The .308 Winchester cartridge, a stalwart in the world of hunting and long-range shooting, offers a wide variety of bullet weights. While lighter bullets excel in flatter trajectories and higher velocities, heavier options like the 220 grain 308 bullets provide distinct advantages, particularly for hunters seeking maximum knockdown power and long-range precision. This article delves deep into the characteristics, applications, and performance of these heavyweight projectiles.
Understanding the Advantages of 220 Grain 308 Bullets
The primary benefit of a 220-grain bullet in a .308 Winchester is its increased sectional density. Sectional density (SD) is a crucial ballistic coefficient factor representing a bullet's ability to overcome wind resistance. A higher SD means less wind drift and better accuracy at longer ranges. This is especially important when hunting large game animals at extended distances where wind can significantly affect shot placement.
- Greater Momentum: Heavier bullets carry more momentum, meaning they retain more energy upon impact, leading to superior penetration and knockdown power. This is critical for ethical hunting, ensuring a clean kill with minimal suffering for the animal.
- Reduced Recoil: While seemingly counterintuitive, heavier bullets can sometimes lead to slightly less felt recoil due to their lower velocity. This allows for faster follow-up shots and improved accuracy for less experienced shooters.
- Superior Performance on Large Game: The increased energy and penetration of 220-grain bullets make them ideal for taking down larger game animals such as elk, deer, and even some species of bear. Their ability to penetrate thick hides and bone is significantly greater than lighter bullets.
Ballistic Coefficient and Trajectory
The higher sectional density directly impacts the ballistic coefficient (BC) of the bullet. A higher BC means less energy loss due to air resistance, resulting in a flatter trajectory. This flatter trajectory makes it easier to compensate for distance and wind, crucial factors in long-range shooting. While not as flat-shooting as lighter bullets at shorter ranges, the 220 grain bullet excels in maintaining energy and accuracy at longer distances.
Bullet Construction and Types
220-grain .308 bullets are available in various constructions, each tailored for specific purposes.
- Full Metal Jacket (FMJ): These are designed primarily for target practice and are not suitable for hunting due to their limited expansion capabilities.
- Soft Point (SP): Soft points offer good expansion and penetration, making them a versatile choice for hunting various game animals.
- Boat Tail: The boat tail design improves the bullet's ballistic coefficient, leading to better accuracy and less wind drift. This is especially beneficial at longer ranges.
- Controlled Expansion: These bullets are designed to expand reliably, while maintaining sufficient penetration to reach vital organs, ensuring a clean kill. This feature balances penetration and expansion.
Table 1: Comparison of Bullet Types
| Bullet Type | Expansion | Penetration | Application |
|---|---|---|---|
| Full Metal Jacket | Minimal | High | Target Practice |
| Soft Point | Moderate to High | Moderate | Hunting |
| Controlled Expansion | Controlled | High | Hunting (Large Game) |
| Boat Tail | Varies | Varies | Improves Accuracy |
Applications of 220 Grain 308 Bullets
The 220-grain .308 bullet shines in specific applications:
- Long-Range Hunting: Their superior ballistic coefficient and energy retention make them a preferred choice for hunters who engage targets at longer ranges.
- Large Game Hunting: The increased penetration and knockdown power are crucial when hunting elk, deer, and other large game animals. Ethical hunters appreciate the increased chances of a clean kill.
- Controlled Fire situations: Their greater stopping power is valued in situations that demand absolute stopping power.
Case Study: Elk Hunting with 220 Grain Bullets
A hunter using a .308 Winchester with 220-grain controlled expansion bullets successfully harvested a mature bull elk at 300 yards. The bullet's superior penetration and expansion ensured a clean kill, minimizing suffering for the animal. This exemplifies the effectiveness of these bullets in demanding hunting scenarios.

Choosing the Right 220 Grain 308 Bullet
Selecting the proper 220-grain .308 bullet depends on the intended application. Consider the following factors:
- Bullet Construction: Choose a bullet type (SP, Controlled Expansion, etc.) appropriate for the game you intend to hunt.
- Ballistic Coefficient: A higher BC will translate into better accuracy and less wind drift at longer ranges.
- Manufacturer Reputation: Select bullets from reputable manufacturers with a proven track record of quality and consistency.
Conclusion:
220-grain .308 bullets offer a compelling combination of accuracy, penetration, and knockdown power, making them an excellent choice for specific hunting and long-range shooting scenarios. Understanding their advantages and limitations allows you to choose the correct ammunition for your specific needs, ensuring ethical hunting practices and reliable performance. Remember always to practice safe firearm handling and follow all relevant hunting regulations.
