The exit wound from a standard .30-06 rifle round depends on several factors, including bullet type, velocity, range, and what the bullet strikes (e.g., tissue, bone). Generally, a .30-06 round, commonly used for hunting, produces significant tissue damage due to its high velocity (around 2,700–3,000 fps) and energy (approximately 2,800–3,000 ft-lbs at the muzzle).
For soft tissue (e.g., hunting game like deer), a typical exit wound from a standard 150–180 grain soft-point or ballistic-tip bullet might be:
- **Size**: 1–3 inches in diameter, often larger than the entry wound due to bullet expansion and cavitation.
- **Appearance**: Irregular, ragged edges with significant tissue disruption. The wound may appear "blown out" due to the temporary wound cavity caused by the bullet’s energy transfer.
- **Factors affecting size**:
- **Bullet type**: Expanding bullets (e.g., soft-point, hollow-point) create larger exit wounds than non-expanding (e.g., FMJ) rounds.
- **Range**: Closer shots retain more energy, causing larger wounds.
- **Tissue/bone interaction**: Hitting bone can fragment the bullet or cause it to tumble, increasing wound size.
For example, on a deer, a .30-06 soft-point bullet at 100 yards often leaves a 2–3-inch exit wound if it passes through soft tissue. If it hits bone, the wound could be larger and more irregular.
