Quick Answer
A recommended twist rate for 7mm SAUM barrels is 1:8 inches. This twist rate is suitable for the 175-180 grain bullets commonly used in this caliber for elk hunting. A faster twist rate may be beneficial for longer bullets.
Choosing the Right Twist Rate for 7mm SAUM
The 7mm SAUM (Shooting Times U.S. Army Marksmanship Unit) cartridge is a versatile and powerful cartridge used for hunting large game such as elk. When selecting a twist rate for a 7mm SAUM barrel, it’s essential to consider the type of bullets you plan to use. For elk hunting, bullets weighing between 175-180 grains are popular choices.
Twist Rate Considerations for 7mm SAUM
A twist rate of 1:8 inches is a suitable choice for 7mm SAUM barrels when firing 175-180 grain bullets. This twist rate provides stability and accuracy at long ranges, making it ideal for hunting situations where shots may extend beyond 300 yards. If you plan to use longer bullets, a faster twist rate of 1:7 or 1:6 inches may be necessary to prevent bullet instability.
Barrel Length and Twist Rate Considerations
When pairing a 7mm SAUM barrel with a twist rate of 1:8 inches, a barrel length of 24-26 inches is a good starting point. This combination provides a balance between accuracy and manageability, making it suitable for hunting situations where you may need to navigate tight spaces. Keep in mind that longer barrels can provide additional accuracy, but may also increase weight and make the rifle more difficult to handle in tight situations.
