Always consult the manufacturer's data for precise specifications for any specific lot of ammunition.
Performance Characteristics of 30-06 M2 Ball
The 30-06 M2 Ball cartridge's performance characteristics have contributed to its enduring legacy. Its combination of velocity and bullet weight delivers significant stopping power at medium to long ranges.
- Effective Range: While the maximum range is considerable, the effective range for accurate, consistent hits on a human-sized target is typically considered to be around 800 yards (730 meters) depending on shooter skill and environmental factors. Beyond this distance, factors like bullet drop and wind drift significantly impact accuracy.
- Ballistics: The 30-06 M2 Ball's trajectory is relatively flat for its power level. However, accurate shooting at longer ranges requires careful consideration of bullet drop compensation.
- Penetration: The full metal jacket bullet provides good penetration, making it effective against both soft and hard targets.
