Choosing the right ammunition for self-defense is a critical decision, demanding careful consideration of various factors. While the .308 Winchester (7.62x51mm NATO) cartridge is renowned for its power and accuracy, its suitability for home defense presents a unique set of challenges. This guide will explore the best .308 ammo options for self-defense, weighing the pros and cons to help you make an informed choice.

Always check and comply with all local, state, and federal regulations before purchasing or using any firearm or ammunition.
Why .308 for Self-Defense? A Critical Evaluation
The .308 Winchester's potent stopping power is undeniable. Its larger caliber and heavier projectiles deliver significantly more energy than common handgun cartridges. This translates to a greater potential for incapacitation of a threat. However, this power presents drawbacks in a home defense scenario:
- Overpenetration: The significant energy transfer means .308 rounds can easily penetrate walls, floors, and even neighboring structures, posing a severe risk to bystanders. This is arguably the most significant concern.
- Recoil: The substantial recoil can be challenging to manage, especially for less experienced shooters, potentially hindering follow-up shots under stress.
- Noise: The report of a .308 rifle is considerably louder than that of a handgun, potentially alerting neighbors and escalating the situation.
- Maneuverability: Rifles are generally less maneuverable in confined spaces than handguns, making them potentially less suitable for close-quarters encounters.
Ammunition Considerations for Self-Defense
Given these limitations, if you choose to use a .308 for self-defense, selecting the right ammunition becomes paramount. Here are key factors to consider:
1. Projectile Type:
- Jacketed Hollow Points (JHP): These expand upon impact, increasing stopping power while reducing overpenetration compared to full metal jacket (FMJ) rounds. This is generally the preferred choice for self-defense.
- Subsonic JHP: These rounds travel at slower speeds, reducing noise and potentially mitigating overpenetration further. However, they may sacrifice some stopping power compared to supersonic rounds.
- Avoid FMJ: Full metal jacket rounds are designed for penetration, maximizing their range and making them far less suitable for home defense due to the increased risk of overpenetration and potential harm to unintended targets.
2. Grain Weight:
Heavier projectiles (e.g., 150-168 grain) generally offer greater stopping power, but also increase recoil and overpenetration potential. Lighter projectiles (e.g., 120-140 grain) have less recoil but may offer slightly less stopping power. The optimal weight is a compromise balancing these factors, and user preference plays a role.
3. Manufacturer Reputation:
Select ammunition from reputable manufacturers known for quality control and consistent performance. Research reviews and choose brands with a proven track record.
Recommended .308 Ammunition for Self-Defense (with caveats)
While recommending specific brands is subjective and depends on individual firearm performance, look for high-quality JHP rounds from reputable manufacturers that emphasize expansion and controlled penetration. Always test your chosen ammunition in your specific firearm to ensure reliable functioning and assess its performance.
Again, we strongly emphasize that the use of a .308 rifle for self-defense should be a carefully considered choice, due to the significant risk of overpenetration. Other options, such as handguns or shotguns with appropriate ammunition, may be more suitable for home defense in many situations.
