I explain the science and engineering of the Minie ball testing. I didn't want to give too much detail in the mail video and risk demonetization, age-restriction or worst, a strike. Youtube has told me that "children might try to duplicate our videos" even though there are real-world laws that prevent children from acquiring firearms and ammunition all ready in place. I planned to address each comment to explain some details but since there are SO many people telling us we did it wrong, calling us names and all that stuff, I decided to just address the logic we used. We didn't invent ANYTHING but used techniques all ready in place that have solved these issues.
As always, do not attempt to recreate our tests for your own safety.
