Effects of Case Head Thickness on Ballistics and Precision

- note: I deburred the flash hole prior to measuring case head thickness. Whatever burr or crater that exists in virgin brass needs to be removed prior to measuring. Also, my camera had some difficulty with focusing so some images may appear slightly blurry. The purpose of this video is to describe the effects of case head thickness on ballistics and precision. The findings show a linear relationship between case head thickness and velocity with thinner case heads having slower velocity relative to thicker case heads. In terms of precision, the thickness that represents the average within the range of values showed the best precision. The practical implications are discussed and include case head thickness sorting in long range shooting.
