Quick Answer
Measure accuracy for handloaded .35 Whelen cartridges by firing a minimum of 5 groups at 100 yards with a consistent rifle and sighting setup, then calculate the average diameter of each group. Use a caliper or group-measuring software for precise measurements.
Setting Up for Accuracy
To accurately measure the performance of your handloaded .35 Whelen cartridges, ensure your rifle is properly sighted-in and maintained. A consistent rifle and sighting setup is crucial, as even minor variations can affect group size and consistency. For this test, use a high-quality, match-grade barrel and a reliable sighting system, such as a scoped or telescopic sight.
Group Measurement and Analysis
Fire a minimum of 5 groups at 100 yards, using the same load and ammunition in each group. This will provide a representative sample of your cartridge’s performance and help identify any potential issues with the load or rifle. Use a caliper or group-measuring software to accurately measure the diameter of each group. Record the measurements and calculate the average diameter of each group.
Interpreting Results and Adjusting Loads
Compare the average group diameters to determine the overall accuracy of your handloaded .35 Whelen cartridges. If the groups are tight and consistent, with an average diameter of 1-2 inches, your load is performing well. If the groups are larger or more inconsistent, review your load data and make adjustments as needed, such as tweaking the powder charge, bullet weight, or seating depth. Remember to test and verify any changes before firing live rounds, and always follow proper safety protocols when loading and firing ammunition.
