Sierra BlitzKing Bullet: Explosive Varmint Performance

Explore the Sierra BlitzKing, a top-tier bullet for varmint hunters seeking explosive fragmentation. Engineered by Sierra Bullets, it offers precise performance from .204 to .308 calibers, ensuring powerful takedowns for small game in lead-allowed regions.

Introduction

Discover the Sierra BlitzKing, a high-performance bullet designed for varmint hunters who prioritize explosive fragmentation and rapid takedowns. Introduced by Sierra Bullets in 1999, based in Sedalia, Missouri, the BlitzKing is a lead-core bullet engineered for high-velocity applications, suitable for areas without lead restrictions.

Renowned for its explosive fragmentation and minimal pelt damage, the BlitzKing delivers devastating terminal performance, making it a top choice for ethical hunters pursuing small game and varmints. Its specialized design ensures consistent results across varied scenarios, from open fields to rocky terrain.

  • Caliber Range: Available from .204 to .308 inches, supporting cartridges like .204 Ruger, .223 Remington, .22-250 Remington, .243 Winchester, and 6.5 Creedmoor.
  • Weight Options: Spans 32 to 105 grains, with key variants like 32-grain .204, 40-grain .224, 50-grain .224, 55-grain .243, and 70-grain .243.
  • Hunting Focus: Optimized for rapid fragmentation and high shock, ideal for close-range or mid-range varmint control of small pests like prairie dogs or ground squirrels.

Technical Characteristics

The Sierra BlitzKing is crafted for hunters seeking explosive power and accuracy. Its lead-core construction and innovative features make it a standout in the field.

  • Lead-Core Hollow Point: Features a lead core with copper jacket and hollow-point design for explosive fragmentation upon impact, with low weight retention to maximize shock.
  • Polymer-Tipped Design: Features an acetyl resin polymer tip and hollow-point cavity for rapid expansion at velocities as low as 1,600 fps, achieving dramatic fragmentation for instant kills.
  • Boat-Tail Profile: Some variants include boat-tail design to increase ballistic coefficient compared to flat-base.
  • Velocity and Range: Optimized for muzzle velocities of 3,000-4,400 fps, effective to 300+ yards with good stability.
  • Reliable Feeding: Streamlined profile ensures smooth cycling in bolt-action and semi-auto 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 BlitzKing’s frangible design excels in high-speed varmint hunts but requires careful load development.

Ballistics and Performance

With G1 BCs ranging from 0.145 to 0.270, the BlitzKing provides solid mid-range stability and wind resistance, bolstered by moderate sectional density for explosive effects. Field tests show a 55-grain .224 BlitzKing achieving 0.5-0.9 MOA at 200 yards with ES/SD under 15 fps from a 1:10 twist barrel. The 32-grain .204 is ideal for prairie dogs, while the 70-grain .243 excels for larger varmints like foxes, maintaining energy to 300 yards.

Comparison Bullets

The BlitzKing competes with Hornady V-Max (polymer-tipped) and Nosler Varmageddon (tipped varmint). Its BCs (0.145-0.270) are comparable to V-Max (0.150-0.275) and Varmageddon (0.140-0.265), offering similar mid-range performance. The BlitzKing’s fragmentation matches V-Max at high velocities (3,000 fps) but achieves 5% more explosive effect than Varmageddon. Against V-Max 50gr .224, the BlitzKing 50gr .224 drops 5% less at 200 yards; versus Varmageddon 55gr .224, it fragments 10% more consistently. Advantages: explosive power, cost-effective ($0.30-$0.50 per bullet). Drawbacks: lower BC for longer ranges, contains lead.

Field reports show BlitzKing matching V-Max in fragmentation consistency but outperforming Varmageddon in explosive effect at 200 yards.

Applications and Practical Aspects

Ideal for hunting:

  • 32-39gr .204 for prairie dogs and small varmints;
  • 40-55gr .224 for ground squirrels or coyotes;
  • 55-70gr .243 for foxes or larger varmints;
  • 105gr .264 for mid-range small game.

Delivers 0.5-0.9 MOA in tuned rifles, ideal for ethical kills.

Reloading

  • Load Data: Refer to Sierra’s reloading manual or website for BlitzKing-specific data, as the lead-core design generates standard pressures similar to other varmint bullets.
  • Starting Charges: Begin 5-10% below maximum loads for comparable varmint 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 BlitzKing’s hollow point is sensitive to inconsistencies.
  • Crimp Application: Apply a light to medium crimp for secure bullet retention, particularly in semi-auto or high-recoil rifles, ensuring reliable feeding.
  • Barrel Twist Compatibility: Match barrel twist rate to BlitzKing weight (e.g., 1:12 for 40gr .224, 1:10 for 55gr .224) for proper stabilization and optimal accuracy.
  • Velocity Check: Chronograph to confirm velocities above 1,600-3,000 fps for reliable fragmentation, targeting extreme spreads under 15 fps.
  • Storage: Store in sealed containers to protect from moisture; suitable for all varmint applications per design.

Conclusion

Sierra BlitzKing is a premier varmint bullet, combining moderate ballistic coefficients with explosive fragmentation and accuracy. Despite containing lead, its performance makes it ideal for hunters targeting small pests in unrestricted areas. Visit official website.
