Introduction
Discover the Federal Power-Shok, a soft-point bullet designed for hunters who seek reliable performance at an affordable price. Introduced by Federal Premium Ammunition in the 1960s, based in Anoka, Minnesota, the Power-Shok offers classic jacketed soft-point construction suitable for a wide range of hunting applications.
Renowned for its reliable expansion and cost-effectiveness, the Power-Shok delivers effective terminal performance, making it a top choice for ethical hunters targeting medium game. Its versatile design ensures consistent results across varied hunting scenarios, from dense woods to open fields.
- Caliber Range: Available from .224 to .458 inches, supporting cartridges like .223 Remington, .243 Winchester, .270 Winchester, .308 Winchester, 30-06 Springfield, and .45-70 Government.
- Weight Options: Spans 55 to 300 grains, with popular variants like 55-grain .224, 100-grain .243, and 170-grain .308.
- Hunting Focus: Optimized for controlled expansion and penetration, ideal for medium game at short to moderate ranges.
Technical Characteristics
The Federal Power-Shok is crafted for hunters seeking dependable performance and value. Its lead-core design and proven 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.
- Soft-Point Design: Exposed lead tip ensures reliable expansion at velocities as low as 1,800 fps, achieving 1.5-2x diameter expansion.
- Flat-Base Profile: Traditional flat base enhances stability at moderate ranges and simplifies load development.
- Velocity and Range: Optimized for muzzle velocities of 2,000-3,000 fps, effective to 300+ yards with good accuracy.
- Cannelure: Includes a cannelure for secure crimping and reliable feeding in various rifles.
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 Power-Shok’s robust design excels in everyday hunts but requires careful load development.
Ballistics and Performance
With G1 BCs ranging from 0.165 to 0.439, the Power-Shok offers solid stability for moderate ranges, supported by sectional density for reliable penetration. Field tests show a 100-grain .243 Power-Shok achieving 0.8-1.5 MOA at 200 yards with ES/SD under 20 fps from a 1:10 twist barrel. The 55-grain .224 is ideal for varmints, while the 170-grain .308 excels for deer, retaining energy to 300 yards.

Comparison Bullets
The Power-Shok competes with Remington Core-Lokt (soft-point lead-core), Sierra Pro-Hunter (flat-base soft-point), and Sierra GameKing (boat-tail soft-point). Its BCs (0.165-0.439) are comparable to Core-Lokt (0.200-0.300) and Pro-Hunter (0.185-0.310) but lower than GameKing (0.323-0.517). The Power-Shok’s expansion is more controlled than Core-Lokt at high velocities (3,000 fps) but matches Pro-Hunter in penetration. Against GameKing 150gr .308, the Power-Shok 150gr .308 drops 10% more at 300 yards; versus Core-Lokt 180gr .308, it penetrates similarly with less fragmentation. Advantages: budget-friendly ($0.20-$0.40 per bullet), reliable. Drawbacks: lower BC for long-range, more drop than boat-tail designs.
| Bullet | Diameter Range (inches) | Weight Range (grains) | BC Range | Key Feature |
|---|---|---|---|---|
| Federal Power-Shok | 0.224-0.458 | 55-300 | 0.165-0.439 | Affordable soft-point |
| Remington Core-Lokt | 0.224-0.375 | 55-250 | 0.200-0.300 | Locked-core soft-point |
| Sierra Pro-Hunter | 0.224-0.458 | 55-400 | 0.185-0.310 | Flat base, soft-point |
| Sierra GameKing | 0.224-0.338 | 55-250 | 0.323-0.517 | Boat-tail soft-point |
Field reports show Power-Shok matching Core-Lokt in terminal performance but trailing GameKing by 0.3 MOA at 300 yards.

Reloading
- Load Data: Refer to Federal’s reloading manual or website for Power-Shok-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 Power-Shok’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 Power-Shok weight (e.g., 1:12 for 55gr .224, 1:10 for 100gr .243) 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 20 fps.
- Storage: Store in sealed containers to protect from moisture; suitable for all hunting applications per design.
Conclusion
Federal Power-Shok is a budget-friendly soft-point hunting bullet, offering reliable expansion and solid performance for medium game. Its affordability and versatility make it a strong choice for everyday hunters. Visit official website.
