- Weight Options: Spans 64 to 180 grains, with key variants like 64-grain .224, 130-grain 6.5mm, and 180-grain .308.
- Hunting Focus: Optimized for accurate placement and controlled expansion, ideal for medium game at mid to long ranges.
Technical Characteristics
The Sierra Tipped GameKing is crafted for hunters seeking unmatched accuracy and reliability. Its lead-core construction and innovative features make it a standout in the field.
- Lead Core with Copper Jacket: Features a lead core encased in a copper jacket for high weight retention and controlled expansion, preventing excessive fragmentation.
- Polymer-Tipped Design: Includes a green polymer tip and hollow-point cavity for rapid expansion at velocities as low as 1,800 fps, achieving 1.5-2x diameter expansion.
- Boat-Tail Profile: Streamlined boat-tail design enhances ballistic efficiency and reduces drag for flat trajectories.
- Velocity and Range: Optimized for muzzle velocities of 2,000-3,500 fps, effective to 500+ yards with excellent stability.
- Optimal Jacket Thickness: Tuned jacket wall controls expansion and retains weight, suitable for medium game.
Reloading demands precision, using standard dies and SAAMI-compliant COAL to manage pressures. Maintain case neck tension (0.002-0.004″) for optimal accuracy, as the Tipped GameKing’s design excels in varied hunts but requires careful load development.
Ballistics and Performance
With G1 BCs ranging from 0.323 to 0.535, the Tipped GameKing provides superior long-range stability and wind resistance, bolstered by high sectional density for reliable penetration. Field tests show a 130-grain 6.5mm Tipped GameKing achieving 0.5-0.8 MOA at 300 yards with ES/SD under 15 fps from a 1:8 twist barrel. The 64-grain .224 is ideal for varmints and small game, while the 180-grain .308 excels for medium game like deer or elk, maintaining energy to 400 yards.

Groups of 0.5-0.8 MOA achievable; excels to 500 yards with proper shot placement.
Comparison Bullets
The Tipped GameKing competes with Hornady SST (polymer-tipped lead-core) and Nosler Ballistic Tip (polymer-tipped lead-core). Its BCs (0.323-0.535) are comparable to SST (0.300-0.530) and Ballistic Tip (0.310-0.531), offering similar long-range performance. The Tipped GameKing’s expansion is 5-10% more controlled than Ballistic Tip at high velocities (3,000 fps), but matches SST in penetration. Against SST 140gr .270, the Tipped GameKing 140gr .270 drops 5% less at 400 yards; versus Ballistic Tip 150gr .308, it penetrates 5% deeper with less fragmentation. Advantages: superior accuracy, high BC. Drawbacks: less violent expansion than Ballistic Tip, slightly higher cost ($0.35-$0.60 per bullet).
| Bullet | Diameter Range (inches) | Weight Range (grains) | BC Range | Key Feature |
|---|---|---|---|---|
| Sierra Tipped GameKing | 0.224-0.308 | 64-180 | 0.323-0.535 | Polymer tip, boat-tail lead-core |
| Hornady SST | 0.224-0.338 | 55-180 | 0.300-0.530 | Polymer tip, interlock ring |
| Nosler Ballistic Tip | 0.224-0.338 | 55-180 | 0.310-0.531 | Polymer tip, boat-tail |
Field reports show Tipped GameKing leading SST by 0.2 MOA at 400 yards and outperforming Ballistic Tip in penetration consistency.

Delivers 0.5-0.8 MOA in tuned rifles, ideal for ethical kills.
Reloading
- Load Data: Refer to Sierra’s reloading manual or website for Tipped GameKing-specific data, as the lead-core design generates standard pressures similar to other jacketed bullets.
- Starting Charges: Begin at recommended loads for comparable lead bullets to avoid over-pressure; increase gradually while checking for pressure signs.
- Seating Consistency: Ensure precise seating depths (0.010-0.050″ off lands) to maximize accuracy, as the Tipped GameKing’s profile is sensitive to inconsistencies.
- Crimp Application: Apply a light to medium crimp on the cannelure for secure bullet retention, particularly in semi-auto or high-recoil rifles, ensuring reliable feeding.
- Barrel Twist Compatibility: Match barrel twist rate to Tipped GameKing weight (e.g., 1:9 for 64gr .224, 1:8 for 130gr 6.5mm) for proper stabilization and optimal accuracy.
- Velocity Check: Chronograph to confirm velocities above 1,800-2,000 fps for reliable expansion, targeting extreme spreads under 15 fps.
- Storage: Store in sealed containers to protect from moisture; suitable for all hunting applications per design.
Conclusion
Sierra Tipped GameKing is a premier hunting bullet, combining high ballistic coefficients with match-grade accuracy and controlled expansion. Its precision and reliability make it ideal for hunters targeting medium game at extended ranges. Visit official website.
