This video compares Aguila Super Extra Standard Velocity and CCI Standard Velocity 22 LR ammunition for accuracy in a Ruger Precision Rimfire rifle. The test results indicate CCI Standard Velocity achieved a smaller average group size and mean radius, suggesting it may set a new standard for accuracy in this comparison. The instructor emphasizes proper range protocols and data analysis for ammunition evaluation.

This guide details the process for conducting an ammunition accuracy test using a Ruger 10/22, as demonstrated by Moondog. The test involves shooting three 5-shot groups for each of three different .22 LR ammunition types (Aguila Super Extra, Federal AutoMatch, CCI Mini-Mag) at 50 yards. A key technique employed is rotating the ammunition types between groups to mitigate the effects of barrel heating on accuracy, ensuring more reliable comparative data. The speaker, an experienced shooter, emphasizes structured testing to determine the most accurate ammunition for the platform.
