Quick Answer
Inconsistent accuracy in reloads can be frustrating and time-consuming to diagnose. To troubleshoot the issue, start by examining the powder charge, bullet seating depth, and bullet fit in the case. Consistency in these areas can greatly impact the accuracy of your reloads.
Analyzing Powder Charge
Consistency in powder charge is crucial for accurate reloads. A variance of 0.1 grains or less in the powder charge can significantly impact the accuracy of your rifle. To ensure consistency, use a digital powder scale and weigh the charge for each reload. Also, consider using a powder with a narrow load range, such as Hodgdon H4895, which has a recommended load range of 25.0 grains to 52.0 grains. This will help minimize the potential for errors.
Bullet Seating Depth and Fit
Proper bullet seating depth and fit are also essential for accurate reloads. A bullet that is seated too deeply or too shallowly in the case can cause inconsistent accuracy. To ensure proper seating, use a micrometer to measure the seating depth of each reload, aiming for 0.020 inches to 0.030 inches below the case head. Additionally, inspect each bullet for signs of excessive wear or damage, which can cause inconsistent accuracy.
Case Preparation and Inspection
Consistent case preparation is also critical for accurate reloads. Inspect each case for signs of excessive wear, such as excessive neck tension or case head damage. Use a case gauge to ensure each case is properly sized and seated in the chamber. Additionally, consider using cases with a uniform case head thickness to minimize the potential for inconsistent accuracy. This will help ensure that each reload is consistently accurate and reliable.
