability has been excellent. The bullets themselves haven’t shown any signs of damage or deformation during handling or loading. My rifle’s barrel also showed no unusual wear compared to other bullet types.

Maintenance is straightforward, as with any copper-jacketed bullet. Regular cleaning of my rifle’s bore is all that’s needed. I haven’t noticed any unusual fouling or residue associated with these bullets.

Compared to previous experiences with other brands, the Sierra Bullets 338 Caliber 215 Grain SBT GameKing Rifle Bullets have exceeded my expectations in terms of accuracy and consistency. I have much more confidence with this bullet in my .338 than I did with other brands. These bullets have become my go-to hunting round.

Breaking Down the Features of Sierra Bullets 338 Caliber 215 Grain SBT GameKing Rifle Bullets

  • It has a bullet weight of 215 grain, striking a balance between velocity and energy. This is considered a lighter bullet for the .338, leading to higher velocities, flatter trajectory, and excellent expansion, making it ideal for medium to elk-sized game.
  • The Spitzer Boat Tail (SBT) design enhances aerodynamic efficiency. This translates to a flatter trajectory and reduced wind drift, crucial for long-range accuracy.
  • The sectional density is 0.269, a measure of a bullet’s penetration ability. This suggests good penetration for its weight, enhancing its ability to reach vital organs.
  • The bullet’s tip material is lead, which aids in rapid expansion upon impact. The exposed lead tip initiates a rapid expansion, maximizing energy transfer to the target.
  • The bullet’s construction includes a copper jacket and a hard core. This promotes controlled expansion and deep penetration.
