Hey everyone! I published the first part of an ongoing experiment which explores the relationship between the weight and volume of rifle brass. https://blog.ammolytics.com/2020-01-08/brass-sorting-part-one.html The results were pretty interesting, and I was surprised by a few of the findings. I hope that it's high quality enough to justify the time you spend reading it, and how much time it took me to create it. I'd love to hear your feedback and answer any questions!
