Quick Answer
Factors contributing to poor accuracy in 7mm SAUM loads include inconsistent powder charges, inappropriate bullet selection, and inadequate rifle accuracy testing.
Insufficient Rifle Accuracy Testing
To optimize 7mm SAUM loads for elk hunting, it’s essential to test the rifle’s accuracy over a reasonable distance, such as 200 to 400 yards. This helps identify any potential issues with the rifle, such as inconsistent barrel harmonics or poor scope alignment. Aim for a 1-inch or better group at 300 yards to ensure the rifle is accurate enough for hunting.
Bullet Selection and Charging
Choosing the right bullet for the 7mm SAUM is crucial. A heavier bullet with a high ballistic coefficient (BC), such as the 160-grain Berger VLD, is ideal for long-range shots. When loading, ensure the powder charge is consistent, with a deviation of no more than 1 grain between rounds. This helps maintain a stable powder burn and reduces the risk of inconsistent accuracy.
Environmental and Human Factors
Environmental conditions and human errors can significantly impact 7mm SAUM accuracy. Wind, temperature, and humidity can all affect bullet trajectory, while factors like shooter fatigue, poor shooting form, and inadequate scope adjustments can lead to inaccurate shots. To mitigate these risks, use a reliable wind gauge or ballistic calculator, practice shooting under various conditions, and ensure the scope is properly adjusted for the rifle and the shooter’s preferences.
