1. Bullet Weight
Bullet weight plays a critical role in the effectiveness of .308 Winchester cartridges when used for hunting large game like brown bear. Adequate penetration is essential for reaching vital organs and ensuring a quick, humane harvest. Heavier bullets, typically 180 grains or more, retain more momentum and energy downrange, leading to greater penetration, especially through thick hide and bone. A lighter bullet, even at higher velocity, may not penetrate deeply enough for a clean kill, potentially leading to unnecessary suffering and a wounded animal escaping. This makes bullet weight a crucial consideration in cartridge selection.
Consider the difference between a 150-grain bullet and a 180-grain bullet in .308 Winchester. While the 150-grain bullet might achieve a higher initial velocity, it sheds velocity and energy more quickly over distance. Upon impact with a brown bear’s thick hide and dense muscle, the lighter bullet is more likely to deform or fragment, reducing its ability to penetrate deeply. The 180-grain bullet, with its greater mass, retains more energy and penetrates further, increasing the likelihood of reaching vital organs. The specific bullet construction also influences performance, but the overall mass remains a key factor.
Selecting the appropriate bullet weight is essential for ethical hunting and ensuring a humane kill. While other factors, such as bullet construction and shot placement, also contribute significantly, inadequate penetration due to insufficient bullet weight compromises the effectiveness of the cartridge. Hunters must carefully consider these factors and select a load suitable for the specific game being pursued. This attention to detail ensures responsible hunting practices and promotes conservation efforts.

Examples include the Barnes TSX and the Hornady GMX, which are monolithic copper bullets known for controlled expansion and deep penetration. These bullets perform well on large game, especially when bone is encountered, ensuring the bullet continues to penetrate towards vital organs.
-
Soft Point Bullets:
Traditional soft point bullets offer rapid expansion upon impact, designed for hunting thin-skinned game. However, their rapid expansion can limit penetration on larger, tougher game like brown bear. While a soft point bullet might be suitable for deer, it might not provide sufficient penetration on a brown bear, especially with a smaller caliber like .308 Winchester. Therefore, soft point bullets are generally not recommended for brown bear.
-
Full Metal Jacket Bullets:
Full metal jacket (FMJ) bullets feature a lead core completely encased in a harder metal jacket. This construction prevents expansion, resulting in deep penetration but limited energy transfer. While FMJ bullets might be adequate for target shooting or military applications, they are generally unsuitable for hunting large game due to their limited energy transfer. Their use can result in wounding without a quick, ethical kill, making them an inappropriate choice for brown bear hunting.
Choosing the correct bullet construction for .308 Winchester ammunition is essential for ethical and effective brown bear hunting.

The .308 Winchester doesn’t offer the same margin for error as larger calibers. Therefore, hunters must prioritize hitting vital organs, specifically the heart and lungs, for effective energy transfer and rapid incapacitation. A poorly placed shot, even with a well-constructed bullet, may result in wounding the bear without achieving a quick kill, leading to unnecessary suffering and a potentially dangerous situation.
Understanding brown bear anatomy is crucial for effective shot placement. Their thick hide and dense muscle mass can absorb considerable energy, further emphasizing the need for accurate shot placement. Targeting the heart-lung area provides the best chance for a quick, humane harvest. Angled shots, especially at longer ranges, present additional challenges due to bullet deflection by bone and the reduced effective diameter of the projectile. Hunters should familiarize themselves with brown bear anatomy and practice shot placement in various scenarios to increase their proficiency. A broadside shot, perpendicular to the bear’s shoulder, offers the clearest path to the vital organs, while quartering shots require careful adjustment to account for bullet trajectory and potential deflection.
Successful hunting with a .308 Winchester relies on a confluence of factors, including appropriate ammunition selection and precise shot placement.
